Allen Pools & Spas was founded in 1957 by Dan Allen Sr. who was working for the State of Vermont as a Registered Civil Engineer.  He was contacted about designing and building a swimming pool for the Girl Scout Camp at Tammarck Notch in Mendon, VT.  He agreed and built his first pool.  He was then contacted by a few more people that had purchased pool kits and hired him to install them.  Realizing the potential for a thriving business, he started selling and installing in-ground pools all over Rutland and Windsor counties.  Even after building thousands of swimming pools, Dan Allen Sr. never learned to swim a stroke.
