Owner Sean Hanley has spent his entire career in the golf course industry. After working through college at UVM as a member of a golf course maintenance crew in Vermont, he went to work on the construction of golf courses for the renowned golf course architect Robert Trent Jones Jr.

Starting as a labor crew foreman, Sean moved up the ranks to finish shaper, shaper, and eventually site superintendent, overseeing all the work and subcontractors involved in the process of building new golf courses.


He spent ten years building new courses for this world class organization. This experience has afforded him the opportunity to learn from some of the best architects and shapers in the industry, as well as travel to and work on some of the most prestigious courses around the world.


Having settled in Acton, MA with his wife Christine and two children, Sean has spent years serving the renovation and restoration needs of golf courses in the New England area and beyond, forming On-Course Golf.
