Your trust is our top concern.

We strive to keep the reviews trustworthy, honest & fair.

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

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

Worst PCP
He’s everything that’s wrong with the healthcare system. Mental health concerns were brought to his attention and flat out ignored. Please do yourself a favor and don’t see this doctor.

Dr. Grus was my dr almost 20 yrs. I thought he was a great dr until about 2 yrs ago. I was 67-68. I am diabetic & you need your medication. I had called 3-4 days as I was out of Lantus. The final word, I had to come in to see the dr or he would not refill. I had not worked a lot, hrs were cut. I had $45 for my medicine. If I went in, would have used it for the office call. Working a Sat in Oct. Got dizzy, nauseous, weak, had to go home. I stopped at walmart, got Novolin & needles for $38. Took an injection in my car & waited 20 mins before going home. I felt better & could feel blood sugar going down. It took about another 15-20 mins to get home. The meter couldn't read my blood sugar because it was still over 600. The meter would not read over that #. I could have had a stroke/heart attack. I am in the process of making a formal medical complaint to the State, as I was advised to do this. The Hippocratic Oath says, "First do NO harm."|

Dr Grus is my Primary Care Physician. He is patient, kind and a great listener. I feel he takes my concerns very seriously. The others who work in his office could not be nicer or more helpful.

Takes the time to listen and talk with you find out whats happening. Proactive in treatments. Concerned about patients. He spends time with you and doesn't rush to the next patient.
