  • Harold Strom
  • Facilities Manager
  • Harold comes to the Ronald McDonald House after an almost forty-year career in the Horticulture industry. During that time, he has worked for nurseries located in Quincy and Apopka, Fl. and even San Pedro Sula, Honduras for a short while. He finally moved to Gainesville in the mid 80’s and shortly thereafter, he met his wonderful wife of over thirty years. They are the proud parents of one adult son. Harold has been fixing things his whole life. That started on the North Florida farm where he grew up and continued as he helped his five uncles who all had businesses related to the construction industry. Ronald McDonald House holds a special place in his heart because some of his own family were able to stay at a Ronald McDonald House to be close to their newborn son who spent several months in NICU. Harold enjoys fishing on the area’s lakes and rivers and traveling with his beautiful wife. He also loves to watch the Gators play ball.
