Dr. Greg Appelt

President & Founder

Greg is a born entrepreneur. It’s quite literally in his blood. He comes from a family of entrepreneurs. Before he started medical school he’d already run two small successful businesses. After receiving his medical degree from the University of Manitoba and establishing his own practice as an allergist, Greg decided to build his own medical building. After its completion he started RISE (formerly Appelt Medical Developments). He wanted to help doctors and business owners across Western Canada create equity by owning their own office building in the same way he’d been able to. A driven and focused leader, Greg has a knack for bringing out the best in the people around him. When Greg is off the clock, he can be found snowboarding, wakeboarding and enjoying time with his wife and three kids.


Justin Bierwirth


Justin’s passion for real estate development began in Calgary. After receiving degrees in both Commerce and Kinesiology, he went on to complete his CPA, CA designation. After articling with Collins Barrow LLP, Justin spent time in senior financial roles in both public and private enterprises.   

It was, however, while working as a senior executive for a condo development company in Calgary that Justin fell in love with real estate. His career path took him to Kelowna where he became executive VP of a large private real estate company and expanded his expertise further into other asset classes including commercial, office and hotel. Through his experiences, Justin has developed leadership skills beyond the traditional financial executive role and is described by co-workers as authentic, honest and ambitious.

When not working, Justin can be found with his wife and three kids on the slopes or around the beach. He is active within the community by participating at Board levels or just coaching his daughter’s basketball team.
