Captain Tim Sparks, U.S. Navy (Ret)

Tim has been on and around boats of all types and the waterfront his entire life. After a rewarding career in the United States Navy as a Surface Warfare Officer and warship captain, Tim decided to combine his passion for boating, teaching, and coaching with the experience and professional skills he learned through his naval service to create a top-notch marine services company for the Clarks Hill / Thurmond Lake and Greater Augusta boating community. Tim is a U.S. Coast Guard licensed captain, a certified U.S. Powerboating instructor, a towboat captain, and a lifelong sailor.
