About Coleen

The foundation of my business is TRUST, HONESTY & INTEGRITY to my clients. I want you to know how the market is changing and how it will affect your investment. You may not always like what I say. I am frank but professional. I work as a team with my clients in order to achieve the best positive results for them. Both financially and emotionally my clients are invested in making their real estate vision a reality and I am invested with them every step of the way.

With 22 years in real estate, I’ve built my business on experience, strategy, and a genuine love for helping people move into their next chapter.

Real estate is more than contracts and closing dates — it’s emotional, personal, and often life-changing. I don’t take that lightly. My clients trust me because I bring seasoned expertise, steady guidance, and strong negotiation skills to every transaction. I know how to anticipate challenges before they happen and navigate even the most complex situations with confidence.

One of my greatest strengths is my background in marketing and design. I understand how to position a home to stand out in today’s market. From strategic pricing and professional presentation to staging insight and high-impact marketing, I know how to make homes shine and attract serious buyers.

What I love most? The relationships. Many of my clients come back years later when it’s time to make their next move — and that trust means everything to me.

After 22 years, I still wake up excited to do this work. Helping people buy and sell homes isn’t just my career — it’s my passion.

During those moments when I’m not working, my husband and I are getting use to being empty nesters ourselves now. That has been a life change since. Our triplets all graduated from college in 2022! I now have a son living in California, my other son is in Ohio, and thankfully my daughter is still close by in Illnois. This alone was a huge endeavor but we enjoyed every minute of it. Extracurricular activities, social events, and family time keep us laughing and busy always. I am sure you can relate to this in one form or another.

So enough about me. I want to learn about you. I want to help you move forward where ever that may be. I want to help.
