    I first met Dr. Joshi 11 years ago when my 39 year old daughter had a massive heart attack. He was the doctor on call and had he not been prompt in getting to the hospital and performing her surgery, she would have died. He has taken excellent care of her and she is doing well. He has been my doctor, too. I cannot say how much we admire him and his skills, kindness and attentive nature. He feels like a friend. We have always been treated nicely and efficiently by his staff as well. I give him the highest grade on every level.

    I couldn’t ask for a cardiologist that is as professional and helpful as Dr. Yousuf. I had blockages in both legs, very little blood flow, and he was able to get them opened up and I can walk with no tiredness or weakness in legs! I recommend to everyone who wants a GREAT! Cardiologist!!

    Dr. Yousuf is wonderful – Fantastic Cardiologist. Referred other family members and friends to him. He has done a stent in my heart with great results. On a scale of 1-10, 10 being the best, Dr. Yousuf is a 12+. Wonderful personality – Great bedside manner. Cute!! Sorry married.
