Mitchell Kleinberg, MD

Very professional doctor, respectful and courteous. He is very knowledgeable in his field. Both of my children has seen him from baby through teens. I highly recommend Dr. Kleinberg.

Dr Kleinberg misdiagnosed my daughter when she was having an adverse affect to a medication which was stated in the white pamphlet.. she had a tremendous increase in urination. He diagnosed her with a yeast infect which he said also has an increase in urination ( being a woman we know that is absolutely not true) she was in a baby pool that day. He urged her to stay on meds a few days later welts appeared and she couldn’t walk without pain, joint pain all over... screamed when car stopped, when she got to the hospital they determined she was having an adverse affect to medication Eurothema minor and needed to be hospitalized... always trust a mother’s instinct...

Basically called my 4 year old child fat to her face.

We’ve seen him for both our kids. Very caring and professional.

Great doctor

Dr. Kleinberg is amazing. His information is helpful and accurate. He is sweet and intelligent and has a good bedside manner and spends so much time answering questions and discussing everything with you. He explains everything and gives good advice. However, his office staff is miserable and the nurses and office staff make so many mistakes - like my child's immunization charts. Immunization charts should not have mistakes. I have never experienced wait times as long as theirs-- sometimes it was 2 hours long for a scheduled appointment. This should never happen. We left, because we could not deal with this place. Too much aggravation and stress. However, I still miss Dr. Kleinberg. He was the best!!!

Dr. Kleinberg is the best doctor! I trust and respect all the advice he gives me for my children.

I try to see Dr. Kleinberg, but all the doctors at the practice are excellent. He is one of the best doctors we see, he treats your child like they are one of his own kids.

As large practices go this one is GREAT!The availability is great the Holbrook office is open 7 days a week including holidays...the doctors are knowledgeable and nice.
