How much does concierge medicine cost?
Each patient has individual needs. In order to better understand how our concierge medicine program works and what services you plan to utilize, we offer a complimentary consultation with one of our providers.
What is included with my membership fee?
The membership fee provides you with direct access to your provider beyond typical office hours which allows for a more personalized approach. You will also have access to our specialized programs and services such as our weight management program, IV infusions, and hormone therapy, as well as special pricing on aesthetic services.
Do I need insurance?
We strongly recommend that you continue to retain your traditional healthcare insurance in order to help pay for diagnostic imaging, medications, hospitalizations, specialists, and any medically necessary services. You will still be responsible for any co-insurance, co-payments, or deductibles as dictated by your healthcare insurance provider.
