Crisanta Alzona, DDS

Crisanta Alzona was born and raised in southern California. Inspired to become a dentist by watching her mother, also a dentist, she strives to ease her patients’ pain, improve their dental health, the appearance of their smiles, and ultimately their quality of life. “Dr. Cris” received her Doctorate of Dental Surgery from the University of California, San Francisco in 1998 and her Bachelors degree in Biology from Chapman University in 1993. It was at UCSF that she did research in Alzheimer’s disease and how to care for and address the needs of our elderly patients. At UCSF she also had the opportunity to assist in general and specialty clinics giving her a better feel for all aspects of creating an operable and efficient dental team. As a private practitioner she volunteers extensively in the Su Casa league for underprivileged patients.

In the ever-changing field of dentistry she knows how important it is to provide her patients the most current, technologically advanced, and personalized care possible. To fulfill her commitment to you Dr. Cris thrives on continuing her education advanced dental courses including Invisalign orthodontic application and treatment,  the Seattle Institute of Dentistry’s advanced study of occlusion (the relationship of teeth and how to form a better bite), and the treatment of a worn dentition (when a bite relationship has caused problems over time).  Dr. Cris is an active member of the American Dental Association, the California Dental Association, and the Orange County Dental Association.

She and her husband, also a dentist, raise their two daughters here in Orange County. She spends most of her time continuing her education spending quality time with her family but squeezes in biking and cooking whenever she can.

David Levitt, DDS, Oral Implantologist

Dr. Levitt is our in-office Dental Implant Specialist. Dr. Levitt’s extensive resume began when he graduated from the University of Southern California School of Dentistry in 1977. He then attended a postgraduate program at USC/LA County General Hospital in internal medicine, physical diagnosis, and cardiology designed to qualify dentists to do admitting history and physicals for patients who would need hospitalization for major dental treatment. In 1980 He started a hospital based general practice in Fountain Valley, California. At that time Fountain Valley Regional Hospital was the busiest trauma center in Orange County. His practice consisted of general dentistry, dental trauma, and dentistry for medically compromised or handicapped patients who had to be treated in a hospital setting. I quickly realized that conventional dental rehabilitation was inadequate for many of these patients. In order to better help his patients, he began investigating the then new field of oral implantology and subsequently attended formal training at Loma Linda University, the Medical College of Georgia, and the Misch Institute. Dr. Levitt travels the US. conducting advanced education seminars for general and specialty dentists. He is an author, lecturer, clinical trial participant and evaluator, and a practitioner. His practice is now limited to oral implantology and related procedures such as bone grafting and implant restoration.

Dr. Levitt  routinely volunteers his skills to the less privileged and spends his free time enjoying his family, including a new Grandbaby. To get further information on Dr. Levitt, please visit his personal website at drdavidlevitt.com/CV.html.
