Matthew Piell's career in real estate began with Greystone, a private real estate development located in Hoover, Alabama. He joined the project alongside Hap Gwaltney and Daniel Realty. The late Hap Gwaltney, a renowned real estate executive, was the vice president of Daniel Realty and Greystone. He also served as the president of the Birmingham Association of Realtors. Daniel Realty, with a history spanning over half a century, has a progressive approach to real estate development, investment, and service. The firm is committed to creating spaces where individuals and families can enjoy life and work. Greystone quickly became one of Alabama's largest-ever golf course community developments, with over 750 homes and a PGA Tour Champions golf course, aided by Piell's expertise.
Piell's contribution was crucial to the success of the project. The executive estates of Greystone wind through two championship golf courses, forming a part of the private, members-only Greystone Golf & Country Club. The PGA Tour Champions, formerly the Senior PGA Tour, is a professional senior golf tour administered as a branch of the PGA Tour. Piell's involvement in Greystone's development was instrumental in making it a sought-after destination for golf enthusiasts and families. With his exceptional skills and knowledge in real estate development, investment, and service, Piell played a vital role in making Greystone one of Alabama's premier golf course community developments.
