Lico Castillo, DDS, MD

Meet Dr. Castillo, our skilled oral surgeon since 2022. As a board-certified oral and maxillofacial surgeon, Dr. Castillo brings expertise and precision to every procedure. Trust in Dr. Castillo’s experience and commitment to exceptional care for your oral health needs. Dr. Castillo was born and raised in Snyder, a small town in west Texas. Growing up, he loved and played football. He earned an athletic scholarship to play football at New Mexico State University. During that time, he realized God had a different plan for him, and he devoted himself to studying.

As a dental student, Dr. Castillo was fascinated with Oral and Maxillofacial surgery after shadowing a very complex facial reconstruction procedure. A dual degree program was offered to Dr. Castillo through the University of Missouri-Kansas City as one of two residents selected.

He graduated from medical school and completed an Oral and Maxillofacial Surgery residency program in 2021. During his time there he married his beautiful wife Jordan who also shares his love for dentistry as a Pediatric Dentist.

Although Dr. Castillo is highly educated and surgically gifted, what sets him apart is his ability to treat others with care and kindness. Having the opportunity to help people every day is what he appreciates most about his career.
