Hello, I’m Jack Siebers, an advanced practice nurse practitioner for Affinity Medical Group. I provide personalized care to patients of all ages. I have a special interest in managing acute and chronic illnesses, as well as men’s health and wellness. With more than 20 years of inpatient experience in the intensive care unit and general and cardiac surgery, I appreciate the opportunity to provide preventive care. My goal is to establish relationships with my patients and their families, and help them enjoy optimal health throughout their lifetime.

Outside of the office I enjoy spending time with my wife and kids, hiking and camping, and biking.
