W. Allen Costellow | President & Co-Founder
Knowledgeable, respected and committed to making a difference in the lives of our representatives and their clients.
Allen Costellow, is the president and co-founder of Cornerstone. Cornerstone was founded as a subsidiary of Guarantee Trust Life Insurance Company (GTL) in 1995. The initial formation came about as a result of a long professional relationship between Co-Founders Allen and GTL CEO and President R.S. Holson III. They shared a common dream to build an organization that could offer the best products, the best trained representatives, and a unique opportunity for growth that did not currently exist in the industry. In 1995 a strategic initiative was begun by the two and Cornerstone was founded.

He holds a series 65, 63 and 7 registration as well as Life, Health, Long Term Care, Property and Casualty licenses in multiple states. His passion is helping clients and representatives to “Secure their Future” both financially and personally by offering sound financial advice to clients, and providing opportunities for growth and development to those who work with him.
