John Nathan Allan, M.D.

I feel blessed to have been referred to Dr. Allan. He is not only professional and extremely knowledgeable, but more than willing to spend as much time as necessary to explain complex medical issues and likely outcomes in comfortable layman terms. He and his staff truly care about the individual patient - his obvious kindness and patience put me at ease immediately.

Dr. John Allan is an amazing physician. Very skilled, patient, and knowledgeable. He diagnosed my condition correctly and prescribed a medication routine that works very well. I cannot be more grateful and pleased and would refer him to anyone. He is a true professional.

Dr. Allan is a great doctor. He takes his time and explains everything in a way that is completely understandable.

Dr. John Allan is a very fine intelligent doctor without him, his team and Presbyterian hospital I don’t know how life would be right now.

Brilliant Doctor! He is on the case very detailed and clear with the objective. I would recommend him. Very intelligent doctor. He really knows his business. Thank-you!!! I feel fortunate
