Your Board-Certified Livermore, Pleasanton, & Tracy Orthodontist
Meet Dr. Tom Marcel
When Dr. Tom Marcel opened his first orthodontic practice in Livermore shortly after graduating from the University of California, San Francisco in 1991, he set out to create more than a place where patients could straighten their teeth. He wanted to build an office where people felt welcome, cared for, and excited to come back.
Since then, he has dedicated his career to serving local families while remaining actively involved in numerous dental boards, clubs, and professional associations.
More than 30 years later, he still loves coming to work each day and helping patients discover what a healthy, confident smile can do for them.
