Derek Heldzinger , MD

My commitment is to educate my patients about their health while optimizing wellness to prevent illness and chronic disease.

Dr. Heldzinger earned his medical degree from the University of Stellenbosch Faculty of Medicine and Health Sciences in Cape Town, South Africa. After finishing medical school, he became board-certified by the American College of Lifestyle Medicine.

In his over 30 years in medicine, he kept seeing a need for a medical practice that would support health, provide lifestyle options for prevention, and lead patients in making changes that would benefit them in the long run.

Lifestyle medicine was the answer. Every day the team works with patients to help them follow a healthy diet, get sufficient exercise and sleep, and maintain a healthy body weight to prevent chronic disease.
