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.
