Always "in and out" so quickly. I feel rushed, like I'm just another of many who are on the doctor's conveyor belt for that day.

Although she seems to be a good doctor, she did not say anything about the fact that after 2/21/2024 she would no longer be a participating provider in my insurance plan. My insurance has said I need to find a new cardiologist if I want to be covered by my insutance.

the doctor was very good at asking and listening to questions and answers. I did not feel the need for more tests ,but she explained her reasons and I am satisfied. I also did not feel rushed in our conversation.

5 out of 5 stars

Dr John kindly got me in on very short notice for a surgical consult/clearance just 4 days prior to my booked surgery. I absolutely loved her immediately! She was kind , caring and understanding of my predicament. She asked me all pertinent questions as to my health and my current cardiac issue at hand. Went over my recent and passed bloodwork and test results and did a ECG in the office “ which ultimately cleared me for surgery”She took her time…I never felt rushed,. She compassionately and professionally answered all my questions without me feeling like it was a “silly” question. Thank you Dr John and your supportive office team (whom were also top notch!!) Thanks to you I have anew hip and am on the mend. I can’t wait to finish my recovery to try out my new hip joint ( I can’t wait, so excited!) Sincerely and Regards, Thank you again! Carolyn

After seeing Dr John for 1 visit only (so far), I am very impressed. She ordered some tests that were very critical for diagnosing my hypertension. I am seeing here again to go over the results and looking forward to having her as my cardiologist
