About Us

Meet the Castle Real Estate Group.

We have been helping people in Arizona find the place where they feel they belong for over 20 years. We are parents, we are business professionals, and we have our hearts invested in our beautiful state.

Community Partnerships

We value diversity and inclusion, having several family members that are part of the LGBTQ community. We proudly support ONE Community and the sincere work they are doing to help Arizona become a more inclusive state.  

As a locally owned and operated business, we know that when folks make Arizona the place they call home, they take pride in their neighborhood, their schools and their local economy. We are Local First Arizona members. 

Steve Castle

Associate Broker

I believe that at its core Real Estate is a people business. I have been incredibly blessed over the past 20+ years to help hundreds of incredible people achieve their Real Estate goals. Whether buying, selling or investing each and every deal has a unique set of circumstances and my commitment is to understand them and help my clients get the results they are looking for in the time they need. I do this by listening, understanding and then working together with my clients to create a game plan that’s right for them and then keeping them updated as we are executing that plan. When I am not working I love spending time with my family, reading and working out. Michal and I have been married for over 20 years and have two amazing daughters.

Giving back to the community is something myself and the team are committed to and is a hallmark of who we are and what we stand for. We support a variety of organizations both financially as well as with Volunteer hours. In 2018 my wife Michal and I founded ” Castle Real Estate Academy” a paid internship program designed to support youth at risk including those aging out of the foster care system by teaching them sales, leadership and entrepreneurship and giving them exposure to the many career opportunities in the Real Estate Field.

Originally from upstate New York, I started my real estate career in Tucson, AZ in 2015. I began working for a top producing team as their Marketing Director and Listing Manager helping them sell over 100 homes before pursuing my role as an agent in Phoenix. My passion for helping people is what motivates me most, both inside and outside of my career and keeps me striving for the greatest level of client service throughout the entire buying and/or selling process.
