East County Family Dentistry in Santee operates from 9280 Mast Boulevard near Mast Park, where lead practitioner Homayoun Ardjmand, DDS earned his doctorate at the University of Iowa in 1991 and holds a magna cum laude undergraduate degree from the University of Denver. The multi-specialty office provides general dentistry, orthodontics, pediatric care, and implant placement under one roof, and its pediatric caseload coordinates with Tonya Henderson, MD at Sharp Rees-Stealy Santee for children requiring medical clearance before sedation procedures. Staff fluency in Farsi, Spanish, Arabic, and English serves Santee's multilingual households, and a voluntary clinical instructor appointment in the Department of Family Medicine and Public Health at UC San Diego Health Sciences connects the practice to academic training pipelines. Additional offices in Chula Vista and Escondido share patient records, and the Mast Boulevard location's sedation-dentistry program for patients with dental phobia coordinates behavioral-health referrals through MHS Action East on Cuyamaca Street. Invisalign, ceramic bracket, and traditional stainless-steel bracket systems deliver orthodontic forces of 25–150 grams per tooth through 0.014- to 0.019 × 0.025-inch nickel-titanium archwires sequenced over 12–24-month treatment plans.
