Michael Minckler, MD, MBA

From an early age, Greg knew he was called to serve others through medicine. Fluent in English, Spanish, and French, Greg is an adaptable and experienced medical professional with a strong background in assisted living, palliative care, emergency response, and preventive medicine. His extensive experience includes serving as the Deputy Chief Medical Officer for Operation Afghan Welcome, where he led a team of 200 healthcare providers caring for approximately 10,000 Afghan refugees. 


Today, Greg serves patients at Freedom Primary Care, where he is recognized for his ability to offer a broad range of medical services thanks to his comprehensive training. Outside of work, Greg enjoys watching basketball, especially cheering on his favorite team, the San Antonio Spurs. He met his wife Cristina during medical school, and together they share a deep commitment to practicing medicine with compassion and integrity. They have three young children, and when not in the office, Greg cherishes time spent with his family exploring all that the Phoenix area has to offer.
