I had an exceptional experience working with my Rigel. From the very beginning—even when I first started looking at homes five years ago—he was incredibly patient, supportive, and understanding. When I had to put my home search on hold, he never pressured me, and when I was ready to jump back in, he was right there to guide me every step of the way. What truly impressed me was how Rigel made this deal happen. At one point, I thought the house I wanted was out of reach, but he came up with a smart, strategic approach that made it possible. Rigel's deep knowledge of the market and expertise really showed, and I felt confident in every decision because of his guidance. The entire process moved quickly, and the deal closed exceptionally fast—something I know wouldn’t have happened without Rigel's efficiency and strong communication. He was always responsive, clear, and kept me informed at every stage. On top of that, Rigel is genuinely friendly, easy to work with, and incredibly trustworthy. I always felt like he had my best interests at heart, which made the whole experience smooth and stress-free. If you’re looking for someone who is knowledgeable, patient, supportive, a great communicator, and truly dedicated to his clients, I highly recommend working with Rigel.
Laurie Pfohl worked tirelessly to market my house and it sold very quickly. She is knowledgeable and professional and was always available to answer amy questions. I highly recommend her.
Karen was more than a real estate agent, she's a real estate fairy godmother. She helped us find our dream home, albeit a fixer upper, but she saw the house's potential before we did. She and her team's market knowledge and strategic guidance helped us purchase our dream home in our dream location, AND renovate it IN OUR TIMELINE. Who knows of a successful renovation that stayed within the projected timeline?! She communicated with her contractors frequently (there were many), and ensured that our expectations were met. If there was any concern, she hopped on the phone to solve it quickly. She truly went above and beyond for us as if we were family. I will literally refer her to anyone thats even remotely interested in buying a home :)
I worked with Sebastien for roughly 6-7 weeks on my first home purchase. It was quite the experience. He and his team were responsive and patient as I and my family spent time combing through the choices he curated for me. We were able to meet up with him and spent 2 days visiting 7-8 to different properties to get a feel of what worked for me and what was undesirable. Once we had settled on a property, he got me connected with an escrow agent while I spent the next 4-5 weeks haggling with my bank/lender. He advocated for me during a period of stagnancy with the bank/lender. And he was always available for questions that I and my parents had during the whole process. Would recommend him and his staff. Very great, calm, and professional. Absolutely enjoyed working with him.

Every verified review on RateMyAgent is linked to a specific property transaction, ensuring that the feedback comes from real buyers and sellers. This also allows you to view key property details - such as location and number of bedrooms - so you can find reviews relevant to your own real estate journey. With our verification process, you can trust that the experiences shared are real, reliable, and helpful.
Integrity is at the core of what we do. We conduct rigorous daily integrity checks on all reviews, using multi-stage verification to analyze submission data and behavioral patterns for potential anomalies. Suspicious reviews may be rejected outright or escalated for further scrutiny by our internal team.
Transparency and fairness are core to how RateMyAgent works. While it’s sometimes assumed that only positive reviews appear on our platform, that’s not the case.
Only clients involved in an actual transaction with an agent can leave a review. This helps ensure authenticity and prevents fake or anonymous feedback. Agent's have no control over what’s written - every review, whether positive or critical, is published and remains visible.
Through verified reviews and price satisfaction insights, we highlight top-performing agents who consistently exceed client expectations.
