Patient Reviews

I felt very comfortable in discussing issues with my knees. Dr. Lohrbach showed compassion in discussing surgery and discussing X-rays. The exam of my knees was great. I look forward to having him do my surgery.

Dr. Lohrbach and his team are excellent in listening to health needs. Great care and compassion and addresses options of care! I left with all my questions answered.
Dr. Lohrbach has been amazing to work with! There’s never any pressure to have something done you don’t need. Can’t say enough about him and all the people that work at OSI.
