From the time I met her to the time I was done with her. She was great, very professional and took no corners or spared any time for anything I asked and showed me every house that I needed. I would greatly send her a referral to anyone we still stay in contact and she’s a great agent. - Gerry

Loved Denise! She was very patient and professional. This was our father's estate . A difficult and emotional time. We could not have had a better person to handle the sale. Highly recommend. - ROBERTA I Kalar

Reply:    Bobbie you and your family have been such an incredible part of my business, and the best part of it all is that somewhere along the way, you became much more than clients.. you became family friends. I am so grateful for each of you and fortunate too have worked alongside each of you.

Home Purchase in Sarnia | Apr 2018

can’t say enough good things about Denise Cortez\. She was fast, professional, easy to communicate with, and always had my best interests in mind when I bought my home\. She never took shortcuts and made sure everything was handled properly\. What truly sets Denise apart is that, even seven years later, she still keeps in touch through invitations to gatherings and thoughtful messages around Christmas, Father’s Day, and other special occasions\. She genuinely cares about her clients long after the transaction is complete\. I highly recommend Denise to anyone buying or selling a home, and she would be my first call every time\. ⭐⭐⭐⭐⭐ - Gerry

Reply:    Wow! Thank you so much Gerry for the thoughtful review. Hard to believe it’s already been that long. Hope you and your beautiful little family are doing well.

Working with Denise when buying and selling our house was a wonderful experience. Denise has a lot of knowledge of what’s for sale and what people are looking for. We went back and forth for a couple months to ensure we were getting our must have’s on our list. We had such a great experience with Denise that we used her to sell a family members home.I would recommend Denise again! - Kaylee Wood

⭐⭐⭐⭐⭐ We’ve had such a great experience with her over the years! She has helped me with the transition through three different homes, and every time she has been professional, knowledgeable, responsive, and genuinely supportive. One thing I especially appreciate is being able to communicate with her in Spanish; It has made the whole process more comfortable and convenient, especially when discussing important details. Having a realtor we already know and trust has made every move so much easier. I would absolutely work with her again and highly recommend her! - cardenas adriana

Reply:    Thank you for being such a loyal client and friend. Your support means so much. I have enjoyed every time we’ve worked together and look forward to the next one. Best of luck with the move and hope to help you out again the future. Mil gracias.

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.

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.
