I have been going here since I was very young (about 20 years) and my parents have been going here for even longer! I no longer live in the state but will schedule appointments when I visit (that’s how much I trust them).They are incredibly thorough and professional. They’ve taken care of every problem we have ever had with integrity. They are always very thoughtful and do an amazing job! Thank you to Dr. Erwin and amazing staff!

I was in so much pain I had new insurance that I had gotten just before covid and I hadnt used it yet so I didnt know if I was covered I must have called half a dozen. Dentist that morning and no one returned my call except doctor Iwins office they work so hard to try to find out if I was covered in to get me in. Unfortunately I never got a chance to see dr Irwin by the time my husband came home from work he took me to emergency it turns out I have a massive sinus infection they gave me Phantom toothache. all the dentist I called that morning no one returned my call except dr. Irwins office and they worked all day to try to get a hold of my insurance which apparently was down for updating it took several hours by the time they got a hold of my insurance though I was at hospital. But they kept going and they found out if I was covered I was so impressed with all the work they put in on my behalf not knowing if I was even going to be a patient I want to thank everyone at dr. Irwins office for being the only ones there for me that morning and the only ones who tryed to help me I plan to see dr. Irwin for all my future Dental needs as soon as I get over this nasty sinus infection I want to say thank you so much to all the staff at dr. Irwins office and hope to see you all soon thank you. Dr. Irwin you have a great staff.

I have been going to Irwin Dentistry since I was a little girl! They have always taken care of me and are the most caring people. My family and extended family also have been coming here for years and years. Everything is clean, modern and organized! Cant refer them enough!

Ive been coming here for almost 15 years. The staff always greets you and makes you feel welcome. For my appointments, I am always seated within 5 minutes of arrival. They always do their best to make you feel comfortable while getting work done. They have tv to watch, glasses to block out the light, and even offer headphones now. Dr. Irwin always stops by to say hello and ask about my family and I, even though I know he has plenty of work to get done. All around this place is great.

I was referred to Dr Irwin by my husband’s family who has been coming for years. I’d had a bad experience at another and everyone there instantly made me feel comfortable. They are honest, I didn’t feel as though they were trying to sell me unnecessary work. Dr Irwin is awesome and the whole staff is so nice, taking the time to make you feel important, it’s very much a family vibe. I live 35 mins away but drive the extra distance to come to this office because I feel so well taken care of. Highly recommend!!

We have been going to Dr Irwin for 20 years because of his professionalism and his outstanding staff. From Cindy in the front office to the dental assistants/ staff each are friendly and professional. They treat you like family. We drive from a Placentia and even though family members no longer work or attend school near Whittier...we make the trip because we are extremely happy with Dr. Irwin and his team.

I have been going to Dr Irwin for 16 years. From the moment I walk in to their friendly greeting, I feel welcome. The cleanings are painless and great. And the doctor and assistant are more like friends. I trust them 100% with my teeth!!

Dr. Irwin is the best dentist I have even been too. I grew up going to him and now I bring my kids to him. The staff is friendly and sweet.

I have been going to Irwin dentistry for many years. I recommend them very highly because of the work quality and staff professionalism They truly have the best staff of any business I deal with. I have had excellent results with all my dental work and have had Dr.Irwin fix a lot of bad work done by prior Dentists. On a scale of 1-10 they are definetly a 10. The only Dentist in my life that i dont dread going to.

Been coming here for years. Everyone here is always professional and so friendly. Great place!

Excellent and friendly staff. Ive needed more frequent cleanings and treatment than usual due to my particular issues, and so I have seen the hygienists on shorter intervals than might be typical. They have been top notch and have really helped keep more serious problems in check.

OUTSTANDING OFFICE--I can smile again when i think about having cleanings or dental work. The staff and Dr. Irwin are incredible. They make you feel so welcomed and special. I really appreciate their kindness.

After years the wrong dentist we I was lucky to have Irwin dentistry. They are always friendly and kind and keep my teeth healthy. I recommend them highly.

I have been a dental patient of this office for about 30 years and I havent ever considered going anywhere else. Even when I lived in a different part of the state for 5 years I made sure to schedule my appointments around my visits to So Cal. I have highly recommended them to my friends and colleagues!

Great service all around! Theyre always very welcoming and efficient with their work! I would definitely recommend them!

Its a good place I love it

Dr. Irwin and his staff is always very friendly, and always provides great service. Thank you guys!
