Home Sale in Sarnia | Dec 2025

Denise Cortez was an absolute pleasure to work with. She is very honest, knowledgeable, and always gave us the best advice throughout the process. Her understanding of the market was spot on, and her pricing strategy was exactly right. She was extremely responsive, easy to communicate with, and genuinely pleasant to work with. Most importantly, she successfully sold our home during a time when the market wasn’t great, which speaks volumes about her expertise. We couldn’t have asked for a better agent. - Jelica Ariganello

Reply:    It was truly my pleasure. Wish you both all the best.

Home Purchase in Sarnia | Oct 2018

Talk about going above and beyond. I was open to all scenarios; new, a fixer upper, tear down and rebuild, lot and build, flip, etc. As such I wanted to see 90% of what was on the market, and she set up all the showings. I am not embellishing when I say she showed me over 85 houses. Truly dedicated and always cheerful and knowledgeable. I was first to see many places as soon as they were listed. I would definitely recommend Denise for helping you find your dream home. - Mark McCabe

Reply:    Mark thank you for the lovely review. 88 homes, you still hold the record ;) hope you are doing well.
