Andrew Grainger, M.D.
He is the best! Such a great “bedside manner”, makes you feel like you are his only patient. He listens to you & is fully aware of your file/history! Does not rush the appointment time. God bless him, he is very special!
Andrew Grainger, M.D.
In my initial meeting with him, he had already looked at my chart. He knew I had pulmonary embolism several years ago. So he recommended a different drug because of this. He made me feel cared for.
Michael Ozga, M.D.
I very much appreciated Dr. Ozga and his kind, truthful approach. My daughter and granddaughter are both nurses and accompanied me to the visit. They were both favorably impressed as well.
Anish Parikh, M.D.
