dr. sam botta

In the fall of 1975, Sam Botta began his freshman year of college at Old Dominion University. Although Sam initially thought he was attending ODU to play basketball, a senior named Fred Showers witnessed to Sam at a party in his dorm cafeteria, and then introduced him to Pastor Joe Mullen, who led Sam to accept Jesus Christ as Lord and Savior. Sam soon realized that God had ordained for him to be there not to play basketball, but to place his faith, trust, and life in the everlasting arms of Jesus. After incurring a season-ending injury, Sam left ODU, and completed his bachelor’s degree in health and physical education at The King’s College in New York. Dr. Botta began his professional educational career in 1983 serving as a physical education teacher and basketball coach, leading his teams to numerous tournaments and championships. In 1997, he was named the top high school basketball coach in New Jersey, and in 2010, he was inducted into the Egg Harbor Township Sports Hall of Fame. He acquired Master of Education and Doctor of Education degrees from Regent University in Virginia Beach, where he was awarded the first-ever George W. Selig Fellowship Award, as well as the Distinguished Scholar Award. Dr. Botta went on to serve as principal and head of school at several Christian schools and then as the Director of Athletics and head men’s basketball coach at Regent University before joining CCA as our Head of School. He and his wife Lynda have four adult sons: Danny, Scott, Brett, and Jeff.

At CCA, we are committed to coming alongside families in helping our students explore and discover the unique gifts, passions, and dreams that God has placed deep within them.

cassandra madsen

Cassandra Madsen was raised Catholic, but always felt a hole in her life and heart. She craved a personal relationship with Christ and started to actively seek Him early in her military career. After she and her husband were married, the Lord led them to Cornerstone Chapel. Mrs. Madsen knew it was where God wanted them to raise their family and build a community.

Mrs. Madsen has over 20 years of experience in the US Navy, Federal Government, and private sector. She served four Presidential Administrations, most recently as the Chief Operations Officer under the Executive Office of the President. As a military veteran, Mrs. Madsen accumulated over 1,000 flight hours as a Naval Flight Officer and Mission Commander on P-3 Orion aircraft, including missions in support of Operations Iraqi and Enduring Freedom and missions in Europe, Africa, and Central America. Mrs. Madsen holds a master’s degree in leadership from Georgetown University and a Bachelor of Science from the State University of New York Maritime College. She lives in northern Virginia with her husband and five children.

bill oblas

Although Bill Oblas went to church every Sunday from childhood, he did not accept Jesus as his personal Savior until he was 21. His then-fiancé, Sally, had a burden for Bill to know Christ (she was saved several months earlier), and she led Bill to the Lord. Bill and Sally have been married since 1973.

Mr. Oblas’ educational career spans over 40 years, including 10 years as the principal of Loudoun County High School. He earned his bachelor’s degree in education from Bloomsburg University in 1973 and acquired a master’s degree from Virginia Tech in 1976. While Mr. Oblas retired from education in 2014, he came out of retirement to support Cornerstone Christian Academy as we make critical operational decisions. His expertise in education and familiarity with the nuances of Loudoun County make Mr. Oblas an invaluable part of the CCA team. He and Sally reside in northern Virginia, and are blessed to know that their three children, their children’s spouses, and eight grandchildren all walk with Jesus.

executive assistant to dr. botta

kimberly kohr

Originally from Long Island, New York, Kim Kohr grew up in the Catholic church, but did not fully surrender her life to Jesus until she had children of her own. She and her family began attending Cornerstone Chapel, and although she was baptized as an infant, she made the decision to publicly profess that Jesus is Lord of her life and decided to be baptized again as an adult.

Before joining the Cornerstone Christian Academy team, Kim spent her career as a civil engineer working for a large, heavy civil contractor on major public infrastructure construction projects in New York City, Baltimore, and Washington, D.C. She loves spending time with her family going on adventures, exercising, working in the yard and anything to do with home renovation, decorating and real estate. She and her husband have been married for 10 years and have four beautiful kids.
