Patient Comments (4)
in Somerset, NJ |
i was left without a quality of life medicine causing me to be unable to walk or be mobile. The office refused to see my wife and sent her a letter they would not see her. The letter did not include me. My script of Enbrel needed refilling. the pharmacy called the doctors office and they refused to fill it. I called the office and they refused to give me a appointment or refill my medicine because of my wife's situation. No office should leave you with out a doctor or the medicine needed.

I have been a patient of his for well over 10 years now. I have referred friends and family to him because I trust him implicitly. I have been to other rheumatologists and they have not compared to his compassion and treatment. He is not in network with my current insurance and I pay out of pocket because of how good I feel he is.
in Somerset, NJ |
Incorrect diagnosis lead to several months of extra pain and suffering that was completely unnecessary. The next doctor I saw got to the correct diagnosis and started an effective treatment plan after only two visits. Dr. Rihacek could not admit he made a mistake and responded to my questions about his with rudeness and unbelievably aggressive and inappropriate (thankfully, as it lead me to find a better doctor).
in Parlin, NJ |
I was a patient for more than 10 years. He's a caring doctor with an excellent staff. If closer to home (and not out of network), I'd still be there.
