Meet Your Tracy Dental Team

Dr. Liao


Dr. Janice Liao was raised in Stockton, CA, in the same neighborhood where our Stockton office is. She graduated from Lincoln High School in 1994 and attended UCLA, graduating with a Bachelor of Science in physiological science in 1998. Dr. Liao went on to earn her Doctorate of Dental Medicine from Temple University in Philadelphia, PA, in 2002.

Dr. Liao then returned to California to complete a year-long General Practice Residency at University Medical Center in Fresno. She worked as an associate for Dr. Kenneth Yi in Stockton and Tracy for six months in 2003 before establishing her home base in Dublin, CA. Dr. Liao enjoys working with patients of all ages and from different dental backgrounds.

Dr. Shiao


Dr. George Shiao was born in Taiwan and raised in Dallas, TX, so he is a big Cowboys fan! He attended Cistercian Preparatory School in Irving, Texas, before graduating with a Bachelor of Arts in history and biology from Washington University in St. Louis in 1995. In 1999, Dr. Shiao earned his Doctorate of Dental Medicine from Temple University.

Following graduation, Dr. Shiao worked in private practice in Pennsylvania and New Jersey while also serving as a clinical instructor at Temple’s dental school. He spent several years performing comprehensive oral rehabilitation for special needs patients at Special Smiles in Philadelphia. Dr. Shiao moved to California and practiced in the Bay Area shortly before marrying Dr. Liao in 2004. Dr. Shiao is also a clinical faculty member at the UOP School of Dentistry. He looks forward to working with you and your family!
