Dr. Karl’s Team-Based Care Approach


Dr. Karl partners with three advanced practice providers — Tiffany Nobles, FNP; Stephanie Bond, DNP, FNP; and Isabel Johnson, PA-C — to provide coordinated, personalized care. Each patient is assigned to one of these providers and to Dr. Karl as a shared team, where they collaborate in all aspects of the patient’s care. Each patient visit starts with the advanced provider, who is qualified to order testing, make medical recommendations, and prescribe medications. Dr. Karl will join the visit for complex medical issues, additional questions, or simply when a patient would like to say “Hello!”

This approach allows two dedicated providers to work together for your health, ensuring excellent access, close attention, and continuity of medical care.
