10/21/2020 Updated reviewI just got the most laughable , absurd , horrendous bill of $14000.00 from Dr.Grasso. This individual is the most deranged , heartless and pigheaded doc I have even known.Lets explain;However unbelievable and ludicrous it may sound , this is true story. Nothing but the whole truth and proven facts. .I have consulted and treated with Dr. Grasso between 1991 and 1995. I had two insurances at the time. He prescribed 4 part procedure Three parts were descent and adequate till the fourth part . At one point , there was a balance of $120 due. When I went to dr Grasso for the fourth part appointment , he refused to treat unless I paid$120 . I felt awkward and I told him I wont be coming back to treat anymore. First , my two Insurances shouldve cover any periodontal treatment at the time. Second , I felt astonished and in disgust with Dr. Grasso insensitive, cruel, merciless behavior.Third, the last visit was the last part of four visits. His decision to halt his medical responsibility turned out dismal for the undone part.I have informed Dr.Grasso of my intention and asked him to charge my insurance although the job was abandoned by the Doctor. My insurance at the time simply refused to cover Uncompleted service.Mr Grasso had unfairly and illegally reported me to the credit bureaus for 7 years. After, that he succeeded to illegally report me for additional 7 years. Which is against credit reporting guidelines. I asked the attorney General office to intervene but Dr .Grasso refused to respond . I then , filed a complaint with the licensing board , they were grossed out by his irrational behavior.To my big amusement ,Dr. Grasso just sent me a bill of $11340today . More than 100 times the original amount . This dr. Is not to be trusted. He doesnt behave like a doctor. He has a mentality of a mob He doesnt act like a normal person. He makes his own laws . Not only he halted the much needed 4the part procedure (which is unethical and unprecedented), he went out of his way to ruin his patient credit and now he unlawfully charging ludicrous, unimaginable amount. This doctor must be avoided by any means. He lacks professionalism , he lacks compassion , he lack common sense. You need an attorney to treat with him. Abstention is recommended.Stay away from this fake , stubborn , cruel doctor. He is the worse doc I have ever met.
