"Dr. Wu and his staff are personable, caring and knowledgeable!"



"Dr. Wu provided quick, clear and concise information. He ensured that all my questions were answered with detailed insight that put me at ease with the upcoming process."



"Managed to squeeze me in super last minute due to some hearing loss and pain I started experiencing. I saw Dr. Wu and he put me at ease and was generally just a really cool dude with great bedside manners. He cleaned my ears out in about a minute, and my pain was gone instantly. I don’t think I’ve ever heard this well in my entire life. Will definitely be coming back for any ENT issue. This is how healthcare should be!"
