He's been my Dr for years. Very high level of trust. He communicates in a straightforward manner, with no fluff. Extremely knowledgeable and relates in real world terms.

He has been my primary care physician for 35 years. He is an excellent Doctor, with great respect for his patients. My only regret is he is retiring and I know it will be hard to find another Doctor to fill his shoes for me as a patient. He was superb.

We’ve built a relationship over years of care. He knows me, and knows my preferences for things like prescriptions or specialty care.

I came in with severe abdominal pain. Dr Mackessy said it was a UTI and prescribed a sulfate. Three days later the test results were posted as negative. However the medicine had wiped out my gut flora , leaving me with C-diff, horrible pain, nausea and diarrhea, resulting in a 16 pound weight loss and a traumatic trip to the emergency room.
