Anti-Aging Medicine - Adam Leid D.O.

My purpose: Feel your best, look your best and perform at your best.

Sick care is the current state of medicine. We wait for symptoms to develop before we address them. Rarely any more do we concern ourselves with the origin of the underlying issue. Our mindset needs to change. Prevention is the key to increasing our healthspan – no one wants to live longer if they are unable to do the things they enjoy. Quality of life is, and should be, our focus. It is currently not possible with the current fee for service model to develop prevention strategies. The 15 min visit that you waited months for with your primary physician are solely useful for acute issues and medication management. Reinvest that monthly medical insurance premium into preventative health and allow me to help you live your best life.  My practice at Core clinic compliments the total wellness opportunities available to our patients.  It's the best of the Main Line!
