The absolute worst doctor you could ever go to. This man does not care about his patients. He is my grandmothers doctor he does not 1 test for her. She has many health ailments, because she is elderly, and he doesn’t even send her for blood work. She has also have many hernias that were found by other doctors because getting an image of the area is a procedure that he “wouldn’t give his own mother”. Yes, he really said that to us. There are other very good doctors in the area. Avoid him at all cost if you value your life.

Dr. Longo is friendly,attentive and very knowledgeable. Always in a good mood and very personable. The people in his office are just as nice as he is.

Dr. Longo has been my elderly mother`s doctor for many years; too long in my opinion. Mom has not had an EKG for more than 15 years and when she requested one, Dr. Longo promised her he`d do one next visit. On the next visit, he put her off AGAIN! We will see what happens next month. Mom has had a serious skin problem on her face for a few years. Now, of course it`s cancer. Is Dr Longo BLIND?? She has just has Mohs surgery for this condition but this wouldn`t have been necessary if Dr.Longo had strongly encouraged my mom to see another dermatologist when she reported that she didn`t like the one Dr. Longo recommended. I would never send anyone to this Dr.

This is the best Doctor in Waterbury. I only hope, with this review, he doesn't get too many patients! :-)

Dr. Longo is average at best. He is an old fashioned neighborhood doctor who can be very abrupt and condescending. He does not follow through with other ailments you might have. Advises you to seek another Doctor but makes no recommendations as to how or where to find the best care for your problem. He takes the path of least resistance. Gives the impression he can't be bothered and only wants to handle "basic care" needs. Definitely a "take two aspirin and call me in the morning" kind of Doctor. His office staff is unprofessional and has an attitude problem. There are plenty of more qualified and caring physicians in the area. I would not recommend this office.

A Doctor who care`s about his patiant`s-see`s to the out come of the condition.FRIENDLY, ASK`S QUESTION`S THAT LET`S YOU KNOW HE REMEMBER`S your concern`s. I would recomend him to other`s.
