His goal is to restore optimal health and prevent disease before it becomes symptomatic. He has developed an annual health plan that walks patients step-by-step through the healing process over an entire year.

Each patient receives a customized health plan designed to restore the body’s natural hormones to levels they had when they were 20 years old.

In addition, each patient receives a customized nutrition plan based on their specific physiology, biochemistry, and nutritional status. Lastly, he uses the latest scientific technology based on peer reviewed medical literature to help patients break free of the current medical model which is treating symptoms with drugs while failing to address the underlying or root cause of the disease.

Bioidentical Hormone Replacement Therapy Success Stories

Three years ago I met Dr. Breen at a seminar provided by my gym.  He gave an insightful presentation on how hormones, eating correctly, and taking the right supplements can play a huge role in your fitness goals.  I first sent my husband to see Dr. Breen due to his lack of energy and general issues associated with being in your late 40’s.  His General Practitioner told him that all of his levels were “normal.”  Personally, I don’t think being on the low end of the spectrum is considered normal.  His overall health and stamina is amazing since becoming a patient.

After seeing the positive changes in my husband, I too decided I would get checked out my Dr. Breen.  After discovering some thyroid issues, my energy, physical performance, and leanness are where they should be.  Dr. Breen’s personal program has helped me to make gains in the gym (I’m a cross-fitter), help me with my eating habits, and my overall health.

Dr. Breen has an amazing bedside manner.  He actually listens when you talk to him, he remembers things you’ve said in past appointments, and genuinely cares about your health.  His goal is to have each of their patients at their optimum levels.

Regardless of your age (I’m 34 and my husband is 50) – Dr. Breen can help to fine tune your health goals.  My husband and I are both in the best shapes of our lives, physically and internally, and that’s all thanks to Dr. Breen. -Christie C.

This review is long overdue. I’ve been seeing Dr. Breen just under a year and I wanted to wait until I had been under his care long enough to give a full review. When I came to Dr. Breen I had low energy, was extremely overweight and just felt horrible. After a comprehensive battery of blood tests and over a two hour review with the doctor I was devastated at how I had let myself go. Based on the tests I was well on my way to an early heart attack. I’m not even 35 yet, so needless to say it was extremely scary to hear that I was in such poor health.

Dr. Breen immediately told me what I needed to do to get back to a healthy weight and lower my risk of a heart attack. He put me on a bunch of supplements, got my hormone levels in check and gave me a nutrition and exercise plan that has worked beyond my expectations! It’s been less than a year and I feel like a brand new person, I have energy to play with my kids and I feel great. I’ve lost over 50 pounds and can now wear a size 30 waist! I went from over 40 percent body fat down to 13 percent! When I had questions for the doctor he was always accessible and even lets you text him on his personal cell after hours. This is true concierge service. I can’t thank Dr. Breen and his team enough for all they have done for me. My wife was so thrilled will my results she has now gone to see him as well. Thanks Dr. Breen for giving me my life back! –Jamie M.

Dr Breen has a very specialized practice.  To get a doctor who thinks outside of the box and who is personally avalable to you 24/7 it can be expected to pay a little more. Also insurance fails to cover preventative and anti aging type of care. I am an RN and personally have been in dr breen’s program and have had excellent results. I look and feel better and I am very thankful for doctors like Dr Breen.

If you’re having issues with hormone balance or weight gain or really any type of health issue it would certainly be worth giving Dr. Breen a try. –Vincent C.
