Dave Mungenast, Sr. was born in St. Louis, Missouri on October 1st, 1934. His south St. Louis upbringing was influenced by motorcycles at an early age, and became his first opportunity for his own business in 1965. His motorcycle business opened the door for car dealerships and, somewhere along the way, he developed a friendship with Stan Barrett, a Hollywood stuntman and director. This friendship lured Dave away from his businesses to work on movies such as "Airport '77", "Hooper", "Cannonball Run" and "Harry and Son". Dave has been married to Barbara (McAboy) Mungenast, since 1959. He has three boys, David, Raymond, and Kurt.
