Client Reviews
What my clients are saying
“Katie is AMAZING!! As first time home buyers, the process was incredibly intimating, but Katie was by our side the whole time. She put up with multiple weekends packed full of showings and helped us figure out exactly what we wanted. Once we knew what we wanted, Katie found us the perfect place. It was a house that we hadn’t even seen in our searches, but she saw it on another showing and called us that day to look at it. Turns out, she was right, and it was the PERFECT house! Katie went above and beyond throughout the process and was so patient and knowledgeable. Would highly recommend working with her!”

“Katie was my realtor when I purchased a home and when selling my home. First, she is incredibly knowledgeable and experienced with buying and selling in the area. She knows how to navigate a tricky market and works very hard to complete the sale. I bought a home in 2021 in a very competitive market and sold my home in 2025 when things slowed way down. Both times I was able to close quickly despite the challenges of the housing market. A huge thanks to Katie for making it all happen. I have nothing but great things to say and will always recommend her to anyone looking to buy or sell.”

“We had the pleasure of working with Katie Portenga to sell our home, and we couldn’t be more grateful for her expertise and steady guidance. From the start, Katie was knowledgeable, responsive, and deeply committed to helping us navigate a tricky market and a particularly challenging prospective buyer. Katie remained calm, professional, and solution-oriented throughout the entire process—even when things got weird. Her communication was always clear and timely, and she helped us feel confident every step of the way. She went above and beyond to protect our interests while keeping things moving forward. Thanks to Katie, what could have been a stressful and uncertain process ended in a successful sale and a smooth closing. We highly recommend her to anyone looking for a smart, skilled, and truly dedicated real estate agent.”
