Half a Century of Service:

Mainstreet REALTORS® Reach 50-Year Milestone

Mainstreet member Charles Castelo, Coldwell Banker Realty, one of the 50-Year honorees.


Fifty years. Half a century of serving clients, building committees and shaping the story of real estate across Chicagoland. This milestone is more than just a number. It represents perseverance, adaptability and a genuine love for helping people find their place in the world.


Think back to 1975, Interest rates were over 9%, listings were printed in binders and the only way to share a photo of a home was to hand someone a stack of glossy prints. Contracts were handwritten, negotiations took place face-to-face and business was built through phone calls, postcards and word of mouth.

Mainstreet member Sharon Kubasak, Baird & Warner, and Designated Managing Broker Andrew Croegaert, Baird & Warner.

Over the decades, everything changed. Fax machines gave way to email. Paper files turned into digital folders. Virtual tours replaced Sunday open houses and buyers began searching online before ever calling an agent. The world moved faster, and REALTORS® adapted with it. Yet through all the change, one thing stayed the same: the relationships.


To thrive in this business for 50 years takes more than skill. It takes heart. It means showing up for clients through every market swing, celebrating their wins and helping them start new chapters in their lives. It means being a trusted voice in the community and a steady guide when things get uncertain.


Our 50-year members have seen every high and low. They have mentored new agents, built lifelong friendships and left lasting marks on the neighborhoods they serve. They have witnessed the evolution of the REALTOR® brand, the rise of technology and the continued importance of professionalism and ethics in every transaction.




Today, Mainstreet REALTORS® proudly recognizes these remarkable individuals who have reached the 50-year milestone in 2025. Their careers remind us that success in real estate is not about chasing the next deal, but about committing to a life of service, learning and connections.

Mainstreet HQ, Downers Grove – Mainstreet is dedicated to making things easy for our members. After reviewing member feedback, we have made several improvements to the Forms and Contracts library to simplify and streamline your access. There are three different updates: 1. Log in to MyMainstreet and look for the green Forms and Contracts Icon, located in my tools across the top of the page. 2. Secondly, on the left side of the member portal, the purple vertical column of clickable resources says, “member resources.” Once here, look for the “forms” tab listed along the top of the dropdown menu choices. 3. Lastly, if you know which form you are looking for, instead of using member resources, navigate to the member portal page and in the same purple vertical column, look for “forms and documents.” Here you can search for the form you need by keyword. The above video details these changes, step by step. Click play to watch our tutorial video, brought to you by the Professional Standards staff at Mainstreet REALTORS®.

Mainstreet REALTORS® was honored to be a proud sponsor of Polonia Impact Day in Springfield on April 29 —an impactful day dedicated to celebrating and elevating the voice of the Polish American community across Illinois. We are especially proud that our 2025–2026 President, Kinga Korpacz, attended this important event as the first Polish President in Mainstreet’s history . Her presence reflects not only a personal milestone but also the growing diversity, leadership and cultural representation within our organization and the real estate industry as a whole. Polonia Impact Day brought together leaders, advocates and community members to engage directly with legislators, celebrate heritage and strengthen relationships that shape the future of our communities. The event featured special proclamations recognizing the contributions of Polish Americans, including efforts led by Senator Robert Martwick and presentations by Senate President Don Harmon, alongside support from Omar Aquino and Laura Murphy. Treasurer Michael Frerichs and his team also welcomed all participants to the Capitol, helping create a memorable and meaningful experience for all in attendance. Events like Polonia Impact Day highlight the importance of advocacy, cultural pride and community engagement—values that strongly align with Mainstreet REALTORS®’ mission. As REALTORS®, we know that building strong communities goes beyond real estate—it means showing up, supporting one another and having a voice in the decisions that impact housing and homeownership. We are proud to stand alongside the Polish American community and look forward to continuing to support initiatives that bring people together and make a lasting impact.

Mainstreet HQ, Downers Grove – Mainstreet’s Economic Outlook 2026 presented forecasts for the U.S. economy and possible Illinois housing market trends. That was in January. Halfway through the year, you need an update. Mainstreet has the data call you will want to hear for the second half of 2026. Listen in as NAR Chief Economist Dr. Lawrence Yun provides insights and advice about the back half of 2026. The Mid-Year Economic Update is a Mainstreet webinar focused on economic signals for the second part of 2026. Here is what Illinois voters think about the economy: - 81% Say Housing in Illinois is Unaffordable; - 65% Support Allowing Modest Duplexes on Larger Residential Lots; - 59% Bipartisan Support for Housing Affordability as a Top Priority; - 33% Have Had to Cut Back on Daily Essentials to Afford Housing. Using the information above, it is fair to say affordable housing and inventory are hot button issues in the world of economic headlines and topics. Specifically in Illinois where the supply crisis is squeezing middle class families out of the market altogether. For example, according to Illinois REALTORS® research, “Illinois would need to TRIPLE new home construction for 5 years in a row just to meet the current demand.” – Excerpt from IR Unlocking Our Housing Plan 2026. Now hear what Dr. Lawrence Yun has to say! The update coming from Dr. Yun, Chief Economist at NAR will provide critical information about what buyers and sellers have been doing so far in 2026. Knowing what your clients want based on buyer and seller behaviors gives you an advantage over other agents who are a day late and a dollar short. A one-hour webinar is a small price to pay for an increase in Q3 and Q4 sales volume. Click here to register today for the Mid-Year Economic Update.
