About David A. Chappell

From the time I was a young boy I knew I wanted to follow in my father’s footsteps and become a doctor. When I was 5 years old, I went to India with my family on a medical mission. During that visit, I vividly remember playing the role of a doctor in a skit. The first moment I put a stethoscope around my neck I realized that being a physician and helping people was my calling. My father taught me from an early age that “More things are missed by not looking than by not knowing.” His words have guided me…helping me to always delve deeper into my patients’ healthcare issues, well beyond endocrine concerns.

Unfortunately, the medical landscape has changed in recent years. Doctors are rewarded for speed and technology, not “looking,” listening and thinking compassionately. This trend has threatened my ability to provide you, my patient, with the highest quality of care.

The time we spend together is fundamental to our doctor-patient relationship. I am committed to spending all the time needed and working until the day is done to make a more targeted diagnosis or determine a course of action…I refuse to compromise this standard.

In 2014, I decided to enhance my endocrinology practice by establishing a personalized primary care medical practice, which has allowed me to care for each patient as a whole person without limitation. In my concierge medicine practice, I have more time to spend with you and focus on all of your medical needs in a comprehensive manner. I have the opportunity not only to be reactive when you need medical attention, but also to be proactive in preventive healthcare to keep you feeling your best.

It has been a fulfilling and exciting chapter in my professional career! It would be my privilege to be your personal physician for many years to come.
