Agree with a previous reviewer. Have been trying to get the doctor on the phone for the past 2 days. Left a VM, waiting on hold for 30 mins, currently on hold. Absolutely unacceptable.

August 20, 2024Tashi Y.Verified patient
I like his bed side manner and he’s a preventive doctor. He wants to make sure nothing goes wrong later and to mitigate any risk. Makes sure you are part of the process in deciding which treatment you would like to go with.
August 13, 2024Sheikh A.Verified patient
Genuinely felt like Bassil listened to me and was very much interested in my well being. I never felt like I was interrupted, he wanted to hear everything I had to say, and he talked me through his plan of action for me. I feel really safe in his care and I look forward to working with him to get my blood pressure under control. Thank you for making me feel comfortable.
July 3, 2024James V.Verified patient
Dr. Bassil has a great bedside manner and provided good insight and advice for the management of my conditions. He is very non-alarmist and practical, which I very much appreciated. I also use this Summit Health office for my primary care and dermatology needs and I am continuously impressed by how well the office is run from the promptness of appointment times to communication before and after my appointment.

The office and staff are great, especially the nurses. But the doctor was the problem. He didn't asked me any questions, just heard me without really looking at me, and ordered some extra tests and told me the way out. Not even stayed to ask if I had any further questions or try to explain what I could be experiencing. It fell like one of those doctors that treat machines, not humans. Went to another provider in another location and they were much more thorough. I wouldnt recommend this doctor.
