I'm not a big 'testimonial' type guy, but when it's deserved, it's deserved. Dr. Bartnof not only helped me 100% with my Low T issues but he also take care of my primary care issues too (flu, and low back pain). There's almost NO wait time and he really get how men like to be treated in a doctor's office. Staff is efficient and friendly and they actually pay attention to what you tell them. Great office, Great staff, Great outcomes. I feel great.

I started the program with Dr. Bartnof immediately. It took me approx. 3 weeks until I saw the first good results. After 4 weeks on this bio-identical hormone replacement therapy I was literally a new person. I was happy again, I was able to sleep like a normal person, I resumed my workout routine, which I had given up three months ago, my hair has improved its texture and looked healthier, I could control my cravings and I even started losing weight. In a word, it was amazing. I have become the person I always wanted to be. His office in 450 Sutter Street, San Francisco, CA was also clean and made me comfortable. Recommend to anyone.

The whole office is very courteous and professional. Dr. Bartnof is an excellent 'Low T' doctor in San Francisco, CA and he is very supportive to his patients - a breath of fresh air. I like the friendliness of the staff, the professionalism of Dr. Bartnof and the promptness with regard to communications. I like the fact that a phone call, text or email is usually replied after leaving a message.

I felt very comfortable with my consultation with Dr. Bartnof although I had a lot of questions going into it. I had a little bit of nerves before my Testosterone Deficiency procedure, but was pleased with the results. I will definitely go back to his office at 450 Sutter Street, San Francisco, CA! Thanks again.

I came here for some help with age management and all the fun stuff that comes with it, I did appreciate the upbeat attitude of the staff and how friendly they were. I've been to too many doctors offices where the staff was less than cordial, its a relief to come to a happier place.



Dr. Bartnof has been great, he's seldom late for appointments, has a good bedside manner, and is always good about squeezing me in for an appointment when I need to come in.

I came here after my sister recommend their menopause treatment - and it's worked very, very well for me. I'm not having as severe of hot flashes and am feeling less fatigued overall, very glad I took her advice.
