GUILLAUME BASSIL, M.D.

Google review (Rita Casas): Dr. Bassil and his staff are excellent. Got an appointment as first time patient in 2 days. And 2 weeks after I had a whole series of tests plus the results. This is what medical care should be. Very happy here.

Google review (James Vardakis): Never had a bad experience with Dr. Bassil. Great 'bedside' manner - takes the time to listen to you and come to the right course of action. I came to the office at a very vulnerable time with scary high blood pressure and he's gotten it under control. I feel like I'm in good hands with him as my cardiologist.

Google review (adam lawrence): I’ve had nothing but great experiences with Summit and Dr. Bassil. The staff is great and his bedside manner is perfect. He got me into all the right tests quickly, and the clinic had most everything I needed right there. The entire experience was efficient, and pleasant. I can’t recommend them more highly.

Google review (Zaffar Hayat): One of the worst experiences of my life. I did the mistake of going to this Summit Health facility in early November 2023. I made sure and asked if Dr. G. Bassil was in network. His office confirmed that he was in-network. I have health insurance. Now I am receiving bills for $1k. I have called his office, the office manager in never available and I was told recently by the staff at the office that it is not their problem, contact Summit billing. I contacted Summit billing department multiple times, and they cannot help or bill my insurance properly. I have emailed summit health directly, no response either. On top of it I now have to find another cardiologist because this doctors office cannot resolve the billing issue. I would not recommend this office to anyone.

Google review (Vishwa Vasani): Had a very frustrating experience with Dr. Bassil’s office. Had a test scheduled weeks in advance, only to come here and find that their system was down and the tests would have to be rescheduled. They should at least have let us know over phone call beforehand, it is not easy taking time off of work. It seems like they have no respect for their patients’ time and energy.
