M.G. July, 13, 2017

"I want to thank you for seeing me last week and for your overall demeanor and presence.  I really appreciated your empathetic ear and expertise.  You have a unique gift in relating to your patients.  Being a healthcare worker myself, I appreciate hearing positive thoughts from my own patients so I felt it important to share this with you.  You have a unique gift most MDs don't have so thank you for sharing it with your patients."

H.H. February 13 ,2017

Betsy G. June 26, 2015

"After my facial trauma in 2011, I had severe sinus issues from infections to difficulty breathing.  Dr. Rao assessed my symptoms and made surgical recommendations that were conservative yet direct for solving my problems.  One surgery (4 procedures in one) and two months later I am breathing freely again.  No more sinus infections.  No more discomfort while flying.  I am truly a new man.  Thank you so much Dr. Rao."

Tom A.  March 18, 2014

Andrew O.  March 5, 2014

"Professional staff.  Excellent listening skills and effective treatment to resolve my problem."

Michael P.  March 5, 2014

"I had a tympanoplasty performed by Dr. Rao about seven years ago and sinus surgery three months ago.  I believe Dr. Rao recommends surgery only when necessary and all conservative measures had been attempted first.  Dr. Rao is a highly skilled surgeon.  I had minimal pain and both surgeries have been very successful.  Having grown up with numerous visits to the ENT, I developed a fear of the "ENT chair", but Dr. Rao and his nurse have an excellent "bedside" approach and I always feel comfortable in his office."
