Meet Our Team


William “Bill” Barnes, President

Board Member since 2012

Bill brings so much more to Houston Ground Angels than his exceptional experience and business sense
to the office of President.  He also brings his passion to serve, a sincere caring for people, and common sense. Bill is one of our Arch Angels, a title given to those volunteers who have completed an exceptional number of Missions with Houston Ground Angels.

Bill is a native Texan, and has lived in Houston for 55 years.  He retired from the University of Houston Political Science faculty in 2010. Along with his many talents and skills, he is also a Licensed Private Investigator. Bill has a long history of involvement in non-profit  organizations, such as Past President, Westbury Homeowners Association, Past President, Rotary Club of Copperfield, Past President, and Harris County MUD #186. He also is, or has been, been associated with Taping for the Blind, Bear Creek Food Bank, Volunteer Houston and Vietnam Veterans of America.



Anthony “Tony” Castiglie

Vice President and Treasurer
Board Member since 2011

HGA is thrilled Tony has agreed to join the Board of Directors. He comes to HGA with a wide-range of executive management and professional business experience. He has worked for some of the top companies in the oil and gas and banking industries. Plus, he has the business experience of running his own successful company, which in many ways parallels running a non-profit such as HGA. Tony has been the Treasurer of the Houston Ground Angels since 2006 and so he is well versed in the details of our organization, including the financials. He also led the project team in designing our new logo. Tony has also continued to provide his leadership skills in many capacities within HGA and has attended all board meetings since 2006 where he has provided solid business advice.  Tony was elected to the Board of Directors in 2011. He is a native of Brooklyn, NY and has degrees from Milwaukee Schoolof Engineering and Louisiana Tech. Tony and his wife of 44 years, Sheila, have called Houston home since 1969. They are members of St. John Vianney Catholic Church.
