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.

Should not be working there.
My husband had a forehead wound that needed stitches. We waited 5 hours and never saw a Dr until I complained, at that point this Dr came in with glue and began to glue the wound before anyone had cleaned it. I had to intervene. He wiped the glue off and left. Later after wound was clean he came back in and continued to glue even though I wanted it stitched. Today, one week later, there is a gaping hole in my husbands forehead and he is spending his day off at urgent care to have the wound fixed properly. And will need antibiotics. This Dr. has no business practicing.

Worst ER doctor- would give no stars if I could!
Took my 4yr old in to get a head out of his nose and dr Grossman was the rudest doctor and told us he couldn’t do anything we would have to continue to blow in my sons mouth to try to get the bead out! Took my son to another ER and within 5 mins of being seen they got the bead out! If you have Dr. Grossman leave immediately he won’t do anything to help and he won’t even care!

If You Get Him in the ER, LEAVE!
Went to the ER with excruciating pain in lower back and abdomen, as well as a raging ear ache. He didn't even look at my ear. Had maybe three minutes of his time. Got an MRI, no kidney stones, but still had the pain (which continues to this day to a lesser degree). Said he'd return. Never did. Was sent home with to Rx's by a tech. Worst ER doctor ever! Portsmouth Regional should fire him for incompetence and lack of bedside manner, as he seemed to be annoyed to see me. As well, he was screaming at someone down the hall to not go against what he wanted done. I think it was a patient who clearly had mental health issues, but not sure. Either way, he was screaming at someone in the hallway of the ER. Very unprofessional.

My husband saw Dr Grossman for approx 2 mins Dr Grossman did absolutely nothing he looked in one ear barely an wrote him 2 prescription for pain an inflammation. When we went there to get answers after hearing so many good things about your hospital. That's why we came from citrus county to your hospital. The wait time was quick , not as quick as the doctor. Before they had to check him out they came in to take his vitals blood pressure 198 /110 . Nurse was concerned dr was not. Wont be back
