General & Family Dentistry

Dr. Geoffrey Johnston
Dr. Geoff’s passion for dentistry began at a young age after spending a lot of time in the dental chair himself. Thanks to a positive and even fun experience with his orthodontist and dentist, he saw firsthand how impactful a compassionate approach to care could be. After hearing from friends and family who dreaded dental visits, Dr. Geoff made it his mission to change the way people feel about going to the dentist.
Dr. Geoff earned his Bachelor of Science degree from Western Washington University and his DDS degree from the University of Washington. Together with Dr. Niki, he is proud of what they have built at West Seattle Smile Co., a reimagined dental experience designed to be as comfortable, welcoming, and patient-centered as possible. The office offers a comfort menu with options like blankets, pillows, noise-canceling headphones, and under-eye masks, and is supported by a team that genuinely cares about creating an excellent patient experience.
What motivates Dr. Geoff most is the opportunity to help people smile every single day. Whether he’s relieving someone from dental pain or completing a full smile transformation, he feels grateful to play a role in improving both confidence and quality of life.
Dr. Geoff lives in West Seattle with his wife, Dr. Niki, and their two children. Originally from Olympia, he enjoys a wide range of outdoor activities, especially golf. Living and working in West Seattle has been incredibly meaningful to their family, and he values being part of such a close-knit, community-focused neighborhood.
