Karen McKiernan - Metrowest Realtor
After buying, renovating and selling homes with my husband for many years, I realized that my passion for design had evolved into a passion for real estate. Now professionally, I having the pleasure of helping others. My goal is to elevate the experience of buying and selling for my clients. I understand and appreciate that the home buying process is more than just a transaction and that finding the right community or "your people" is just as important as finding the right house. 

As a Realtor®, I have been recognized as one of the Top 10 Buyer's Agents at ERA and received the Circle of Honor Award, as well as the prestigious 100% award through Realty Executives for my sales production.

And as an Executive with Realty Executives Boston West, my skills and knowledge go hand in hand with a superb marketing team, along with mortgage services, staging consulting, attorneys and the latest technology in real estate tools for my sellers and buyers. In short, I work with an amazing team that will help streamline your transaction every step of the way!

If you are thinking of buying or selling a home in the MetroWest area, let's sit down over a cup of coffee and chat more about your specific needs and how I can help you achieve those goals. 

"Special shout out to Karen Mckiernan, our amazing Realtor and friend, who not only worked relentlessly to sell our house for top dollar on short notice last year, but pulled a rabbit out of her hat bringing this home to us before it was even on the market and helped us close quickly and painlessly. You're the best Karen, we cant thank you enough!

"And I want to thank my beautiful friend and realtor, Karen McKiernan Kolterjahn, for all her help in this emotional and incredible life changing moment..."

Carolyn Adams Kirk, Natick, MA 2018

Karen did a great job selling our house. Her instincts on staging and pricing were right on, and her team worked like a well oiled machine. She worked hard to market our house and follow up on prospective buyers. Karen stayed involved and kept us informed through the whole process, even taking care of things such as the fire inspection. We had an excellent offer within days of going on the market, and the process went smoothly through closing.
