    “Growing up in a small town next to Zion’s National Park in southern Utah, I cultivated a love for outdoors and hiking at an early age. I am grateful to now look out my window every day and see the beautiful Organ Mountains so close by. New Mexico is a unique and diverse place and my family feels at home here.”

    Dr. Elliss is currently involved in local cub scouts and enjoys being a supporter of NMSU athletics and student organizations.

  • Dr.
    Cory Thompson, DMD

    Dr. Cory Thompson attended Arizona State University where he graduated Summa Cum Laude with a bachelor’s degree in Spanish. Dr. Thompson then went on to graduate from the University of Pittsburgh School of Dental Medicine out east where he loved the seasons but learned to appreciate the fact that you never have to shovel sunshine. At his family’s request/urging, Dr. Thompson set out to practice in the desert southwest. After some time spent in Arizona, New Mexico became home and he and his family have grown to love the area and the people.

    “There is a uniqueness about Southern New Mexico that I really enjoy. I love the spectacular mountain views and White Sands National Park. This is a place that my family and I are excited to call home. I am looking forward to helping the people of Deming with their dental needs and I am excited about the many wonderful options that we can provide for you at Rio Mimbres Family Dental & Oral Surgery.”

  • Dr.
    Robert Espinoza, DDS

    Born and raised in New Mexico, at a young age Dr. Espinoza knew he wanted to be a dentist. The path was not always straight and clear but with encouragement from his family, friends and church he had faith he would achieve his goal. He started to develop a hard work ethic while attending Las Cruces High School and working at Memorial Medical Center as a Sanitation Aid. 

    After graduating from high school and completing a certificate as a Certified Nursing Assistance, he worked at Las Cruces Nursing Center and attended NMSU School of Business and College of Arts and Sciences to complete pre-dental requirements. Upon completing his Bachelors in Business Administration and all pre-dental requirements, he was accepted into Loma Linda University School of Dentistry. There he served as class president all four years and was a part of the Dean's List for academic achievements. In his senior year he was nominated and won several leadership awards including recognition by the California Dental Association for research and the Prince Award. 

    Dr. Espinoza was accepted into the University of New Mexico Advanced General Dentistry program. He studied an extra year of day-to-day dental procedures in a clinic and hospital setting, as well as LV. sedation, dental implants, endodontic, fixed and removal prosthodontics, advanced pediatric cases, periodontal surgeries, impacted wisdom teeth removal, emergency dentistry and preventative dentistry. It was an intense year but working with specialists in each of those areas has helped mold him into a better dentist that wants to continue to grow and learn. 

    After having several job offers around the U.S., Dr. Espinoza decided to take the job at Sonoma Family Dental and proudly serve his community that helped him in achieving his own goal.
