Dr. Kathryn Retzler - Contributing Physician

HormoneSynergy Clinic

Dr. Kathryn Retzler

The purpose of my life is to inspire millions of people to achieve vibrant health and longevity and to help prevent as many cases of premature death as possible. I believe every person has a unique path to vibrant health, and that optimal aging and healthy brain function are possible for everyone. I believe the more people I influence, the more precious, quality time they'll have to fulfill their purpose and to experience the joys and blessings of the world.

I believe many people settle for a negative definition of aging. I do not accept that aging means falling apart on schedule. I have a high standard for my physical, mental, and spiritual health, improving every year. I hold the same vision for my patients.

The tools I use to fulfill my purpose include sharing knowledge, providing authentic leadership, offering successful treatments, and continually improving my skills and education. I am grateful for my work, and committed to fulfilling my purpose.



I received my doctorate from the National College of Naturopathic Medicine in Portland, Oregon in 2001. After completing an internship in integrative medicine with Andrew Weil MD, and a residency in McMinnville, OR with Dr. Bruce Dickson, I decided to focus my enthusiasm, talents, and knowledge in building bridges between conventional and alternative medicine.

I founded HormoneSynergy® Clinic LLC to help people achieve vibrant health, ideal brain function, and longevity. As a specialist in holistic medicine, I understand the role balanced hormones and neurotransmitters play in all areas of health. I completed a fellowship in preventive cardiology through the American Academy of Anti-Aging Medicine with Mark Houston, MD and I attend several age management and brain health seminars and conferences yearly, with gratitude to the mentors who've influenced my work--Rebecca Glaser, MD, Thierry Hertoghe, MD, Daniel Amen, MD, and Dale Bredesen MD, (Bredesen Protocol).

I recommend effective, evidence based natural therapies, lifestyle changes, and bioidentical hormones to address the underlying causes of hormone imbalance and restore health and vitality.

"Let me help you write a new life story!"

Each of us has a story about our life. It is continuously being written by our underlying beliefs, assumptions, and experiences. The story we write about our life defines us in the present and guides us toward our future. It either supports us or diminishes us.

Growth and change begins when you accept personal story ownership: the recognition that you are the author of your own story. You can change your story at any time. When you change your story you will change your life. I can help you write the story about the life you want to have.

I am a counselor and certified spiritual and life coach. I love to motivate, inspire, and influence others to make positive change in their lives. I am passionate about life and learning. I'll use my passion for life, my skills and my own experience to help you navigate the gap between where you are and where you want to be, achieving the positive change you desire.

In addition to spending time with my family, I enjoy regular exercise, running half marathons, biking, movies, and coastal getaways. Together with Dr. Retzler, I am committed to providing you the opportunity to change your life employing my passion, education, skills, and ever expanding personal experience.

I am the owner of this store and HormoneSynergy® Inc. and am solely responsible for all content.
