Your trust is our top concern.

We strive to keep reviews honest, trustworthy, and fair.

Doctors can not pay for good reviews, nor can they pay to have negative reviews removed.

We monitor all reviews to ensure they comply with our guidelines and don’t include personal information, profanity, libel, defamation, harassment, obscenity or fraud.

Any reviews that are deemed fraudulent or violate our guidelines will be removed immediately.

All reviews are confirmed and audited before publication, and community members have the ability to flag inappropriate content for further review by our team.

Dr Blau has been my Dr for over 20 years. His care has been exceptional. Always responsive and has taken time to coordinate my treatment with my other doctors during my recent health crisis. He takes the time to review other testing I need done and follows up with me. His staff is wonderful too. Thank you Dr Blau.

Dr. Blau has horrible bedside manners. In-person he is rude and condescending. My mom was a patient of his. Due to her limited English I went to translate. He was upset, rude and short tempered when asked a question. He did not give me time to translate his response. It was as if how dare I question him. He opened the door was responded in the doorway. I highly suggest another doctor if you want to be treated like a human being. I’m appalled with his behavior and professionalism.

I didn’t wait at all, they took me in right away each time. Dr. Blau was very thorough and called me himself with my test results. Everyone was professional and courteous

I came to use Dr. Blau recently as he is an Internist/Cardiologist. He was all business and had no desire to have any kind of a connection with me as a patient. I visited him today (8/18/2020) for an echocardiogram. While is was there I told him that i felt my sinuses may be inflamed as this is a chronic problem i have. Dr. Blau has listed himself an internist as well as a cardilogist, yet he refused to look up my nasal cavity, telling me that I should go to an ENT. If he says he is an internist, then he should act like one, and not just try to get rid of me. There were several other questions i asked him, and he was totally annoyed and actually sarcastic.

I started seeing Dr. Blau after I had my son in 2016 I had preeclampsia and post partum hypertension. Nobody could get my pressure under control. He was recommended by a friend of a friend and ever since then he’s been my doctor. He got my pressure under control. He is an Excellent doctor. He is always there to answer any questions no matter when you contact him . I’m sure I drive him nuts but he always responds quickly. Been having a tough time lately and he was the one who found what was ailing me after 3 ER visits which were inconclusive. He doesn’t mess around , he is no nonsense but he will crack a smile once in a while :)

I truly wish I could Give no stars . Dr. Blau was the “on call doctor “ the night my grandfather (94 years old) passed away . Unfortunately, it was the middle of the night when this had happened (obviously out of anyone’s control) and protocol has it that since he passed away in his home , the police and EMT are the first to respond to declare him deceased . Part of this process, the police had to speak with my grandfather’s doctor or the “doctor on call” from this practice to confirm that my grandfather was under the care of this practice .When Dr. Blau was contacted he Had told the police , this is a matter that could wait until the morning and hung up. Not only were we, the grieving family, shocked at this response , The police and the medical examiner were also dumbfounded. You see , if you are ever in this situation where you chose to keep a loved one at home to pass peacefully , the body can not be moved from the house until this gets cleared .

Dr. Blau is exceptional, but his office personnel are far from professional. The answer questions they don't know the answers to which ends up costing you out-of-pocket. Their response when you question is "That's not something we would know the answer to, call your insurance company" after assuring you not to worry when they answered in the first place. He is too good of a doctor to have that kind of staff working for him. (he is 5 stars, office is 0)

Dr. Blau is exceptionally smart and caring. In addition to spending time with the patient, he also spends time with the patient's family. Without a doubt, he is a wonderful doctor. He has been my father's doctor for 14 years. There is no doubt in my mind that the reason my father is alive today is because of the excellent care given to him by Dr. Blau.
