Who is

Born and raised in Niagara I have witnessed the tremendous change and growth that’s transformed the area into one of Ontario’s most sought-after destinations. Returning to St. Catharines after more than a decade in the Toronto area I took the expertise gained from in a career of sales and turned toward my passion - Real Estate. My exceptional knowledge of the Niagara real estate market, coupled with my seasoned insider’s expertise having built, lived in and sold numerous properties throughout the area makes me the unequivocal go-to resource for all your real estate needs.

Offering my clients concierge-style customer service when they are looking to sell or buy houses for sale in Niagara is one of the ways I set myself apart. When you choose me as your REALTOR® you can expect thorough and thoughtful services by way of a personalized approach to real estate.

The personal touch I give to your real estate transaction starts with attention to detail, such as ensuring “For Sale” signs are well lit when listing homes during a season of low daylight. I also construct Open Houses for unique sets of buyers and provide sellers with valuable feedback on their house as a result of this and other advertising efforts.

For Sellers

For clients looking to sell their home, I specialize in curating a selection of interior design pieces for home staging. I also create videos and virtual tours that capture all the best angles of your home which are then featured through a variety of mediums such as unique brochures, social media and MLS®. I’d love to offer my guidance and provide you with a selection of trusted service providers as you go through the many nuances of moving. This includes preferred professionals such as mortgage advisors, lawyers and insurance agents, as well as necessary trades workers who are precise painters, trustworthy movers, and of course landscapers who will make sure you smile every time you pull in the driveway.

For Buyers

Alternately, as your Buyers Agent, I will apply the same concierge-style services and high level of detail to the task of finding you the right home in Niagara. For buyer clients, I preview properties to ensure suitability and value based on their criteria, resulting in time and money savings for clients. By conducting research on comparable properties, I work to ensure you don’t overpay for your dream home. Being your REALTOR® also means making myself available to you, my buyers, around the clock. Once we’ve negotiated a winning offer, I’ll take on the work of ensuring home inspections are scheduled and land surveys are completed as necessary. For the grand finale, closing day, I’ll be with you to ensure expectations and all prior agreements have been met.

Let’s have a conversation about starting my concierge-based real estate experience for you.

What They're Saying.

As a first time home-buyer, Karen was extremely helpful in walking me through the process in finding my first home. Always available, and ever patient she made it very easy to narrow down my search in such a tough market.


Karen McMullin is an excellent real estate agent and I would highly recommend her services to anyone seeking to purchase or sell a home in the Niagara Peninsula.

Karen is a true professional, offering not only expert guidance and efficient service but also personal attention and understanding on a human level, which is truly a rare find in today’s world.

As first time home buyers, we were impressed by Karen’s wealth of information on market trends, and her ability to offer tips on new listings before they came on the general market, giving us the inside track on new, exciting properties.

We also highly appreciated the viewing tours she set up for us, which were well worth the drive down from the GTA. She instinctively knew which houses would be most appealing to us and expertly and objectively highlighted the pros and cons of each place.

Karen is not a pushy agent. She connected with us on a personal level and showed incredible understanding of our needs as jittery first-time buyers. She was always there with a quick answer at any time of the day or night and showed true compassion as we went through the ups and downs of our own decision-making process. In fact, after our experience, I feel proud to say that Karen is now our trusted friend, not just a professional in her field.

Whether you are first time buyers like us, or seasoned market pros, Karen’s services, expertise, and attention can make buying or selling your home an awesome experience.

Hello Karen

I just wanted to tell you how much I enjoyed working with you as our Real Estate agent. Yours efforts went above and beyond, with the open house just for the neighbours to come through.

I loved your signage. No one could miss that sign even in the dark with the solar lights shining directly on it. We had so much traffic through, due to your excellent advertising, and the feedback after each on was something that I had not experienced before.

Thank you for always being available to take us through a house when we wanted to see one. Our whole experience with you was amazing, and I never saw you without a giant smile on your face.

Thanks for being our agent, and hopefully now, our friend.
