4 and 1/2 years ago I had a quintuple bypass. Dr. Allo allowed me to call anytime when I was scared to death during my recovery and always determined if I needed another hospital trip or not. I can't tell you how much easier that made the recovery process knowing he was a phone call away and I still thank him for it.

DO NOT SEE THIS DOCTOR. I've seen this doctor twice. I took the medicine he prescribed for hypertension and ended up in the ER with a systolic pressure of 217. Still believing he knew best, I continued to take the med and every evening experienced a BP of 190+ for four evenings. I contacted his nurse who said she would call back with instructions from the doctor. She did not do so. There is no possible excuse for this kind of irresponsibility in his position of trust.
I apologize for the experience you received. I take every comment seriously and have reviewed your situation with my staff. We never want anyone to walk away with a bad experience. I hope you can accept my apologies and we will strive for the best patient care.

He is very professional, caring. When my husband developed problem with heart, got immediate appointment, immediate action taken to cure the problem.
Dear Pat, Thank you so much for your comment and you confidence in my care. I hope that everyone receives the same care that your husband did. We look forward to seeing you and your husband in the near future.
