What Our Patients Say

"Dr. Rao is excellent. She is very kind and compassionate. She is a role model for how all doctors should practice. She was very thorough in explaining my issue to me and the procedure she would be doing for treatment. I appreciate her seeing me for an unscheduled emergency procedure on a Saturday. I am very confident in her knowledge and ability to treat my torn retina to prevent further damage to my sight. She called me the next day to check on me. I 100% recommend Dr. Rao.""

Yes the wait can be a little long but for wonderful eye care, I'll watch the television to stay occupied. Such a sweet lady with gorgeous hair at the front desk..she can handle 5 things at once and keep a smile on her face . Love my Lombard office,but will go to oak Park if I have to as long as I see my doctor and at least a few of my nurses that I've dealt with over my time . Keep up the great work!!""
