    Dr. Joshi diagnosed me with a problem my primary care missed. It turned out to be very serious. I had to wind up getting a pacemaker put in. He has an excellent bedside manner.

    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.
