I have worked with Dr. Grenis on several occasions, most recently on a repetitive hand injury and deep infection. He's thorough, extremely knowledgeable, discusses treatment options and is decisive when surgery is required.
Case in point, Dr. Grenis admitted me to the hospital late last Friday, preformed surgery Saturday, changed the dressing and discussed pain management on Sunday before discharging me to do my recovery at home. Some doctors would have had me wait until Monday to treat my infection but Dr. Grenis wanted me to have immediate surgery due to my worsening condition.
I highly recommend him without any reservations. I know he wants his patients to have the best quality of care.
