What is it really like to work with us to buy, sell or lease a property? Of course, we can tell you but we prefer to let our clients do the talking. Here’s a selection of real experiences and honest feedback that we hope will help you choose the best real estate agent for you!

Stephanie’s expansive knowledge of the realty market, high ethical standards, transparency and honesty, rare, are somethings we have never seen in our dealings with agents during our 18 years of frequent relocation in the Canadian Armed Forces. Her remarkable hard work, ingenuity, savvy research, superb and innate negotiating skills and willingness to get the best deal for her clients helped us to make quick decisions on the spot; she got us a beautiful house in the Kingston area for a great price. Easy to work with, Stephanie is a star in her class. This brilliant agent went above and beyond her brokerage responsibilities to help us get our newly purchased house cleaned, hook up utilities, and keep our redirected mails/packages safe until occupation. Linking us up with a reputable lawyer to close the deal made the entire process smooth and easy for us. As a spouse of a former military personnel, Stephanie kept all her promises until the end. We highly recommend her without reservation to anyone looking for the best deal in the Kingston geographical area. Once, again million thanks to you, Stephanie, for your dedication, trustworthiness and stellar negotiation skill sets.

Stephanie came highly recommended and we learned, very quickly after meeting her, why. She was highly responsive, reliable and kept it real for us. My family was in search of a particular home within a set price range and Stephanie worked very hard to find us exactly what we were looking for. At one point we visited a house that was above our price range and it wasn’t exactly what we had envisioned. But my husband and I were worried we wouldn’t find the exact home we wanted so instead, we were willing to settle and pay more than we had planned. Stephanie encouraged us not to over-pay, be patient and stay focused on finding our dream home. We truly can’t thank her enough for that! Not only did she find us our dream home, we purchased it for significantly below asking price. What real estate agent does that?! A very successful one who isn’t in the business to focus on her own profit, rather to help customers find exactly what they’re looking for. We highly recommend Stephanie to anyone!!


Jamie’s honesty, work ethic and integrity are the reasons I chose him for the sale of my house. He worked hard for me and not for his own interests while providing sound judgement and advice throughout. His knowledge and efforts were able to maximize the return I received for my home. His experience and expertise of the local real estate market are an asset to anyone thinking of using his services. I would recommend him to my own mother.

My husband and I are in awe at how easy & fast Steph made the process of selling our home. Steph is so personable (definitely in the right business), knowledgeable, timely, efficient & down to earth. We would most definitely use her services again in the future and be very confident recommending her to anyone in need of real estate services. We are extremely happy sellers who got over asking price for our home in a very short time. Steph was amazing doing all she could to make things safe for us as the sellers during the pandemic that is upon us … well done!!!


Thanks for selling my home quickly – I was happy to get more money than other agents told me it was worth!

Jamie is extremely knowledgeable about the subtleties in Kingston neighbourhoods. He is skilled at translating both wish list and lifestyle into features for your ideal property. More than anything, I found Jamie to be insightful and patient, which are important assets for any first time home buyers who are exploring various options. Jamie’s confidence set me at ease knowing that I would be successful in finding my home. Turns out it only took 5 tries! I can’t recommend Jamie highly enough if you are looking for a diligent, friendly realtor with strong negotiation skills and good contacts for home inspection and legal services. It’s clear that Jamie has earned my highest endorsement, and a big thank you for all his help along the way!
