Meet Dr. Siri Ziese, DDS

Dr. Siri Ziese is the general dentist and owner of Ziese Family Dentistry. Since her early high school aspirations, dentistry has been a means for Dr. Ziese to raise peoples’ spirits by restoring their smiles. Dr. Ziese grew up in Grizzly Flats, just outside of Placerville, California and graduated from Loma Linda University’s School of Dentistry in 2007.


Dr. Siri Ziese, DDS has been providing dental care to the families of El Dorado County and beyond for over 10 years and enjoys being her community’s local dentist.  Dr. Ziese grew-up in the town of Grizzly Flats, just outside of Placerville, California.  She fondly remembers attending Pioneer Elementary School, Middle Creek Middle School, and El Dorado High School.  She spent much of her childhood living a simple life near the El Dorado National Forest, as well as strolling down Main Street, Placerville where she enjoyed the occasional ice cream or local movie.  During high school, Dr. Ziese excelled at her studies, advanced in track and field, and participated in the local ROP dental assisting program where she quickly gravitated towards a career in dentistry.  She also served as a dental assistant for Dr. Mitchell Goodis, DDS, who he helped nurture Dr. Ziese’s passion for dentistry.

Following high school, Dr. Ziese attended Pacific Union College in the Napa Valley where she earned a Bachelor of Science in Chemistry.  She graduated Magna Cum Laude and was quickly accepted into Loma Linda University’s School of Dentistry.  While attending college she met her future husband, Josh Ziese, who now works for the California State Water Board.  Dr. Ziese enjoyed dental school and excelled in her professional training.  However, if Dr. Ziese wasn’t in class or studying, then she was at Disneyland or the Santa Monica beach with Josh.

Dr. Ziese graduated from Loma Linda University in 2007 with a Doctor of Dental Surgery degree.  Immediately following her graduation from dental school, Dr. Ziese married her college sweetheart, Josh Ziese, and both backpacked through Europe for 2 months as their honeymoon.  Both Dr. Ziese and her husband have a tremendous love for travel and Dr. Ziese especially enjoys new and creative foods. Following their honeymoon, Dr. Ziese and her husband returned to the Placerville area where Dr. Ziese began her career as an associate dentist for Dr. Goodis.

Over the course of the next 10 years, Dr. Ziese would provide dental care to the disadvantaged patients served by Dr. Goodis at Diamond Springs Dental Center. She would also have 2 kids, help Dr. Goodis open a second dental practice named Pleasant Valley Dental, and continue her other hobbies such as traveling, camping and the occasional trip to Disneyland.  During this time, Dr. Ziese was also awarded the Student Loan Repayment Grant from the California Dental Association for providing much needed dental care to disadvantaged communities.  For Dr. Ziese, dentistry has always been a means of raising people’s spirits by restoring their smiles.

In 2018 Dr. Goodis retired and sold Pleasant Valley Dental to Dr. Ziese.  In July of 2018, Pleasant Valley Dental was renamed Ziese Family Dentistry and Dr. Ziese assumed ownership of this thriving practice, which had been serving Placerville and the surrounding communities for over 8 years.  Dr. Ziese is now continuing the health legacy created by Dr. Goodis and is further emboldened to provide quality and compassionate dental care to the families of El Dorado County.  However, when she’s not working, Dr. Ziese continues to raise her kids with her husband Josh while also enjoying hiking, running, cooking reading and the occasional trip to Disneyland.
