Registered Dental Hygienist
“I couldn’t imagine working with anybody other than Dr. Calleros. She truly is an exceptional dentist and person whose ethics, integrity, and dentistry are a reflection of this. She is my mentor and I look forward to the many years to come that we will work together to help our patients obtain healthy smiles.”
Stephanie has been working alongside Dr. Calleros as her Registered Dental Hygienist for over 10 years. She and Dr. Calleros have a great partnership and work well together to provide the highest standard of care to all patients. Her love for dentistry started at a young age and it’s only fitting she has made a career out of it. She thoroughly enjoys being able to help her patients achieve total health by improving their oral health.
Stephanie received her Bachelors of Science in Kinesiology from San Diego State University and later attended Dental Hygiene School at West Los Angeles College in Culver City. She is also a Laser Certified Dental Hygienist and an active member of the American Dental Hygienists’ Association.
She takes a special interest in Laser Dentistry, taking advanced continuing education laser courses to stay abreast of current research and technology to ensure our patients are receiving the very best treatment available.
Stephanie is also a myofunctional therapist. This therapy helps patients with a variety of muscular and airway disorders.
Serving the community is important to her as well. Most recently, in September, she traveled to Guatemala to provide dental services to an impoverished community through the Open Wide Foundation. Each year she coordinates a day with local agencies such as Habitat for Humanity and the 1736 Family Crisis Center, where the office and other volunteers provide dental services to underserved families, who do not have access to regular dental treatment. She participated in Maria Shriver's Modern House Call for Women in Long Beach. Whether it be adopting families in need for the holidays or participating in charity fitness events which raise money for cancer, childhood obesity, and many other great causes Stephanie truly enjoys giving back to the community and helping those in need.
Outside of dentistry, Stephanie enjoys many fitness activities and challenging herself mentally. You can find her on a long bike ride along the coast, hiking up a hillside, training for a triathlon or her next marathon. Becoming a first time Ironman in 2011 is one of her most notable accomplishments. Her awesome husband, Jason, who owns Estrada Fitness, also located in El Segundo, supports her every step of the way. They first child, Elijah, was born in May 2014 and daughter Nylah was born in the Spring of 2017 . She loves the beach and the sun and couldn’t imagine living anywhere else but the South Bay.

"Working at Calleros Dental has allowed me to grow as a professional while connecting with my fellow El Segundo residents. It is the best of both worlds."
Dr. Calleros met Marissa through a long time friend and is thrilled to have on the Calleros Dental Team. She was introduced to the dental field by her dentist at a young age and instantly knew she wanted a career in dentistry. While attending California State University Dominguez Hills, where she received her Bachelor’s Degree in Sociology with a minor in Anthropology, she began her dental career. With over 20 years of continued dental experience, which includes working at the UCLA School of Dentistry where she was awarded employee of the year in 2010, she decided to take her career to the next level and pursue dental hygiene. This lead her to the West Los Angeles College Dental Hygiene Program, where she furthered developed her leadership skills as class President for two years. Finally achieving her goal of becoming a dental hygienist, she looks forward to many more years of providing the highest standard of care to each patient. She is also an active member of the American Dental Hygiene Association. In the future she plans to work towards her Masters in Dental Hygiene and become a dental hygiene instructor.
Near and dear to her heart is her family. She has been married to Ron (R.C.), her biggest supporter, for 16 years. Together they have two children, Mateo and Gabriella. Being long-time residents of El Segundo, her family is very involved in the community and schools. They are huge supporters of UCLA and attend as many Bruin events as possible. Go Bruins!
Wanting to give back to the community they are from, she and her husband have been running a non-profit organization called the Inland Empire Future Leaders, for past 13 years. Her dedication to this educational leadership program enables her to serve 150 high school-aged students and 75 staff members where she engages a diverse staff and plans and implements student and parent workshops focused on cultural awareness and educational success. However, her willingness to give back does not stop there and she volunteers each year at the Care Now LA Health Fair, where she provides free dental services to underserved communities.
Marissa looks forward to spending quality time with her kids and helping them at school. She embraces her hobbies which include reading, running to the beach and arts & crafts.
