One Medical Newbie
"Dr Donlan was with One Medical for a couple years before opening his own practice. As his patient for a few years, he never seemed genuinely or authentically interested in my health. His personality did not make me very excited when I had to see him, as he just always seemed condescending and uninterested in having a fruitful conversation about any given topic. If you do not have anything wrong with your health, then he may be just the right doctor for you, but if your condition is one that is complex or serious, I just don’t feel like he is experienced enough to be a doctor for this type of person just yet."
Did Not Do His Due Diligence
"This doctor is fine to go to if you have minor issues or are perfectly healthy. If you require a specialist or have an issue that is complex, he will not don his homework to find out more information. When he left One Medical recently, he wrote comments in my chart that were untrue and caused a great deal of headaches in his aftermath. He is not to be trusted or recommended."
Exceptionally good care!
"He creates a great environment to address all health issues and is thoughtful and intelligent. Not just coughs and sniffles, but rather he addresses the overall health of the body. Exceptionally good care! best I've ever witnessed."
