Sue Liethen D.D.S.
Dr. Liethen received her Doctorate of Dentistry from Marquette University in 1988. After practicing as an associate for three years in Southern California she settled into her current location in Carlsbad. As a Wisconsin native, sunny California was a welcome change. Dr. Liethen is a member of the American Dental Society, the California Dental Society, and the San Diego Dental Society. Dr. Liethen is on the Advisory Board for the Palomar College Dental Assisting Program and has been a teaching office for dental assisting students for the past 26 years. In addition to volunteering her time with students, Dr. Liethen has been donating services through Dental Lifeline Network since 2016.
Dr. Liethen enjoys traveling, gardening and entertaining in her spare time. She is very proud of her son, Tyler, who is a flight instructor in Denver, Colorado.
