No, even though you have earned the credential physiotherapists cannot use the title doctor or the short form Dr. when assessing or treating patients.
Dr. should not appear on anything a patient would receive or see during their patient experience.
The Restricted Titles, Credentials and Specialty Designations Standard directly prohibits its use in the provision of care.
Physiotherapists are able to use the title Dr. in non-clinical settings such as research or academia, or after their protected title. e.g. Mark Stewart, PT, PhD Psychometrics, DPT.
