Marlene's Reviews
2/3/26Tony Zobott
I’ve gotten to know Marlene Castagna very well through our weekly Fox Valley networking group, Business Before Breakfast. While I haven't worked with her on a personal transaction yet, I can attest to her incredible discipline and work ethic. I know for a fact that she makes herself available at all hours of the day and night because she never wants a client to miss out on a deal. She is the type of professional who puts her clients' interests first every single time.
What really stands out is her attention to detail—her listings are consistently more thorough than others I’ve seen. She is incredibly humble and doesn't brag, but the testimonials I hear weekly from others in our group who do work with her regularly are always glowing. Her energy is amazing, and she is a natural problem-solver who does whatever it takes to get a deal to the finish line.

I have absolutely loved working with Marlene! She is exceptionally knowledgeable about the industry and market trends, and consistently goes above and beyond for her clients. She made the entire home buying process easy and enjoyable, and I would highly recommend her to anyone looking to buy or sell. If you want a moving experience, you definitely need to call Marlene!
