You are entitled to use any title, letters or phrases granted to you by an educational institution for the purpose of identifying yourself as having completed a specific level of training. If you use Dr., you must also include the terms physical therapy so it is clear you are a doctor of physical therapy. DPT is not a recognized title or initial for a licensee. The Board recommends that you use the term PT after your name to indicate that you hold a license to practice. You can then list educational degrees after PT.
