Our Philosophy:
We seek to promote wellness and vitality for our patients through a Holistic approach.  Rather than reaching for a prescription during a short visit, our focus is on taking the time to help make changes in lifestyle which will address the core reasons for poor health.  By having people buy into the fact that our choices and environment impact our well being, we establish a partnership in implementing solutions together.  By combining the fundamental aspects of traditional medicine as well as alternative medicine We are able to treat our patients in a comprehensive way.
We’ve established a practice where patients can come, without judgement, for counseling and guidance.

Personal Interests:
Avid Yoga practitioner for the past 12 years. I enjoy all outdoor activities, especially hiking and all water activities. I enjoy leisure time with my children and grandchildren, and look forward to a little travel in my near future.

Philosophy Regarding Health:
After 35 Years of practice, I have come to understand that as we age, the key to optimal health is in creating balance. We create balance in how we choose to eat, how we move, what we emotionally fill ourselves with and how we generate sleep. Our bodies are unique, as they come with all the necessary internal capabilities to regenerate and self heal. We need to honor our bodies with the choices that we make and how we choose to view ourselves. This concept continues to inspire my practice of medicine. It is no longer all about treating chronic illness, but the promotion of prevention of chronic illness. I find satisfaction with inspiring and partnering with my patients on a path of wellness. We have the technology to to extend life, but not necessarily to improve the QUALITY of that life. That is about the choices that you make along the way.

When it comes to aging, the only choices are to accept deterioration or choose restoration. I have chosen restoration. In addition to lifestyle balance, I promote hormonal balance. Hormones regulate our body heat, and ability to think and feel good; hormones keep our bones strong, our brains sharp and our organs functioning. Hormones are what give us our good health and the symptoms we associate with aging are often simply related to this decline in hormones. I look forward to working with the patient who is highly motivated and and filled with the expectations of achieving optimal wellness.

Philosophy Regarding Heath:

My philosophy regarding health stems from my long history of competitive athletics. The medical provider acts as the coach and the patient as the athlete. It is the patient who is in the driver’s seat. We strive to provide the most comprehensive and quality health care but it is ultimately the patient who must take personal responsibility to getting well by making good life style choices thru diet and exercise, weight management, taking medications as prescribed, and focusing on wellness rather than disease.

Philosophy Regarding Health:

I am a strong proponent of holistic and individualized care. I believe in the integration of evidence-based medical practices with adjunctive complimentary therapies based on an individual’s medical and psychosocial background, expectations, and needs. Achieving wellness is finding the intersection and balance in the realms of being: psychosocial, physical, mental, and spiritual. My goal is to partner with patients to investigate the potential dysequilibrium within these realms of being and henceforth provide individualized education, diagnostics, therapeutics, and follow up. I encourage patients to view the provider/patient interaction as part of a long term relationship contributing to excellent continuity and quality of care.
