Meet Our Doctors

Originally from Kansas City, Missouri, Dr. Tom Marcel did most of his growing up in San Jose. He attended Santa Clara University, where he graduated with a Bachelor of Science degree in Combined Sciences (biology, chemistry and physics). He went on to the University of California, San Francisco, where he received his dental degree and orthodontic specialty training.

Dr. Marcel has published articles relating to temporomandibular joint (TMJ) function and mandibular movement in professional journals and lectures to orthodontic and dental organizations throughout the U.S. and abroad. He also maintains teaching affiliation with the University of California San Francisco, University of the Pacific and the University of North Carolina.

He is co-founder and co-coordinator of the Livermore Community Dental Care, a non-profit organizations providing dental care and education to Livermore school children.

Dr. Marcel and his wife, Claire, also an orthodontist, enjoy living in the Livermore community with their two children. They have been involved in various civic programs such as coaching, sponsoring youth teams, Boys and Girls Club, scouts, local theaters and 4H clubs. His hobbies include reading, movies and cooking. As a sports nut, Dr. Marcel spends his time away from the office playing softball, running, bicycling and playing golf. Also a hockey enthusiast, Dr. Marcel is a big Sharks fan!

Dr. Claire Ogata Marcel was born and raised in Sacramento, CA. She achieved her Bachelor’s Degree in Biology and her Master’s Degree in Human Physiology from the California State University, Sacramento (CSUS). Her medical illustrations were featured in many research publications and she provided the art for the physiology workbook used at CSUS. During her Master’s Degree Program, Dr. Claire immersed herself in research cardiology at the University of California, Davis Medical Center (UCDMC). This research included clinical studies for new anticoagulant drug therapies and development of laser angioplasty.

Dr. Claire received her Doctor of Dental Surgery degree in 1989 and her Orthodontic Certificate in 1991 from the University of California, San Francisco (UCSF). Her research at UCSF was in three different areas; AIDS, congenital craniofacial malformations, and bone cells (specifically osteoclasts and osteoblasts).

After a volunteer mission to Nepal with a Cleft Lip and Palate Team, and during an Assistant Professorship with the UCSF Division of Orthodontics, Dr. Claire opened an orthodontic specialty practice in Tracy. Her first Tracy office was built and opened late in 1992. It was located on Tracy Blvd. across from the Sutter Tracy Hospital. Later she moved her office to the three story glass building farther north on Tracy Blvd.

Since then and because of demand and Dr. Claire’s passion for Orthodontics, she has been able to treat a small group of patients in the Livermore office once or twice a month. Time swiftly passes amid lacrosse, soccer, scouts, and piano. Dr. Claire’s art career continues to develop. Lampworking glass, metal, wires, and found objects are currently her mediums-of-choice. There are also a few unfinished oil and acrylic paintings lingering in her small studio. Exercise has slowed to a game of golf or a walk with the dogs. If there are any extra bits of time, she pulls out her Kindle or a crossword puzzle.
