Hi, I'm Nik Castilleja! I grew up in Pflugerville, TX, and now work with clients throughout Dallas, especially in the Uptown area. I graduated from Texas State University with a degree in Mass Communication and Advertising, and my background in real estate, spanning land sales to multifamily leasing, helped me sharpen my ability to guide people through big decisions with confidence and clarity.
My family is based in Austin and heavily involved in real estate, so helping others navigate important life choices comes naturally. I'm passionate about learning and teaching insurance strategies that help individuals and families prepare for the future. I also enjoy collecting books, coins, and baseball cards. Baseball has been a big part of my life, I was fortunate to play at the collegiate level.
I chose Mutual of Omaha for its legacy of trust. Let's build your financial foundation together, book your appointment today!
