Everything and everyone is great here. Dr. Thanjan is polite, personable, and always so professional. I have complete confidence in him.
Nice thorough and cordial interaction with Dr Thanjan (though the office was running about 30 minutes late by the time I saw the doctor... typical these days). Easy check in process. The patient portal website interface used by this group is a bit amateurish by today's standards.
Dr Thanjan is exactly what you would want in a doctor--kind, through and knowledgeable. He had carefully read my records transferred from out of state, and, because of two important facts surrounding my previous colon cancer, he made what I felt to be the best plan for my care going forward. I have had new doctors who hadn't even looked at my records before meeting me. It was comforting to know how careful he will be with my health. And his staff was awesome--actually answered their phones and we're courteous as they gathered my information. So happy with this practice!

He is the best! Kind, professional and a good listener. Always takes a lot of time and you never feel rushed out. I highly recommend him.
I was seen within minutes of my appointment time. Everyone was helpful and pleasant. Dr. Thanjan fully and clearly informed me about his observation and recommended procedures. I never felt rushed but was leaving his office 30 minutes later.
He was kind and listened to everything I had to say.
