Mark from CIC was an excellent speaker—knowledgeable, engaging, and very practical. He shared valuable real-world insights and explained everything in a clear and easy-to-understand way. I really enjoyed the presentation and learned a lot. Highly recommend attending any event where Mark is speaking!

I can’t say enough good things about GC Realty and the level of service we’ve received. Throughout the entire process, they were responsive, professional, and genuinely cared about helping us. Every question or concern we had was handled quickly, and they always kept us informed. I especially want to recognize Shania Gilharry. She went above and beyond to help my family with every issue that came up. Whether it was resolving a maintenance chargeback, helping with account questions, or finding solutions that worked for us, she was always patient, kind, and proactive. It truly felt like she was advocating for us every step of the way. Excellent customer service is hard to find these days, but Shania made the entire experience stress-free. If you’re looking for a property management company that genuinely cares about its residents, I highly recommend GC Realty. Thank you again, Shania, for everything you’ve done for our family!

11 months of leaks, bandaid fixes, and incompetence. Two separate leak issues were never fully resolved. Two flooding incidents left over 5 inches of standing water for over a week. Videos attached. Avoid GC Realty.
