I've seen Dr Grus for over 20 years. That alone should demonstrate to you what I think of him as a doctor and as a person. He's my wife's primary care physician also and we both have always been completely satisfied with his care. The facilities are well laid out and clean to receive in-office testing. Overall we are very pleased with Dr Grus and the group at Progress West.
