Barkley Bastian, DDS

Barkley Bastian is a graduate...

Barkley Bastian is a graduate of the University of Washington Dental School where he received a Doctor of Dental Surgery degree.  He is also a graduate of the University of California Santa Cruz with a BA degree in Biology. His active lifestyle and love of the outdoors prompted him to move to Maui, Hawaii where he has established his private dental practice.

Dr. Barkley Bastian’s practice focuses on whole body health, restorative, biological, neuromuscular solutions, titanium and ceramic implants and LASER dentistry.  Dr. Bastian is a member of the IAOMT (International Academy of Oral Medicine and Toxicology.)

I love the patient that comes into our office for a second opinion because I know what we tell them is going to be completely different. I love the patient that comes in with the ever so common complaint that “I had this work done recently and it just never felt right”. We can often provide a solution that has these patients convinced that we just performed magic.

Dr. Bastian is enthusiastic about Water Sports such as Surfing, Stand-Up Paddling, Kiting, Windsurfing and Tow in Surfing.
