I can’t thank Dr.Fontaine enough! Menopause is certainly a subject that is not talked about enough it changes lives and for some it destroys them. I was at a point in my life during menopause where I was ready to die, that’s how bad I felt, only six weeks later after Dr Fontaines program based on MY blood, MY hormones! Not a generalized version for every woman! 🤬WTF is that? I feel better than I have since 2017 which is when I began menopause. Why menopause is not talked about and not covered by insurance for this kind of treatment is beyond my comprehension but I am grateful for people like Dr. Fontaine and his staff! Life changer. If you are on the fence, do it!!!

Okay so I have been doing Botox and fillers for years. I have never considered doing fillers for my under eyes as I was always nervous to. But naturally with age things have started to droop. Finally I decided to bite the bullet and go in for a consultation. I met nurse Sam and after a detailed consultation I felt enough confidence to jump forward with the treatment. Sam made the entire experience fun, comfortable and educational. Not to mention the results are EXCEPTIONAL. I was afraid of looking fake or overfilled which Sam ensured me that I would not and that I would only look refreshed. Everything she said from the start to finish of what I should expect was on point! Her skill level of technique was so advanced and she made the treatment easy. I couldn’t be happier with my results and my overall experience. Sam isn’t just a nurse, she becomes your friend who will make you look and feel your best. Can’t wait for her to treat me again.

Dr. Fontaine has been amazing! I have seen several similar doctors in his field prior to seeing Dr. Fontaine, he is by far the best. I highly recommend Dr. Fontaine and his staff is also very professional and knowledgeable. Two Thumbs Up!!

Dealing with Hypothyroidism in my mid 20's took a toll trying to figure out the right medication/Dr. to actually listen to what was really going on. Dr. Fontaine took that stress off my shoulders by being efficient and knowing all the accurate tests to take. With that knowledge he was able to get me on the right regimen and my hormone levels balanced again. I was looking for a Dr. I knew would understand me and not impossible to get a hold of if something felt off. Wether it's a direct text or a phone call, one of my favorite things about this office is knowing my question will be answered without any hassle or wasted time/money.

Dr Fontaine and his entire staff are fantastic to work with. Everyone is helpful, respects your time but you’re never rushed either. They’re thorough too. My husband and I both see Dr Fontaine and I saw Megan today for Botox. She’s amazing!
