Very knowledgeable; reviewed previous diagnosis from other doctors and determined I need to explore a different path to recovery. Provided next steps to get to the bottom of my multi year issue which has not been resolved by numerous medical providers. Ordered MRI and PT sessions; provided reading materials for strength training, and recommended support cushion to use in the meantime to alleviate symptoms. I’m very hopeful I’ll see results finally under this doctor’s guidance!!
Professional Caring and all around great experience
God bless him, he helped me so much So much with my severe pain even do, I didn't have an appointment the whole stuff treat me really good, that for a moment totally forgot how much pain I had Thank you souch to Othobethesda team and Doctor Marc Gruner
Very knowledgeable and helpful!
Dr Gruner is one of the most sympathetic and caring doctors I have ever visited. He takes his time with patients, goes over options (always from conservative up to drastic) and is not one of those guys who shrugs and says “it’s up to you” when you ask what he would do. He is also very up to date on cutting edge procedures.
Everything about my visit went v well - all the staff were friendly & informative. Dr G, as usual, was calm, clear - and… the shot he put into my hip made the pain disappear!
Excellent patient attention, clear explanation of diagnosis, and detailed description of treatment options. It was a pleasure to be seen by Dr. Gruner, it was one of my best interactions with a medical professional.
Love him!
Professional, and competent care.
Dr Gruner was clear regarding condition ( knee) and recommended treatment. He was exceedingly professional as was his staff.
