Get to Know

DR. Jeff Yoshihara

Dr. Jeff Yoshihara was born and raised in Union City, CA. He chose to stay local and attended UC Berkeley for his undergraduate education, earning a degree in Integrative Biology before moving down to Southern California to attend the UCLA School of Dentistry. After graduating, Dr. Jeff decided to move back to the Bay Area and has been practicing as a general dentist ever since. 

Dr. Jeff believes that patient education, understanding, and comfort are just as important as the quality of dentistry being provided. He takes the time to discuss and review all treatment options with his patients, working collaboratively to design a treatment plan that best meets each individual patient's needs.  

While he is a perfectionist (an ideal quality to have in a dentist), Dr. Jeff is also very relaxed and can usually be found smiling or heard laughing around the office. His hobbies include weight lifting, photography, fashion, and napping.

Dr. Haleh Fazeli

Dr. Haleh Fazeli was born and raised in Southern California. Her caring and warm demeanor make her patients feel at ease in her care.  While she enjoys the artistic side of dentistry, she feels that prevention and patient education are the keys to a healthy smile.  

After attending the University of California, Irvine, she moved to the east coast to pursue dentistry and completed her dental degree at the University of Maryland School of Dentistry. Following graduation, she completed a General Practice Residency at the VA Hospital in Philadelphia to hone her skills in hospital dentistry.  She has served in multiple VA hospitals on the east coast and still maintains a part time practice at the Palo Alto Veterans Affairs Hospital.

 Dr. Fazeli believes in the importance of continuous learning and takes courses in order to stay up-to-date with the current technologies. She is a member of the ADA, CDA and Mid-Peninsula Dental Society. While not caring for her patients, she enjoys being active and spending time with her husband and two children.

Dr. Colin Au

Dr. Au is a proud native of Northern California and a graduate of San Francisco’s renowned University of the Pacific Arthur A. Dugoni School of Dentistry. From the start, Dr. Au knew he wanted to open his own practice one day. In an office of his own, he knew that he would be able to provide his patients with the quality of care they truly deserve. 

At Peninsula Dental Excellence, Dr. Au’s goal is to provide caring, cutting-edge dentistry so each patient receives comfortable, efficient care. This means that Dr. Au takes individual time with each patient to formulate a personalized treatment plan, as well as to reassure them and make them feel comfortable. He always listens to his patients’ concerns and questions and offers straightforward, informative explanations about treatment options and procedures.

Dr. Au loves seeing his patients leave healthy, happy, and enjoying their smiles. Outside the office, Dr. Au values spending time with friends and family, travelling, and racing go-karts.
