I can’t say enough about this practice! They are wonderful from the physicians down to the staff. Dr Shawn and Dr Katherine are extremely knowledgeable in their field of expertise. As someone who has worked in the healthcare industry for the past 22 years one of the ways these two stand out the most to me is their dedication to continued learning. They are always up on the latest and greatest techniques and services and available to offer these to their patients. You simply can’t go wrong giving Optimal Self MD a visit!

Knowledgeable care given in a compassionate, understandable manner. Dr. K takes the time to listen to you and discover the root of your issue. She explains tests results in a way that makes sense. During a time when health care has received the personal aspect of care, Dr K and her caring staff far exceeded my expectations . Her delightful staff provided excellent and gentle care .

Dr. Katherine Birchenough (and the entire staff) are warm and welcoming. Dr. Katherine took ample time to listen to my concerns and collaborate on my options. We spent several months testing and exploring options to heal my body and optimize my health. I feel it has been a great learning experience and I am better equipped to continue my journey of healing and health. I’m glad that I saw her and I would recommend her services to others.

Dr. Katherine is wonderful! From the moment you enter the practice Ashlee makes you feel welcome. This continues as you meet Dr.Katherine and her amazing team. She takes time to listen to you, helps you establish realistic goals for your health, and actually gets you there! She has helped get me off multiple medications and sleeping well for first time in my life! I would HIGHLY recommend this practice to anyone!

I had been struggling with GI issues and severe stomach pain for months, had paid thousands to specialists, none of whom were able to effectively treat my pain. Dr Katherine and her awesome staff took a holistic approach to my healing. Along with identifying a number of issues the other doctors missed in their hyper-focused areas of practice (food allergies, genetic predispositions, nutrient deficiencies and more), she provided actionable lifestyle guidance, medication, and support. The holistic approach has drastically improved my quality of life!

Fantastic practice offering functional medicine perspective and aesthetic plastic surgery options. I enjoy seeing the Staff and appreciate the functional medicine birds eye view regarding my healthcare. Very high marks from me!

When I first came to see Dr. Katherine I was at my lowest point. She has been super fantastic...!!! I now feel the best I’ve ever felt. Her staff is the most polite and kindhearted people ever...!!! What at GREAT experience I’ve had there. I can’t recommend her enough.

Great group, always concern how Im doing. Always remembers my likes/dislikes, treats me like family.

Staff always has a warm greeting when you enter. Everyone is very accommodating and the costumer service is excellent. Eliza does beyond a wonderful job on her facials. A great experience all around!

I started going to OptimalSelf MD while still recovering from COVID symptoms. I was 2 months after exposure and still feeling terrible. I needed my life back and Dr Katherine had the right combination of vitamin and immune booster infusions to help me in this process. After I was feeling almost back to normal, I decided to go for her full spectrum review of systems to see what else I needed to target to improve my overall health and well-being. I was amazed by the results! I knew exactly what my body was lacking for proper digestive health and hormone balance. She didn’t just put me on medications to “see if you feel better”. She had the data to show exactly what my body needed to function optimally. I’ve lost 10 lbs so far and have more energy than I’ve had in years! Plus her and her staff are amazing to work with! They treat you like they are your BFF, on top of being super professional and informative. They are there for you whenever you have questions along the way and don’t make you ever feel like you’re a bother. Good health is a life commitment and I’m glad I have found an amazing team to keep me on the right track.

I started seeing Dr. Katherine Birchenough after several people recommended her. I had been struggling with daytime fatigue for years. Even though I was trying this functional medicine I was extremely skeptical. Years of different strategies, doctors, voodoo hadnt helped. Dr. Katherine takes a very thorough history and blood work. Shes like a detective with a mystery. Well, Sherlock Holmes has competition! I feel so much better. I have energy during the day and feel good and strong. I cant explain how she does it but it works!

Always make me feel welcome, Dr Shawn Birchenough always professional but with a human touch. I really recommend is practice.

Everyone is very nice and so helpful. Dr. K is fantastic !

Dr. Katherine and staff are wonderful. Caring and friendly and knowledgable, they take time to listen and look at the whole picture. I have recommended her to others and will continue!

Always professional, on time, attentive and personable. Brandy is one of THE best and I highly recommend this practice!

Really friendly and knowledgeable staff! I learned a lot on my consultation. Can’t wait to schedule my next appointment.

Very knowledgeable and friendly. Always feel that my needs are important. Definitely recommend!!!

An amazingly beautiful team. Dr. Shaun and Dr. Katherine are experts beyond words. Great ! Great! Great !!!!!!

Knowledgeable and friendly staff. I highly recommend.

I met Dr. Katherine as she has treated my wifes thyroid and hormone conditions. I decided to have an evaluation due to my consistent weight gain to determine if I had a thyroid issue developing. Dr. Katherine spent a lot of time reviewing my medical history and also did a deep dive into my food consumption, lifestyle/activities etc.... Extensive blood work followed and the answer was clear. I was taking in too many carbs. Dr Katherine organized a carb detox for me and then transitioned me to building a food plan on my on based on how my body responded to different levels of carb intake. She didnt give a fixed program, but rather the tools that allowed me to succeed for the long term. Along the way, she methodically treated my low testosterone levels. The combination of eating, exercising and improved hormone levels have led to a 45 lb weight loss and incredible energy improvements. I sleep much better, my mind is less foggy and my overall outlook has improved as my health has improved. Dr. Katherine continues to monitor my bloodwork and offers advice along the way to help me continue to improve my health. I value the personalized treatment approach and the time she invests in understanding her patients.

Eliza and the rest of the staff were nothing short of amazing! Best in Greenville without a doubt!

I started seeing Dr. Katherine last year, to help with my horrid sleep disorder. She did a thorough lab workup, the most thorough I have ever seen, and Im an RN for many years...She determined through genetic testing that I had indeed been born with this disorder, and we began work to improve my sleep and make me feel generally better...I am happy to say that I am now sleeping well most nights, and with 1/4 the dose of medicine I had been on for years. Im very happy with the results of my consultation, and Dr. Katherines ability to work with me to solve my issues.

Everyone at Optimal Self MD is fabulous!!

I usually do not take the time to do this but I feel I must. I begin seeing with Dr. Birchenough exactly a year ago. I went through her extensive testing and she prescribed me a treatment plan in March for the diagnosis she came to. It did not go well and after declining I was tested specifically for the condition in June to confirm her diagnosis. It turned out to be incorrect so I was being treated exactly opposite of what I should have been. I was given a new treatment plan. The short version is I never heard back regarding our follow up and when I finally contacted her she told me I would be better off finding another doctor who was more familiar with my condition. I asked for a referral and she gave me the name of another FM that practiced online. My advice is that if you are truly interested in having a professional help you get to the root of a health issue you should go elsewhere. If you are interested in aesthetics then as the description says now plastic surgeon in Greenville this might be the place. Very disappointed in a wasted year and on the search for practice that is truly devoted to Functional Medicine and helping them reach optimal health.

Wonderful experience and staff

Dr. Katherine Birchenough is an outstanding physician. She is at the forefront of medicine with a holistic and integrative approach. She focuses on the root cause of disease. As a doctor myself, I trust her with my own care and would happily recommend her to friends, family, and patients.

I have nothing but positive things to say about the entire team at Optimal Self. I came to them with an odd set of symptoms, and Dr. Birchenough has been working with me to resolve them, using her out-of-the-box thinking skills in combination with her medical prowess. Unlike many other doctors I have seen, she always listens intently, demonstrates curiosity, and leaves no stone unturned.The office staff (and Dr. Birchenough herself) is quick to respond to my emails, phone calls, and requests. Ive never been to a doctors office that is as responsive as this one.Functional medicine practitioners can be hit or miss, sometimes promoting quackery and pseudoscience. Dr. Birchenough, having practiced traditional medicine for many years, seems to have the perfect balance of the two worlds. Not afraid to prescribe real drugs when necessary, but also not afraid to try more experimental methods to find her patients a solution.I cannot recommend a doctor more highly than I recommend Katherine Birchenough and her team.

I was first a patient of Dr. Katherine Birchenough several years ago when I was at a very low point healthwise with no insight into what was causing me to feel so terrible. She ran a battery of tests that demonstrated her thinking outside of the box approach to patient care. After seeing her, I experienced much improvement and gained valuable insight into the root cause of my issues. I highly recommend a consultation with her, especially if you have not received answers anywhere else. Today, her office downtown offers many services, including IV vitamin therapy, that help keep her clients in optimal health. Dr. B and her staff are truly a pleasure to work with.

I cant say enough about the care that Dr. Katherine has given me - after 3 1/2 years and 11 other doctors, she took the time and interest needed to put me back on the road to good health. Her knowledge and intellectual curiosity combined with her care and patience are a gift to her patients. And, she surrounds herself with an equally kind and helpful staff - every visit is a positive experience!

I went to Dr Shaun for a tummy tuck and some liposuction, The staff and Dr Shaun explain everything and listen to your concerns. I would recommend going to see them for a consultation on any procedure you are wanting to have or just curious about. I am now 3 months post op and the results are amazing.

I went yesterday for a vitamin infusion after feeling sickly for a few days, and was really impressed. The registration process and the treatment were both quick and efficient. The entire team and Dr. Katherine we’re all incredibly kind and explained every step and exactly what I would be feeling. I’m now refreshed, have way more energy and slept like a baby. I’ll definitely be back, and recommend both this practice and the treatment!

Our 3.5-year-old had daily tummy problems and a weak immune system after overprescription of antibiotics by her pediatricians. Dr. Katherine identified the correct tests to run, response to the test results, and maintenance regime. Within a few months our girl was free of all tummy ache and other symptoms, and has never been healthier! Dr. Katherine is very knowledgeable, thorough, and pleasant to work with. I recommend her to anyone looking for a good functional doctor or help with their health issues in general.

Dr Katherine is transforming Healthcare in the Upstate. She is a brilliant doctor who focuses on root cause and developing an individualize care plan each client! Finding Dr Katherine and the Optimal Self team has truly been life changing for me as an autoimmune challenged person. I am able to live Optimally!

Got a breast augmentation a little over a month ago. Everything went great from the surgery to the healing. And the staff is awesome also. Would highly recommend!

After many months of profound medical issues that no other doctor could resolve, I met with Dr. Kathrine. After a thorough review of my condition and many tests, she provided treatment and medications which allow me to now say, I cant remember ever feeling this good.

I had the pleasure of meeting Dr. Katherine Birchenough during my search for a new Wellness/Health care provider and she introduced me to the NAD+/Brain Refuel treatments and the results are amazing, almost immediate. I was particularly interested in overhaul brain health, staying sharp when business travel and other engagements require being 100% on point! Thanks Dr. B!

Dr. Shawn went above and beyond during my appointment. He and his nurse Jenn put me at ease and made sure I was comfortable during my procedure. I would highly recommend going to see him!

I really find the experience to be sensational because I am listened to and solutions are looked at, not just treating my symptoms. I know my body and I know what is coming out as a symptom. Dr. Birchenough knows medicine, alternative medicines and testing, which gives me confidence I am getting to the bottom of my healths solutions.

Frequent visitor for their BrainRefuel (NAD) treatment. The IV therapy itself is nothing short of a miracle. Increased energy, focus, mindset and noticeable mood enhancement. Ive found myself back in the office every couple months for a top off! The office environment is incredibly welcoming. Absolute professionals, Dr. Birchenough is second to none in her craft. You wont be disappointed in the treatment, or their first class service!

I had a breast augmentation and it couldn’t have gone any better than it did. Prior to surgery date, a couple of issues arose but the staff and Dr. Birchenough went above and beyond to make sure everything was ok with me. They went out of their way to accommodate me. I recommend Optimal self MD to everyone. Dr Birchenough and his staff are the best. Jenn was awesome ! I’m so glad I chose to go with this facility !!!!

I travel from Columbia to see Dr Katherine Birchenough. (1 ½ hours) I dont know of another doctor or office like hers. She tests far beyond the scope of regular MDs and has a vast knowledge. She and her staff are very attentive and cheerful & take time with you. Ive never been to a relaxing doctors office, but hers is just that. They dont treat you like a number or a time slot... HIGHLY recommended!

Oh my gosh - I am so grateful that I found Dr Shawn and his staff. They are all fabulous, and have taken wonderful care of me. After years of wanting to get a breast lift, I had done all the research under the sun. When I finally made the decision to go ahead with it, I researched the top local providers, and made an appointment with OptimalSelf MD for a consultation. After meeting with them, I went home and cancelled my other consultations. I had already found the one and I didnt want to waste anyone elses time.Dr. Birchenough and Jenn, his nurse, walked me through the options and talked to me about the possibilities. Then they generated the Crisalix 3D image so I could see what the results would be, and let my husband take a look since he wasnt able to join me for the consultation. I had some initial hesitation about the size because I have a small frame. So they created more images for me to look at so I could make the right decision.What I remember from the day of surgery was great - the hospital staff was wonderful and kept me informed throughout the pre-op. My husband said they were all fantastic afterwards as well. The next day was my first post-op, and I was so happy with the initial results.Im just about 4 weeks post-op, and my breasts are healing beautifully and looking better than I could have imagined. I am feeling good and almost back to my complete normal routine, less lifting heavy weights and running.Ive also since had some fillers at OptimalSelf, and again am so happy with the results.Everyone at OptimalSelf takes amazing care of their patients and treats them like part of the family. I cant fully express my gratitude for the way theyve made me feel, not only about myself, but about the entire process.

OptimalSelf helped me figure out what was wrong with my health efficiently and maintain my healthy state after treatment. They were super helpful with answering questions in appointments, sending me information throughout different stages of treatment, and even after I finished their program. Their staff is extremely personable too and sent me tips and support along my journey back to feeling well again!

Wonderful staff !

Cannot say enough good things about the entire team at this office. They are understanding, friendly and compassionate. They help you look and feel your best with all the varying products and services they offer.
