Theresa M. Sabo

Director of Operations

Theresa is the Director of Operations for British Columbia and joined our group of Colleges in 2019 with over 25 years of private career college experience. Her commitment to raising the standards of post-secondary education has been her focus since she founded her first college on Vancouver Island in 1995. Her unique approach to hands-on learning and presenting programs in a professional, virtual environment earned her a nomination for Entrepreneur of the Year for Innovative Business Concepts.

In 2009 the Ministry of Advanced Education’s Private Career Training Institutions Agency (PCTIA) invited Theresa to lead the Agency’s Accreditation teams as Chairperson, where she spent almost 10 years chairing over 80 audits and reviews, with some of the Province’s largest and most complex institutions in her portfolio. Theresa also worked with PCTIA’s Accreditation Manager and Registrar to re-structure and re-design the accreditation process and reporting documentation. When the Ministry restructured its regulations, Theresa switched to consulting – working with private training institutions to achieve the standards required to attain or maintain status as a Designated Learning Institute In BC.

In her spare time Theresa works with the National Association of Career Colleges presenting at their Management Academy sessions and is an active member and past co-chair of the World Health Organization’s Patients for Patient Safety Program in Canada – speaking across the country and on the TEDx stage about patient safety and the impact of medical errors.

Instructor/Senior Education Administrator

Justyna is Granville College’s Senior Education Administrator.

She and her teammates have developed and implemented an effective VTA training program to allow students to enter the veterinary industry with the necessary skills to provide the highest standard of care to both patient and client.

When Mandy’s not working, she enjoys spending time with her husband, young daughter and “Libby“. They can often be found biking around town, hanging out at the beach, ortravelling to eastern Canada to visit family in her hometown in Nova Scotia.
