Mario Samaniego, DDS

Dr. Mario Samaniego is originally from El Paso, Texas, but at a young age migrated to California, where he attended high school and dental school at Loma Linda University. After dental school, he joined the USAF for specialized training in every area of dentistry.

In 1984, Dr. Samaniego started his practices in Las Cruces and Alamogordo, New Mexico. Growth in both practices occurred so quickly that he had to bring in other doctors to assist with the patient load. Continuing education has been one of his top priorities, and being in general dentistry requires keeping up with the latest developments. Dr. Samaniego has been able to help many patients with TMJ problems, orthodontics, complete reconstructions and cosmetic dentistry. Dr. Samaniego is one of 240 dentists in the world that practices the Bio Esthetic Dentistry Technique when treating his patients. This technique combines stable TMJs in the alignment with the patient’s bite to create long-lasting, beautiful smiles. In 2008, Dr. Mario Samaniego was selected by Consumers Research Council of America as one of America’s top dentists. He is among a select few that have earned this prestigious recognition. He has also been named as the Favorite Dentist in Las Cruces by Las Cruces Sun News readers.

Dr. Samaniego is very concerned about education for our youth and for years has been involved in raising funds for scholarships. Several years ago, he founded a program that provides scholarships for senior students going to college. So far, about 100 scholarships have been given to students.

His hobbies include dentistry, cycling, old cars, gardening and traveling.
