Cathlamet Dental was originally formed by Douglas Martin DMD, who practiced until November 2014 when Corey Blankenship, DDS purchased the existing practice. Dr. Martin had looked for over a year to find the right person to fit the community of Cathlamet. Dr. Blankenship is a graduate of the New York University, College of Dentistry. After graduating from NYU, Dr. Blankenship served as an active duty dentist for the US Navy, first with the Marines at Parris Island, South Carolina, and then aboard the USS John C. Stennis, an aircraft carrier stationed in Bremerton, WA. After completing his active duty service, Dr. Blankenship joined the US Navy Reserves with a US Marines Reserve unit in Portland, Oregon and worked as a general dentist in eastern Washington before coming to Cathlamet.
