Our Office

Rio Mar Dental was established in January 2015 by the husband and wife team of Dr. Arianna G. Martinez and Dr. Jose A. Rios. 

Our office is in a quaint little blue house dating to the 1920s with a rose garden in the front yard. Many patients say that it feels more like a home and not your usual, sterile dental clinic. 

We are located at 201 N. Euclid St. in Fullerton, CA

If you would like to make an appointment or have any questions, please email us at riomardental@outlook.com or call our office at (714) 578-6768.

Arianna Martinez, DDS

Dr. Arianna Martinez

Dr. Arianna G. Martinez and Dr. Jose A. Rios Loaiza practice dentistry together as a husband and wife team. They both graduated from the University of La Salle in Leon, Guanajuato. Certified through the Western Regional Examination Board at the University of Southern California and Loma Linda University, they have been practicing locally since 2010 until they decided to open their private practice in Fullerton in January of 2015. Together they treat comprehensive cases by combining their skills, including endodontics, implants, and orthodontics. Their focus is family dental care-including treatment of pediatric patients with oral conscious sedation. When they are not at the office, they enjoy spending time with their three children, Rebekah, Lola, and Valentino, travelling to new places and exploring the outdoors. Dr. Rios grew up in Mexico and moved to California with his wife since 2010, he spends his free time hiking and mountain-biking the trails of southern California, gardening, and reading up on the latest tech gadgets or cars. Dr. Martinez grew up locally in Tustin, California, enjoys cooking, travelling, interior home decor, and doing arts and crafts with her kids. Dr. Rios and Dr. Martinez also enjoy going on "foodie adventures" and wine-tasting together.
