Dr. Sara Adabi
Dr. Sara Adabi believes orthodontics does more than transform smiles—it changes lives. She is passionate about delivering personalized, patient-centered care and loves helping patients build confidence through beautiful, healthy smiles. Her work in both local community outreach and international humanitarian programs has been especially meaningful, shaping her compassionate approach to dentistry.
Dr. Sara is a board-certified orthodontist and an Assistant Professor in the Orthodontic Residency Program at Loma Linda University, where she is dedicated to training future orthodontists.
She earned her undergraduate degree from UC Irvine as a recipient of the prestigious Regents Scholarship, received her DDS from UC San Francisco with honors for academic excellence and leadership, completed an orthodontic fellowship at the University of Connecticut Health Center, and returned to UCSF to earn her Master’s in Oral and Craniofacial Sciences and Certificate in Orthodontics.
When she’s not in the office, Dr. Sara enjoys traveling, exploring new foods, hiking, and spending time with her husband and two young children. She is thrilled to serve this wonderful community and looks forward to being part of your smile journey.

Dr. Debra Cook
Being an orthodontist is a fun adventure for Dr. Cook. She loves the challenge of fitting teeth together and truly enjoys getting to know the people behind the smiles. During each appointment, Dr. Cook provides patients with her undivided attention, carefully addressing all questions and ensuring the highest quality of orthodontic care.
Dr. Cook completed her undergraduate studies in Biology at California State University, San Bernardino. She earned her Doctor of Dental Surgery (D.D.S.) degree from Loma Linda University School of Dentistry, graduating at the top of her class. While there, Dr. Cook was honored as a recipient of the California Dental Association Scholarship Award and was selected for membership in Omicron Kappa Upsilon, the national dental honor society.
Dr. Cook then completed a Master of Science degree and specialty training in Orthodontics at Loma Linda University.
