Hours of Operation

CDA’s office is open for business but closed to visitors.

The College of Dietitians of Alberta (CDA) office is practicing ‘social distancing’ and has closed its doors and will establish a virtual office. This allows us to ‘stay open for business’ with staff available by email or by phone during regular business hours. College office hours are Monday-Friday from 9:00am to 4:00pm. If we are unable to assist you when you call the main office number 780-448-0059, please leave a message or send an email. We will address all questions or requests as soon as we can. Please contact Lisa Omerzu to discuss options for mail/delivery.
