Castle Hill Investments Team

Robert Grunnah, Jr.

Broker/Owner

Robert feels extremely lucky to have built a successful company out of his real estate passion. Robert has consistently won top producer awards and sold over $150M of real estate since entering the business in 2004. He owns income property throughout Central Austin, and has flipped over 100 houses. This experience translates to extremely effective client representation, particularly amongst rental property, duplexes, and seller representation in his "adopted" 78704 South Austin neighborhood. A Dallas native (and student of St. Mark's School of Texas), Robert moved to Austin in 1992. He received his MBA in Real Estate Finance and Entrepreneurship from the University of Texas at Austin in 2004, and his BBA in Finance from the University of Texas at Austin in 1996.

Bryan Kosarek

Investment Sales

Bryan has been fascinated with real estate since he was a youngster. His career has so far explored many areas within the industry including architecture, construction management, flipping, and property management. Bryan was the first employee of Castle Hill and has been proud to grow with the business, learning the nuances of each neighborhood and industry cycle. Bryan received a BA from the University of Texas at San Antonio. As a native of Chicago, Bryan appreciates the “small town” feel that Austin has to offer. Yet he can also see the vision of Austin’s vibrant future. He has made it a goal to purchase one investment property per year personally, and is on track to achieve this goal. His long term focused, consistent approach is the best way to build wealth in real estate. Bryan follows two rules in life and real estate: “If it is too good to be true, then it probably is”, and “There is no elevator to success - you have to take the stairs." Bryan lives in East Austin, and additionally favors investing in technology job locales we call “The Technology Corridor”.

Heather Kight

Investment Sales

Since buying her first Austin property in 1985 and surviving the real estate bust, Heather’s real estate purchases have only gone up from there. After a career teaching at one of the nation’s top high schools, Heather went on to work as the National Senior Marketing Manager for a leading educational publisher, landing at Keller Williams International where she spearheaded the corporate university’s distance learning program. She obtained her real estate license, her Relocation Specialist designation and her EcoBroker® certification. She was recruited to Castle Hill Investments as a Buyer’s Representative due to her high volume record. Her experience in single family home sales and her marketing expertise make her the perfect person to serve as our Instant Equity Coordinator – she gets results through high volume traffic and quick sales on IE listings. If you are buying or selling a property in Austin, this Austin native’s familiarity with schools, neighborhoods and property value is beyond compare.

Adrienne Laosa

Listing Coordinator

Born and raised in the Lone Star state and the youngest of five children, Adrienne brings a motivated, friendly, and intelligent focus to the Castle Hill team. After graduating from St. Michael’s Academy in Westlake and attending Baylor University for 2 years, she found her way back home to Austin where her high-achieving personal career goals continue to flourish. Adrienne loves entertaining friends and co-workers, listening to any type of live music around, and loves fishing, dogs and camping in West Texas.

Daniel Wyler

Office Manager

A transplant from Folsom, CA, Daniel moved to Austin in November 2007. In the process of transferring to the University of Texas to study business, Daniel is working on his real estate license, and looks forward to the day when he can work with investors. In the meantime, Daniel helps us with the vital tasks that keep real estate business humming – placing signs, managing office activities, and helping with phone duty. When not at work, Daniel enjoys running, tennis, spending time on the lake, and relaxing at one of Austin’s great lakes.
