Before he became hooked on scuba diving Greg was in the marketing field as a copywriter in New York and Washington, DC. He and his wife Jennifer have a 5 year old son, Sam, who likes blowing bubbles in the tub and letting the hose run in the front yard for hours on end. Pure naturals in moving water, the Zajac men have more than once started to wash the car before they realized the windows weren't rolled up.

Recently a baby sister arrived for Sam. Mallory enjoys water. This is evident by the way she crawls over to the dog’s water bowl and dumps it out on the kitchen floor every chance she gets.

An officer with the Lake Monticello Water Rescue Team Greg has spent numerous hours in very dark, very cold water looking for lost objects in the mud. He is trained as an NFPA recognized Swift Water Rescue Technician, Emergency Response Dive International (ERDI) Public Safety Diver, LifeGuard Systems Ice Awareness Diver, DAN O2 and Hazardous Marine Life Instructor, and an Emergency Medical Technician (NREMT-Intermediate).

A PADI instructor with a Master Scuba Diver Trainer rating, instructor level certified in deep, navigation, search and recovery, wreck, dry suit, enriched air, and night diving, he is also experienced in full face mask and underwater evidence recovery.

Greg is currently a teaching member of Piedmont Water Response, helping local communities develop, train and maintain public safety water response teams. (www.piedmontwr.org). He is also working with Assistant Instructor, Marty DeReus, teaching the scuba program for Southern Virginia University in Buena Vista, Virginia
