Patient Testimonials

2013 99th Percentile Patient Satisfaction

“Dr Thomas is thorough and innovative in his approach to women’s health issues. I am impressed by his enthusiasm for improving and enhancing our quality of life regardless of age! Additionally, his staff is pleasant, helpful, and very efficient.”
Susan Shulman
“I have been using HRT pellets for about 3 years and it is the best decision I could have made. I was told I should not use this form of treatment, but trying to have a normal sex life and life generally was becoming increasingly more difficult and painful. I felt horrible and really old… I had no energy and my intimate life with my husband was suffering where it had been amazing before. I was beyond miserable. I finally decided to try the pellets and as soon as my hormone levels started becoming the way they used to be, I became the person I used to be.
Now I have energy and desire. I am pain free and my osteoporosis is also being reversed. It is the best decision I could have made. I have my life back in every way and that is priceless! I am so happy I did not listen to those who said I shouldn’t and wish I had done it sooner. I never want to be without my pellets again. My wish is the insurance industry would pay for them because, in the long run, it would save them money by keeping us happier and healthier both physically and emotionally. This is such a life-saving, simple way to be healthy and whole. You have nothing to lose and everything to gain by trying HRT.”
Debbie Singer
“I had to change doctor’s after the birth of my first child when my OB-GYN of more than 10 years retired. Dr Thomas just delivered my second child, and I could not have been more pleased with the experience. The pregnancy was a little complicated with my being of advanced maternal age and having preeclampsia with my first one, by Dr Thomas managed my gestational hypertension and prevented the preeclampsia from returning this time. He is very friendly and professional and always has the research to back up the answers he gives you to any questions you ask.”
Jennifer Ortiz

“I came to Dr. Thomas today for estrogen pellets I take every 3 months ever since the age of 39. Dr. Thomas did a great job inserting these pellets, no pain, or any other side effect. It has been a half hour since these pellets have been given to me and already I am feeling their effects of cooler body temperature, concentration, and alertness.”
