Excellent staff - everyone I interacted with was friendly, knowledgeable, and professional. I was highly anxious as I often am when going to the dentist, and they were all very comforting and accommodating. I had a fabulous dentist in Denver for many years and was extra nervous switching to someone new. Dr. Ribbens is wonderful, and he took the time to explain everything to me and made sure I was comfortable throughout the visit. This is a gem of a dental office and Im happy to have found them. Highly recommend!

My experience here was okay.My initial consult: Since I hadnt been to the dentist regularly prior to this visit, I had several things that needed addressed, which included a deep cleaning, fillings that needed to get replaced, and adding bonding to my front teeth from an accident when I was younger. There wasnt anything necessarily wrong with their approach, but it was aggressive and part of me questions if they wanted to make a few extra bucks.Heres why:Lets start with the positive: My deep cleanings with Dallas were great. She made me feel very comfortable and did a wonderful job.Fillings that required crowns: Dr. Ribbens told me 2 of my fillings required crowns. Fortunately, my father is a retired endodontist (root canals) and took a look at my X-rays. While the fillings are wide and theres a crack between the teeth that need crowns, my margins were still in tact and the crack was superficial. My dad didnt think I needed crowns and I went back for a 2nd appointment to address my concerns. Dr. Ribbens told me he could do the fillings but he didnt recommend it and would be very nervous while doing them. Who wants a dentist to be nervous while working in their mouth?! Obviously I trust my fathers opinion far more than here, so I canceled my appointments and got a 2nd opinion at a practice in Longmont. The dentist in Longmont did an extremely thorough consult (more thorough than here) and told me I only need fillings. If the crack appears larger once he takes out the existing filling, then maybe wed need crowns but since the teeth arent hurting, he feels confident that they just needed new fillings.Gum analysis: Dr. Ribbens told me I had 4-6 inch pockets in some areas of my gums. I needed a deep cleaning, which I completely agree with. The dentist in Longmont told me that my gums look great and the only concern is in one place thats a 4 inch pocket. Its entirely possible the deep cleanings resolved this, but from almost half of my mouth to go from a 4-6 inch pockets to very healthy gums is questionable.Front teeth that need bonding: They tried to upsell me on veneers. Yes, maybe ideal, but given my bonding has worked just fine for 30+ years, thats what I want. Dr. Ribbens told me hed have to remove all the existing bonding and replace it with new bonding. The dentist in Longmont told me only the bottom of my teeth needed to be repaired where its chipped. The rest didnt need to be touched since its holding up nicely. Thats how all other dentists have handled my bonding in the past and I fully agree with this approach.Yes, Im lucky because my father was an endodontist and was able to look at my images and point me in another direction to save my natural teeth. This place has really great reviews, which is why I initially went there, but I had a weird gut feeling at my first appointment.My point in all of this -- if it doesnt feel right, get a 2nd opinion. I genuinely believe they are trying to do whats best for their patients, but their approach may be more aggressive than others and I question if they are trying to make a few extra bucks in between.

Overall a MUCH better experience than all my past dentists at Comfort Dental. The front desk is so friendly, the dentist (Dr Ribbens) is very patient, and the dental assistant made sure to explain everything thoroughly to me and answered all my questions! They were fixing some cavities that Comfort Dental did poorly and I couldn’t be happier with how they turned out. They let me watch Netflix during my cavities and had a massage chair as well. As uncomfortable as the dentist is, they made sure it was the most comfortable dental experience I could have. 10/10 would recommend!

Great team! I always receive the treatment needed and feel very comfortable in the office!

Dr. Nick and team are amazing. I felt so relaxed the entire time. It had been a couple years since my last cleaning and thought I might be given a hard time for that, instead I got the most laid back dental experience Ive ever had. Im also very happy with the work. It was just a cleaning and check up but the x-rays were comfortable and the cleaning didnt hurt at all. I highly recommend this establishment. If youre looking for a good dentist, do yourself a favor and check this place out.

Ive been a patient of Dr Sigman for many years ... following him to Performance Dental when he opened his own practice. He is competent, professional and personable. All of the staff are very friendly and competent too. The facility is clean, modern and easily accessible .... who could ask for anything more? I truly look forward to going to the dentist now.

Good Morning!! I just wanted to let you all know what a GREAT experience I had with this office yesterday with my fillings. The last time I had a filling it was a brutal experience - lots of pain and pressure during the procedure and swelling, bruising, and pain the next day and this was the reason I was very anxious and apprehensive about getting two fillings done yesterday. There was none of this when I came in to Performance Dental yesterday. Even the numbing shots were pain free. Dr. Stegman and the entire staff were beyond gentle. The numbness wore off in just a couple of hours after the procedure and there was absolutely no pain, bruising or swelling then or today. Thank you all so much for changing my mind about dental procedures in your office. Dental appointments are still not on my top 10 list of fun things to do, but are certainly no longer on my top 10 of horrible experiences!! Thanks again for the great experience!!!

Very knowledgeable dentists and technicians, super nice front office staff, the dental seats even have light massagers so youre comfortable during procedures. I was afraid of having a bad insurance experience and they said they would go out of their way to submit a pre-authorization form with my insurance to get an accurate estimate.

Recently I had a teeth cleaning here and it was excellent. The hygienist (Dallas) was very thorough and gentle and I appreciated the doctors cool and professional manner. The office is small and clean and easy to access. Overall I give them 5 stars!

Unfortunately can not recommend. My experience here involved hundreds of dollars in unexplained fees, a crown that fell out after only days, a resistance to renegotiate fair treatment, and a refusal to correct and complete the work. So disappointing. I wanted to like this place, but now I regret trusting them.

Love this place. Modern, new technology and environment with completely skilled and friendly staff. There is nothing more comforting than a dentist and hygienist who really work together. Everything got done so fast, and this was by far the least painful crown work EVER. Definitely recommend.

I recently had a cleaning done here with Dr. Sigman and his hygienist, Dallas. I was pretty nervous, because I had not been in to see the dentist in over three years! They were both extremely nice and didn’t make me feel guilty for not keeping up with my oral health the way I should. Dallas was very gentle during my cleaning and frequently checked in with me to make sure I was doing okay. She even followed up with me the next day to see how everything was feeling! I am so thankful to have found them and highly recommend this office.

I honestly had been looking for a while for a dental practice whose doctor and office staff would make one feel welcome and who would honestly care about you as a patient and a human being and not a source of income when I stumbled upon Performance Dental Center. Dr. Sigman and his office staff have provided that environment for me. I have found a dentist that is caring and knowledgeable. From cleaning, to cavities, and crowns his service has surpassed my expectations. Gone are those usual feeling of uneasiness and nervousness that one may regularly experience before visiting a dentist. In addition to his exceptional service as a dentist, I love his caring and welcoming staff and the great music selection they have as one is being treated.

I have been seeing Dr.Sigman for years. I appreciate his honesty and hard work. The staff at Performance Dental is very friendly. I enjoy being greeted by name when I walk up stairs. Its easy to schedule appointments even if they are last minute or emergency. Their office is comfortable and clean. Thank you for all that you do!

The nicest dental office I’ve been to. The staff is friendly and professional, facility is clean and up to date. They even have massaging dental chairs! I will definitely be going back for my next cleaning.

I couldn’t recommend Dr. Sigmund and his team more!! I chipped a veneer recently and found out I also needed a root canal and they were SO helpful in working with me to get everything fixed in a incredibly timely matter. I re-did my front four veneers with Dr. Sigmund and they look better than I could have ever imagined. They go above and beyond with their patients. I HIGHLY recommend them for any dental work and wouldn’t go anywhere else!

Nick was very friendly and explained everything well. The teeth cleaning wasnt painful like it is at most dentists I have gone too. Also, I was made a mouth guard and wasnt gagging while getting my mold made like I did at my other dentist. Easily the best dentist Ive gone to. Highly recommended. The dental assistant was also a sweetheart.

The staff is awesome! They are super friendly and quick to answer questions. Dr. Sigman is great. He was very kind and made sure that I was totally comfortable the entire time. I have never had a positive experience at the dentist until now!

They have beer in the lobby – what more could you want? But really, I was very impressed with my first visit to this dental office and look forward to being a longtime patient. The hygienist and dentist (Dallas & Dr. Sigman) were very friendly, down-to-earth, and made an experience that people usually dread enjoyable.

Dr. Sigman is awesome! He is super nice, thorough, and an interesting fellow. The staff is friendly, the facilities are clean and they play classic rock. What more could you ask for? A massaging chair? Oh wait... they have that.

We selected this dentist because it is close to our house and accepts our insurance. The scheduling and paperwork were pretty painless and everyone is cheerful and professional. This is the first time Ive had my teeth cleaned personally by the dentist since I was a kid. I was really impressed by the amount of time the dentist spent with me, how amazing my cleaning was (no offense hygienists out there, it was just next level to what Im used to) and the fact that there werent any aggressive upsells on random products.

I had the best experience Ive ever had at a Dentist. The staff was professional, made me feel comfortable, and gave clear explanations. The shoulder/back massaging dentist chair made the experience that much better!

Great dental office! Dr Nick explains everything in simple terms, doesnt push additional services as some corporate offices do. Very nice modern office, and staff is veryhelpful. Highly recommend!

I couldn’t be happier with my experience at Performance Dental. Dr. Sigman and his staff are friendly and professional. My teeth cleaning sessions have been quick and painless while the couple fillings I’ve had were very well done. I recommend Performance Dental to all my friends in the Boulder area.

Super nice experience everyone was very friendly. Nice paced service, didnt feel rushed or stressed, but was done sooner than I expected. Very comfortable! Also very reasonable out of pocket cost. Looking forward to going back.

These guys amaze me.Theyve gone above and beyond for me every time Ive needed them.As a person who doesnt do ANY white-coat situation well, i am calm and comfortable in Dr. Sigmans office.Though i hope to not see them again for quite a while, Ive appreciated my time there.

They were able to get me in very quickly. Staff was incredibly down to earth and helpful. They were even able to find insurance I wasnt aware that I had. If you want the pros, here they are.

One of the nicest dental offices I have had the pleasure of visiting. Very relaxing environment and the staff is wonderful. Nicholas is extremely professional, down to earth, and does great work. I would highly recommend Performance Dental Center to anyone I know in the Boulder or Longmont area.

Really friendly team from the front desk to the owner but also very professional and clearly very talented. I’ve had many dentists over my life time and I’d recommend Performance Dental above them all.

Ive been going to Dr. Sigman at Performance Dental for over a year now and been very happy! He and his staff are very thorough, gentle, and personable. Really solid and would definitely recommend!

These guys answered all my questions and made me feel comfortable and taken care of. Im so happy I found this place! I wont be going anywhere else.

The friendliest office I’ve ever been to. Very helpful and informative, highly recommend for anyone looking for a dentist. Nick and Denise are lovely.

Office staff was amazing! Dallas was very friendly and professional, and Dr. Sigman was great. He did an amazing job at my fillings. I highly recommend Performance Dental Center.

I have very happy with Dr Sigman and his staff! He is very gentle and caring, explains every detail of the work being done and makes sure you are ok and in no pain.The facilities are the best I have ever seen at a dentist office! And the technology is the latest greatest. The dental chair even gives you a soft gentle massage.The staff is very helpful and friendly, making you feel very welcome.Highly recommended!

Made going to the dentist fun and relaxing. Such amazing service and the cleaning felt less invasive and my teeth feel sparkly and so clean! Ive already referred them to my friends! ⭐️⭐️⭐️⭐️⭐️😁

Excellent experience for a dentist office! Great communication, customer service and made me feel important. Highly recommend!

Such a great experience! This is coming from someone that had dentist-phobia. All of my questions were answered and I things were explained to me beforehand, so I was comfortable.

Performance Dental is the best! Dr. Sigman is meticulous, informative, conscientious, and genuinely helpful. I had two appointments recently because the cleaning and x-rays turned up a couple cavities. I was happy with Dr. Sigmans work on both occasions and especially enjoyed his sweet, funny dental assistant. The office space is modern, minimalist and elegant (love the artwork!), they provide plush blankets for people like me who are always chilly, and the chairs gently massage your back while the dentist works. Who knew going to the dentist could be a relaxing experience?! Performance Dental provides a five-star experience in every sense of the word.

I LOVE this place. Not only is the staff knowledgeable and friendly their practice is imaculate. There is a wonderful view of the mountains and their chairs massage you as they work. They managed to do my root canal with almost no pain and gave me the option to watch Netflix as they did it. I highly recommend them.

Performance Dental is my new favorite area dentist. Kind, communicative, and prompt service. I have switched to Perfomance for all future dental work. Highly recommended.

Full disclosure, unlike most people, I love going to the dentist. Nevertheless, Dr. Sigman and his staff gave me the best experience Ive had in a long time. By the time I left I knew all their names, including his dog Slash, and I cant even remember my coworkers names. I actually have a bit of a fear of dogs, but Slash, who was visiting for the day was the sweetest and I felt comfortable getting on all fours to play with him.They actually had good conversation, and have mastered the art of dental conversation so that the patient can actually respond. They take the time to explain everything thoroughly, the doctor even indulged my curiosity about cranial nerves.More importantly, he treats you like family, and has a strong philosophy of not treating more than he can handle or that is unnecessary, unlike some more unscrupulous dentists out there.In short, I cant recommend Dr. Sigman highly enough.

They got my daughter in on short notice and took great care of her! It is very much appreciated!!! Thank you!!!

My first experience at Performance Dental Center has been the best dental experience I have had thus far. Nothing that Dr. Sigman or his hygienist did during my exam hurt or felt uncomfortable. Everyone was friendly and welcoming. Dr. Sigman takes the time to review and explain x-rays and he is able to explain dental conditions in a way that is easy to understand, while providing realistic outcomes and solutions for said conditions. The office itself is beautiful and it also has massage chairs! Best experience at the dentist, by far!!

Great dentist - highly recommend! Friendly, informative and painless cleaning experience.

Ive worked for a number of different dentists and its fairly easy for me to spot out the good ones. My first visit I was extremely satisfied and excited to see where Dr. Sigman and Denise would take this practice, but after returning I was disappointed by the new hygienist they hired. She is unprofessional, pushy, and Ive never had my gums hurt after a hygiene cleaning before, but she ripped mine apart. All the while loudly speaking about herself the entire appointment and explaining to me that she had only 6 years experience and lecturing me far more than was necessary. The several people I suggested to go to Dr. Sigman admitted to me that they wont be returning because of their experience with her and unfortunately either will I. This is sad because there was a lot of potential with this practice. I hate to leave a poor review because the doctor and Denise are amazing, but the word needs to get out there that his hygienist, even though she was his friend in dental school, is hurting his business and changed the environment there completely.

Dr. Sigman and his staff were incredibly accommodating, friendly, and professional. They contacted me within an hour of my inquiry, made a same day appointment for me, and stayed late to give me a crown before I left town for 10 day vacation so I would be comfortable while out of town. As a first time patient, they went above and beyond to make sure I was taken care of and relaxed throughout the visit. I typically experience a great deal of apprehension and avoid the dentist, but after this appointment where I was given my first crown, I will return to Dr. Sigman regularly. Thank you, Dr. Sigman and staff, for your exceptional care!

I have been bouncing around for the last few years and during that time I have been to many different dentists. I can say confidently that Dr. Sigman and his team are by far the best dental office I have ever been to!I was having extreme gum pain, without even being a patient Dr. Sigmans office got me in the following day. I ended up having an infection which needed a root canal. After that first appointment I knew I was going to be a regular patient of his.They are always accommodating with scheduling, have the latest and greatest in tools and being able to watch Netflix while they are working away in my mouth helps as well!

Im very happy with the folks at Performance Dental, great service in a pleasant atmosphere.

Always super comfortable, easy, convenient. Highly recommend!

Excellent care. Fast and thorough service.

A wonderful experience!! Very knowledgeable and caring staff!!

The PDC is a dentist office that isnt cold, stale, and scary - this coming from someone who hates dentists and has spent way too much time in them. Dr. Sigman is really nice and fun. He talks to you like a human, so you understand everything thats going on. Hell give you his honest opinion and doesnt try to upsell you unnecessary services. One of the best parts of his office: watching Netflix while sitting in a MASSAGE chair! It was a nice surprise (and distraction!) to be able to watch a show while he was working on my teeth. Id definitely recommend going to Performance Dental if you want a great dental experience - three words I never thought Id say together.

Awesome dental office and staff!!

Fast and thorough.

Performance Dental is wonderful!

Professional and friendly.
