Dr. Fontaine is my hero! I've been seeing Dr. Fontaine for a few years. Through his exceptional care, I went from being post menopausal, low energy, overweight, and irritable, back to being a much healthier, happier and productive version of myself. As a incredible bonus, due to Dr. Fontaine's catching a kidney function issue on my bloodwork, and finally impressing upon me the importance of following up on the issue, we found a huge, previously unknown kidney stone blocking my kidney and I ended up at Kaiser having emergency surgery, which saved my kidney. Needless to say, Dr. Fontaine is an exceptional medical care provider and I'm very lucky to be his patient.

I have received botox for a long time. Most recently I stayed at Fontaine MD when Sarah came on board: Never have I had a more professional, warm, friendly, and kind person, Sarah, treat these awful lines all over my face and turn me into something so much more stunning. We are working together to do a laser treatment soon and I cannot wait. Sarah is just the best, and I can't recommend her more highly. My life is better now that she's helping make me feel good about myself. Thanks Sarah and the team at Fontaine <3

I had a great experience with nurse Louise. I received a medical grade facial and skincare regimen. The facial was relaxing and my skin felt so smooth after. I purchased Zo skin health exfoliating polish which is a game changer along with redness reducing rozatrol and Alastin sunscreen that makes my face look flawless. Louise was so kind and attentive to my concerns. I will definitely be back to see her soon.

I came to Dr Fontaine about 2 years ago, exhausted after fighting with my PCP about my thyroid levels. I was really needing someone who was able to listen to me about how awful I was feeling and to help me through the next stage in my life. Not only did Dr Fontaine listen but also provide tailored care specific to my needs. I cannot emphasize how much he has improved my quality of life helping me not only with my thyroid levels but also with my peri-menopausal symptoms. I now can sleep through the night, got rid of my bloat, and significantly decreased any hormonal side effects of this delicate stage. He has made my life so much more vibrant and full of energy! I highly recommend him to anyone interested in wanting to optimize their health so that their next stage can be the best it can be!! Thank you Dr Fontaine and all of your amazing & kind staff!!

Is there a 10-star rating?! Working with Dr. Fontaine has changed my life. I'm a 47-year old woman in the throes of peri-menopause. At the time of my first appointment I was desperate for help and to be heard. My emotions, moods and energy levels had bottomed out, I was having hot flashes and extreme night sweats, was experiencing insane fluctuations in weight and bloating and generally just felt like an alien had taken over my body and mind. Counsel from my primary care physician (a woman! In her 50s!) was "Welcome to your mid-40s" and "maybe consider going back on birth control to level out your hormones." It was RIDICULOUS! I was so frustrated and disheartened. I began reading/learning more about bio-identical HRT and felt like I had nothing to lose by trying it. Enter Dr. Fontaine and his amazing team!! My first appointment + discussion with Dr. Fontaine was 90 minutes and super fruitful. To hear him say "you're not crazy, this is real" was so affirming! After a lot of dialogue and reviewing bloodwork he recommended a treatment plan of a change in my Thyroid medication (which was so, so poorly prescribed. He was like "I don't know who put you on this in the first place, and why different doctors over the years have just blindly renewed it, but this dosage is doing you more harm than good") and then a regimen of testosterone and progesterone as well as a couple additional supplements for minerals/vitamins I was low in. Within the first 14 days I felt like a new person. The hot flashes and night sweats were the first thing to improve and that alone changed everything! Over the next couple of weeks my energy, sleep, moods and weight became more consistent. It's been 6 months now and I feel like I have reclaimed my life. I can't say I'm peri-menopause-symptom-free (new stuff pops up all the time that is confusing... period-symptoms but no period for months, fluctuating energy and fatigue that mimics a menstruation cycle but without menstruation, mid-life blues, blah blah) but I can say that I feel 150% better than I did when I started. Run - don't walk - to Dr. Fontaine!
