The Board

Klem Bio Pic1Larry Klementowski, President

Larry (known as “Klem” around the park) was born and raised in cold & snowy Buffalo, NY; that’s one reason he lives in Southern California!  Klem was an Air Force pilot, mostly flying the C-9A Nightingale, an Aeromedical Evacuation airplane.  He flew hospital patients around most of the Americas.  Don’t get him started on flying stories!  In 1982, Klem left the Air Force, moved to Placentia,  and started a new company, which designs and builds various military and civilian aerospace video products.  Klem loves the outdoors, including geocaching, hiking and mountain biking; he passed that love onto two grown daughters.  He has been volunteering at the CHSP Discovery Center for several years, and can be found behind the Discovery Center desk on many Sunday mornings.

Mary Glaser, Board member

Mary was born and raised in Southern California and has lived near Chino Hills State Park (CHSP) for over 30 years. She loves traveling, hiking and photography and has hiked on all 7 continents in places such as Antarctica (her favorite), Patagonia, Peru. Ecuador, Greenland, Iceland, Norway, Switzerland, Scotland, Mongolia, Nepal, New Zealand, and Kenya. Mary hikes often in the local mountains and nearly every week in CHSP. Mary has the dubious distinction of being helicoptered out of CHSP after breaking her leg while hiking. Her recommendation is to pay attention, even if the trail is flat and easy!
