About Thea
For me, real estate is never just about buying or selling a property—it’s about guiding people through meaningful life transitions. Whether you're stepping into a new chapter or closing one, you deserve someone who listens deeply, understands your goals, and walks beside you with honesty, care, and heart. That’s the kind of experience I strive to create for every client.
I know how overwhelming the process can feel. There’s a lot to consider, and often, even more to learn. That’s why I focus on making things simpler, clearer, and more personal. I bring a strong work ethic, deep local knowledge, and a genuine commitment to serving you in a way that feels right for you. What matters to you, matters to me.
I also understand that life doesn’t always allow for a sit-down meeting. Whether you're out of state, juggling a busy schedule, or navigating unexpected circumstances, I make every effort to be flexible and accommodating. My goal is to understand how you work best, and then shape my process around that. I believe our most important role as agents is to be educated—and to educate—so that you can make confident, informed decisions. I stay current on both local and national market trends, and I take the time to walk you through what to expect—not just today, but in the future. When the unknown becomes known, the stress starts to fade.
Before I committed fully to real estate, I spent years in the building trades and banking industry. That experience gave me a solid foundation for understanding homes from the inside out—and the financial decisions behind them. It’s helped me guide clients with clarity and confidence through every step of the process.
And then there’s Blu—my Golden Retriever and loyal copilot. Blu has a gift for making people feel instantly at ease. Whether he’s greeting you with a wagging tail or quietly sitting nearby during a showing, he brings a sense of calm and joy that helps break the ice and soften the stress. Clients often tell me that Blu makes the experience feel more relaxed, more human, and even a little more fun. He’s not just part of my life—he’s part of my business.
My husband Jim and I have called Merrimack, NH home since 1993, and we’ve loved every minute of it. Jim’s a New England native, originally from Massachusetts, while I grew up in the San Francisco Bay Area. I’ve always had a love for the outdoors, and New Hampshire’s natural beauty won me over completely. Growing up, my family was all about ATVs, motorcycles, and carpentry—so I bring a little city flair with a strong appreciation for hands-on work and country living.
At the heart of everything I do is connection. I believe that to truly guide someone, you have to listen first. That’s where I begin—by getting to know you, your story, your goals, and what home really means to you. Whether you're a first-time buyer, a seasoned investor, or somewhere in between, I’m here to make sure you feel supported, informed, and empowered every step of the way.
My lifetime experiences working in the residential building trade and banking industry, coupled with a solid work ethic brings value to anyone looking to make a successful solid real estate transaction. I originally got licensed in 1996, however, really got serious in 2020-21 and achieved the International Diamond Award putting me in the top 12% in sales volume in 2021, 2022, 2023 & 2024 out of 96,000 agents.
Buying or selling your home is very personal. I know you must have questions, so lets talk out about your options.

From my first conversation with Thea Knust to the final closing, I felt confident I was in the good hands of an exceptional realtor. As an out-of-state seller of a home in Nashua, I needed a realtor who would stay in touch with me on a frequent basis to answer my questions and to keep me abreast of new developments. Although I knew this was not the case, Thea made it seem as though I was her only client. She was highly attentive, focused and responsive regardless of whether it was day or evening, weekday or weekend. Every home has a story. She took time to listen to and honor our story and to understand the goals in selling the home. Her knowledge of the local real estate market and ideas about how to best promote the sale of the home proved to be invaluable. Her helpful suggestions and solid preparation upfront led to multiple offers within a few days of being on the market and to a successful closing a few weeks later. I highly recommend Thea to prospective sellers and buyers searching for a top-notch realtor to help them accomplish their goals.

Thea was amazing and is one of the best real estate agents I've worked with. From start to finish she was on top of everything, quick responses, super knowledgeable and always a good attitude. I will definitely use her again and recommend her.
