Leading with Integrity, Experience, and Heart
At Realty ONE Group Cornerstone, we believe real estate is about more than just buying and selling homes—it’s about people, relationships, and creating opportunities. At the heart of our company is Julie Hesselmann, a seasoned real estate broker with a deep-rooted passion for helping clients and agents succeed.
Julie’s career began in the financial services industry, where she spent nearly three decades gaining extensive expertise in mortgage lending, investments, and financial planning. In 2016, she made the transition into real estate, bringing with her a wealth of industry knowledge and a service-first mindset.
Her drive and expertise led her to obtain her Missouri Broker's license in 2019 and her Kansas Broker's license in 2023. After years of working at another firm, she knew it was time to build something of her own—something that aligned with her vision for a client-focused, service-driven real estate experience.
In July 2024, Julie officially launched Realty ONE Group Cornerstone, with a clear goal:
✔ To create a supportive environment for agents where they have the tools, training, and mentorship needed to excel.
✔ To servce clients with honesty, expertise, and integrity, ensuring their real estate journey is as smooth and stress-free as possible.
✔ To build a compan culture that values relationships, recognizing that real estate is about more than just properties—it’s about people.
Under Julie’s leadership, Realty ONE Group Cornerstone will grow, attracting top-tier agents and making a meaningful impact in the St. Joseph area. Whether you’re an an agent looking for a brokerage that values your success or a client in need of a trusted advisor, Julie will be here to help.
