Meet The Doctor

Dr. Herrera has been practicing periodontics with a gentle touch and a commitment to excellence here on the Peninsula for many years. . She was born and raised in Reno, Nevada where her brother practices dentistry and where her father retired after practicing dentistry for 43 years. Being raised in a “dental family” fueled her passion for dentistry and serving her patients and treating them like family like her father did.  After graduating from the University of Southern California Dental Hygiene School,  she practiced and taught Dental hygiene at USC and in Barcelona, Spain. Dr. Herrera graduated with honors from University of the Pacific also known as Arthur A. Dugoni School of Dentistry. She also received clinical awards in both pediatric dentistry and periodontics. She went on to advanced studies in periodontology at the University of California, San Francisco.

In 1999 the San Mateo County Dental Society awarded Dr. Herrera with the Distinguished Service Award for her admirable contribution to the dental community. She has been an elected member of the San Mateo Dental Society Board of Directors and the Stanislaus Dental Society. Dr. Herrera served on the membership committee and on the Recruitment and Retention Task Force. She served on the committee to develop a new dental hygiene program in San Mateo County and has been editor for the California Society of Periodontists as well as serves on multiple committees of the American Academy of Restorative Dentistry. She is also a member of the Mid Peninsula Dental Society, San Mateo Dental Society, ADA, CDA, AAP, CSP, AARD and Pierre Fauchard Academy.

Dr. Herrera has built her practice centered on patient’s health and providing excellent periodontal treatment.   Her vision is to empower patients to elevate their oral and overall health by education and state of the art periodontal care. This approach includes listening, sharing information and preparing patients for treatment. She is especially passionate about providing care and keeping patients comfortable during and after treatment.  Her practice emphasis is oral care education, periodontal plastic surgery, regenerative procedures, microsurgery, and maintenance all delivered with kindness and compassion. Emerging science linking periodontal disease to cardiovascular disease, respiratory disease, adverse pregnancy outcomes, diabetes, cancer, Alzheimers Disease and osteoporosis is of particular interest to Dr. Herrera. She also collaborates with exceptional general dentists and specialists in order to deliver optimal treatment results. Dr. Herrera is passionate about continuing education for herself and her team. Dr. Herrera is kind, compassionate,  and easy to talk to.   She has dedicated her career to continually growing in her knowledge and clinical skills.  Values that are important to her are honesty, integrity, compassion, excellence and growing spiritually. 

Dr. Herrera is proud of her team and the kindness and compassion they show their patients. They are Julie:  Treatment coordinator; Kelly:  Administrative Coordinator; Oriana and Trisha: Registered Dental Assistants;  Lolly and Cassondra:  Registered Dental Hygienists.  

It is the friendly, caring and  attentive environment created by Dr.Herrera and her team that each patient appreciates and that sets the office apart. For years doctors have referred their patients to our practice because they know they will be well cared for.  They know Dr. Herrera will be honest and direct with their patients and will explain their diagnosis, treatment recommendations and options thoroughly.  They also trust that she and her staff will assist their patients from their first appointment through treatment with love, compassion and respect. 

Dr. Herrera has four children: Lauren, Kenny, Zachary and Carly. She also has five grandchildren: Braden, Mila, Jimmy, Lucas, and Vasi.  She is a devoted mother and grandmother and is passionate about her family and time with them.
