Jami Dybik

Practice Manager

Jami has worked in healthcare since 1997 and she has come to believe the best healthcare comes from a meaningful partnership between a primary care practice and the patient. Primary care is essential to overall health and wellness and loves that Truesdale Medical Center is a driving force in 21st century healthcare.

Being a patient herself, she has a deep appreciation for the value of having an advocate in the healthcare system. She genuinely enjoys working with patients and being able to help them attain their best health. When people walk through the doors, Jami and her team strive to make them feel comfortable in an environment that is not always on people’s list of top favorite places to be. Overall, patient experience is extremely important to her and remains her main focus in the practice. That includes from the time patients step into the waiting area to the time they leave the checkout desk. Jami is incredibly proud to be a part of the Truesdale Medical Center team.
