"Awful physician. He only cares about $$$. ... This office sucks. My husband was given an URGENT referral for a foot infection. After three weeks of “trying” to get an appointment ... my husband had to be admitted to the hospital with talk of losing his foot."
— Healthgrades/Birdeye reviews"Dr. Mani is one of the kindest, most caring and compassionate gentlemen one can ever meet. He is also one of the most intelligent humans on earth. ... I know him both as a patient and a referring MD. 5 STARS!!!!"
— Birdeye reviews"Mani is one of the dumbest cardiologist that we have seen to date, not only he can’t recognize the signs and symptoms of a patient, but has the balls to tell the patient that everything is fine and see him in 6 months."
