What patients are saying
- Linda Tighea month ago
Credit for my good health over these last 25yrs plus largely belongs to Dr Retzler. Not only did she advise and explain the benefits of HRT at a time when it was still controversial but she asked questions and diagnosed a condition that my PC doctor never addressed. She listens and meets me where I am regarding diet and exercise. Allowing patients to spend the concierge’s fee to purchase supplements is a win win. I feel supported in every way. The blood panel she runs is far more detailed and informative than any I’ve gotten elsewhere. Everyone at Hormone Synergy is helpful and kind.

Helpful, friendly and competent staff. Dr.R is very knowledgeable and up to date with latest research, developments and health management strategies. Blood work tests are comprehensive and complete to determine health status on my body recognizing any vitamin deficiencies and imbalances. Appropriate recommendations are made concerning supplements and dietary modifications to regulate body physiology as well as life style changes necessary to insure good health. The blood work up and results are sent to my medical internist who then integrates the results in my permanent medical chart at the hospital. It amuses me that the internist marvels at the extent of the blood work that I receive at Hormone Synergy and confesses that my annual Medicare check up is no where near as comprehensive as the testing I get from my Naturopath physician. When it comes to my personal health I am extremely proactive in getting the help and care from those who offer it. Any I’m extremely grateful to have Hormone Synergy and Dr.R monitoring my health and well being.

Dr Kathryn Retzler is such a joy to work with. She brings a science based approach to healthspan for her patients. Her ability to make it understandable for the layperson puts you at ease. Her caring manner makes you feel like you have an advocate for your health journey.

I had a follow-up appointment today to review Blood Test Results. Dr. Retzler reviewed & explained my test results in detail and advised recommended prescription changes. Because I mentioned some weight gain, she immediately performed a SECA Body Composition Test (in the office) to check my current Fat and Muscle Mass. She was very thorough and clear. I strongly recommend her clinic for proactive health care.
