Biography

I am a board-certified otolaryngologist - which is a head and neck surgeon. A Phi Beta Kappa graduate from UCLA with highest honors, I graduated with distinction from the UCSD School of Medicine in 1996. I had my "calling" at age five when my newborn sister was born with a congenital condition. I was so impressed with the care she received from her physicians, that I made a vow to become a doctor so I could help other people in the way the doctors helped my sister.

I have authored several publications and have given many presentations in the field of otolaryngology. I have a special interest and expertise in thyroid and parathyroid surgery, endoscopic sinus surgery and nasal surgery, otologic microsurgery and facial plastic and reconstructive surgery.

In my spare time, I race cars, travel extensively, attend musicals, concerts and cultural events and try to enjoy San Diego for all it has to offer.
