An Important Message from Dr. Mayer

Dear Friends, Patients, Colleagues, and Staff,

As I close this chapter after 42 years in family medicine, I want to express my deepest gratitude. It has been the honor of a lifetime to care for generations of patients, to celebrate milestones, and to walk alongside families through both joyous and difficult times. Thank you for trusting me with your health and your stories—your confidence has been the foundation of my career.

To my colleagues, I am grateful for your support, collaboration, and friendship. Working beside you has made the journey both meaningful and fulfilling. The exchange of knowledge, ideas, and encouragement has enriched me beyond measure.

To my staff, past and present, thank you for your dedication, compassion, and professionalism. Your tireless efforts made it possible to deliver the kind of care I always aspired to provide. You have been the heart of the practice, and I could not have done this without you.

Family medicine is about people and relationships, and I have been blessed with the very best of both. As I step into retirement, I carry with me a lifetime of memories and the privilege of having served a community I deeply cherish.

With heartfelt appreciation,

“Dr Marc” Mayer
