My name is Toriyana Dickens, I grew up in Sacramento playing competitive soccer and dancing before leaving for southern California to attend Loyola Marymount University as a Biology major. I then completed my dental hygiene degree at Chabot College in 2009. Working as a waitress during college helped me develop my patience and customer hospitality skills. What drew me to the dental field was my desire to educate, understand and improve overall health and above all connect with people. I am very passionate about my career and continue to grow and challenge myself as a person and hygienist everyday. In my personal time, I enjoy researching, reading, dancing, camping and motorcycle riding through the canyons. I look forward to getting to know you and do appreciate any constructive feedback that would help me and my teammates better serve your needs.


Hi my name is Cynthia Rivera, I am a full time Dental hygienist here at Sherman Oaks Dentistry. In addition to my dental hygiene license, I have an extended dental hygiene license (RDHAP) that allows me to serve the homebound, special needs, and Geriatrics patients that are not able to travel to a conventional dental office. I am an active volunteer at Remote Area Medical (RAM), this association of volunteers provides free medical and dental services to those that cannot afford them. The two loves of my life are my two sons Elliot who is 18 yrs old and Seth who is 8 years old. My favorite hobby is running. I have run many marathons, including the prestigious Boston marathon (one must qualify to be able to get an entry at this marathon). I enjoy dancing, music, movies, the beach and mountains. I try to live by “the Golden Rule” my interpretation is “Treat others as you consent to being treated in the same situation”.
