Nice to Meet You

"I feel the physician-patient relationship is the cornerstone to excellent patient care. Communication between a patient and their physician should feel natural and open. In turn, this open communication fosters a powerful and lasting relationship."

Dr. Handler brings dual board certification in Otolaryngology and Cosmetic Surgery to ADVENT. He received his MD from the Medical College of Wisconsin before returning to his native state of California, where Dr. Handler completed his residency in Head and Neck Surgery with Kaiser Permanente in Oakland, California. During his residency, Dr. Handler embarked on numerous surgical medical missions, operating in a variety of third-world countries, providing care for those in desperate need.

How I Can Help

5 star rating iconExpand Content Icon
"I went to ENT's for years and they did very little to help my sinus issues. They just prescribed nasal sprays for years, one after another. Advent was great. All appointments were very detailed and informative. They spend a lot of time looking into my sinus problems. My breathing is so much better but not perfect after my procedure. I will take the improvement they gave me any day over the ENT doctors I saw before."

This place has literally changed my life. I have been a lifelong sufferer of sinus problems. Through the years, I have tried multiple over the counter remedies, seen several ENT specialists, and had a majorly invasive sinus surgery. None of it has ever really helped, and the surgery made it worse. I went to ADVENT...and I'm breathing more clearly than I ever thought possible. They truly delivered significant results. I am and will forever be grateful for the major improvement in the quality of my life.

This is a 1-stop-shop for issues dealing with those miserable nose, sinus and throat and breathing issues with lots of solutions and info to make an informed choice. Don’t waste your money on "a" specialist when it's all here under one roof and very reasonable cost wise. All we know is to go to Sleep centers that will slap miserable CPAP machines on you which only help with sleep disorders. Allergists give you sprays. Helpful....but ADVENT addresses several areas of sinus-nose-throat concerns. My Family member was given a Balloon Sinoplasty because sinuses were in bad shape from all previous nonsense and chronic drowning in mucus. He back at work next day with mild discomfort for 2 days. Major improvements! Was told if this didnt help as much as hoped, other things could be assessed. Very nice staff. Terrific follow up aftercare and support all along the way. very professional.
