Meet Our Friendly Doctors
George Shiao, DMD
Dr. George Shiao was born in Taipei, Taiwan. He came to the United States as a young child and was raised in Dallas, Texas. He attended the prestigious Cistercian Preparatory School in Irving through high school. Dr. Shiao’s close ties to family back in Taiwan have helped him retain his native languages of Mandarin Chinese and Taiwanese.
Dr. Shiao completed his undergraduate studies at Washington University at St. Louis, where he studied biology and history. Four years later, in 1999, he earned his Doctorate of Dental Medicine from Temple University School of Dentistry in Philadelphia, Pennsylvania, which is the second-oldest dental school in continuous existence in the U.S. Dr. Shiao was awarded the International College of Dentists Award of Excellence out of his graduating class, and he continuously strives to maintain this high level of excellence in his practice of dentistry.
Following graduation, Dr. Shiao worked in private practice in Pennsylvania and New Jersey. He also served as a part-time clinical instructor at Temple University’s dental school while interning for the Oral and Maxillofacial Surgery Service at Helene Fuld Hospital in Trenton, New Jersey. He spent the next several years performing comprehensive oral rehabilitation for special needs patients at Special Smiles in Philadelphia.
A year before his marriage to Dr. Janice Liao, Dr. Shiao moved to California, where his parents had settled after living in Texas. He fell in love with the Tri-Valley area and decided that Dublin was where he hoped to live, work, and raise a family.
In 2007, Dr. Shiao was appointed as a part-time faculty member at the University of the Pacific Dental School Graduate Clinic at Union City. He enjoys teaching, as well as the additional opportunities to learn the most current methods and technology in dentistry. Dr. Shiao has completed hundreds of hours of continuing education, and he is a member of the Southern Alameda Dental Society.
Although Dr. Shiao now resides in Dublin, he considers himself a true-blue Dallas Cowboys fan. His other interests include ethnic cuisine, European cars, and his daughter, Sofia, and son, Troy.
Janice Liao, DMD
Dr. Janice Liao was raised in Stockton, California. She earned her bachelor’s degree in physiological science from the University of California at Los Angeles. While working as a dental assistant, she decided to pursue dentistry as a career. Dr. Liao then achieved both her Doctorate of Dental Medicine and her Master of Business Administration from Temple University School of Dentistry. She also met her husband, Dr. George Shiao, while studying at Temple University.
After graduating in 2002, Dr. Liao completed a one-year residency in General Practice with a focus on Hospital Dentistry at the University Medical Center in Fresno, California. She spent the following year in a family group practice in Stockton, where she could be closer to her family. It was shortly before her marriage to Dr. Shiao that she settled in the Tri-Valley area.
Since then, Dr. Liao has committed herself to dental excellence. She prides herself in quality dentistry with a gentle touch. She has the smallest hands of any practitioner she has ever met. Even extra small gloves are sometimes too big for her! You will often hear her say, "We stand behind our work." This is because she believes in treating others like she wishes to be treated. Rest assured, you will be comfortable and well taken care of at Dublin Smiles.
Of her many accomplishments, Dr. Liao considers her role as a mother to be her greatest and most important. Because family is such a priority for her, she understands the importance of trust, honesty, communication, and support in secure relationships. Her dedication to these values helps set her apart, and it leads to the development of long-lasting relationships with patients. Dr. Liao takes pride in being a doctor you can trust and count on.
Dr. Liao is a member of the Southern Alameda Dental Society, which is an appendage of the California and American Dental Associations.
