I know of 2 brunswick centers that use Pro Trainer, Brunswick Zone in Woodridge (75th & rt355) or Brunswick Zone in Deer Park (rt12 in Lake Zurich). I believe that Michelle Mullins, former womens tour bowler, teaches at Woodridge and Mark London, regional bowler, at Deer Park. Otherwise a trip to Greendale, WI to work on the CATS system there is also possible. Good Luck.
