Aesthetic Gynecology

One of the fastest growing segments of cosmetic surgery is female genital surgery. Many phrases are used to describe what is surgically done, and the catch-all phrase lay people have seen with increasing regularity is “vaginal rejuvenation.” In reality, vaginal rejuvenation is a marketing term referring to vaginoplasty or the surgical tightening of the vagina.

Patient Testimonials

Ladies please take the time to read this testimonial. I believe you may possibly arrive at the conclusion that HRT may be just the solution you never knew you needed. As we age, our hormone productions slow down, so we chalk it up to age being the cause for not feeling vital, youthful and vibrant. We have been conditioned to view this as “Nature Taking Its Course”, and that “hot flashes”, night sweats, highs and lows in how we’re feeling each day, is all a part of being a woman.

It doesn’t have to be this way, but too many doctors prescribe Premarin pills or an anti depressant to mask the highs and lows, and this is not the solution to raise the levels of hormone that your particular body needs. Hormones are not a one size fits all, how can they know what will work for you? They don’t, that’s just it but they’re out there, and despite the confidence you may have in your doctor, it takes a specialist to ensure you’re receiving the proper levels.

If you could improve your Sense of Well Being, the quality of your life and push out the signs of aging, would you do it? Imagine that with changing how “you feel” the ripple effect it will have on the people around you, your job, getting off your duff and going to the gym because you now have the energy to get back in the race.

People never guess my age, in fact, they guess me to be 15 – 20 years younger. You can judge for yourself when you look at the photo. I have a beaming smile, I’m proud and happy to be 63, sitting in race car getting ready to drive at 150 mph. This isn’t for every woman but I’m sure there are things you used to do and enjoy, and have substituted it for reading a book, watching TV or watching the grandkids. Why not ride your bike with your grandchildren!

Can you imagine that there are over 72,000 people living at ages over 100? Dr. Thomas can explain the bio-identical aspect of HRT to you. These are hormones that your body used to make on its own but age slows their production, and you can be out of balance. You can defy Mother Nature and push out your aging with benefits for: your bones, skin, hair, teeth, the list is a long one. I’m not going to steal Dr. Nathan Thomas’s thunder, he will explain the process and answer your questions on a level so that you can understand and relate to his explanation.

I know that there are many women out there that would give a similar testimonial. It’s you’re life, and the older you get the faster time seems to pass. Be in a better place NOW, and don’t look back wishing you had taken the steps to retard the aging process. If I were you, I wouldn’t walk, I’d run to schedule an appointment for your consultation.

Have a stellar life

“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.”

“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.”

“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.”
“I appreciate that Dr Thomas allowed me the time to ask all of my questions and concerns and was very patient with me. His staff is friendly and the office appeared clean & organized. I will be happy to refer my friends to him.”

“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.”
