Meet Dr. Keith Gressell

Your Gig Harbor Dentist with World-Class Experience

Dr GressellFamily of doctor Keith Gressell.

Dr. Keith Gressell was born and raised in Scranton, PA (yes, the same Scranton as The Office!). He attended the University of Scranton and went on to graduate from Temple University School of Dentistry as a Doctor of Dental Medicine in 2005. After graduation, he was commissioned as a Captain in the U.S. Army, stationed in Landstuhl, Germany. During his time in the Army, Dr. Gressell served in three different theaters of operation, treating US Military members, contract personnel, and local nationals from Afghanistan, Benin and Iraq.

After completing his tour in 2012, he obtained his German Dental Approbation License and worked in private practice in Wiesbaden, Germany, that serviced military family members, US Consulate staff and Expats alike. While in Germany, he completed training to become a Nobel Biocare Certified provider and expanded his general dentistry experience in Oral Surgery and Implantology. Germany also inspired Dr. Gressell to incorporate an Overall Health approach to his dentistry, by combining his U.S. training with his experience working in a European environment, which introduced him to different methodology. This unique combination of philosophies has become the core of Dr. Gressell’s approach to private practice. He is always looking to adapt and improve the quality of care he provides, so he can better his patients’ dental health, well-being and lives.

In 2017, he moved to San Antonio, TX and worked in private practice with his wife, Jackie, for 2 years before eventually relocating to her hometown of Gig Harbor, WA in 2019. Dr. Gressell has 5 children that keep him busy at home: Madison, Sawyer, Ellie, Torsten and Delilah. He is a classic rock enthusiast, an avid sports fan, and a proud innovator – check out the dental suction device that he invented, called Linguaguard.

Dr. Gressell established Harbor Hill Dentistry and Airway Center in 2022 and is excited to bring exceptional patient care to the Harbor.
