About Us: A Mother-and-Son Real Estate Team!
As a mother-and-son real estate team, we approach every client relationship with a deep sense of responsibility and commitment. Selling your home is not just a transaction—it’s one of the most significant financial decisions you’ll make, and we’re honored to guide you through it.
We pride ourselves on being conscientious professionals, effective communicators, and trusted advisors. With a foundation built on high integrity, exceptional customer service, and always putting your best interests first, we aim to deliver a seamless, stress-free experience.
Think of us as your financial advisors in the real estate world. We bring knowledge, expertise, and a proactive mindset to help you make informed and strategic decisions throughout the home-selling process. Our goal? To ensure you feel confident and comfortable every step of the way.
We also believe that exceptional service isn’t just about getting the job done—it’s about creating an experience that earns your trust, your 5-star review, and your future referrals. And yes, we’ll sprinkle in some fun and humor to make the journey enjoyable!
Meet Catherine
Catherine’s work ethic was shaped at an early age, starting her first job at 14 in her family’s retail store in Keene, NH. Her father’s advice about honesty, diligence, and prioritizing customer service remains at the core of her career today.
As a D1 walk-on athlete and former corporate real estate executive with a Fortune 100 company, Catherine knows what it means to earn her place and deliver results. With over a decade of experience in interior design and corporate real estate, she transitioned into residential real estate and has been a consistent top producer for 18 years, working with Keller Williams and other leading firms.
Meet James
James joined the team in 2020, bringing financial savvy, technical expertise, and an upbeat personality (all 6'5" of it!). His strengths perfectly complement the team’s dynamic, allowing him to focus on guiding buyers through the process of finding their dream home.
Outside the Office
When we’re not working, we’re embracing an active and healthy lifestyle. Whether it’s running, lifting, spinning, or practicing hot yoga, we love staying on the move. Catherine starts her mornings walking her two beloved rescue dogs on their 3-mile trek, a ritual that sets the tone for the day.
James is an avid golfer, steadily working his way back to scratch golfer status after his recovery from Lyme disease, and he also has a passion for cars.
We can’t wait to meet you, learn about your goals, and help you take the next step in your real estate journey. Let’s make it happen together!
