Dean LaMar Allen was born in Las Vegas in 1927 on the historic Kyle Ranch, where he grew up with his parents, sister and two brothers. Mr. Allen attended the Fifth Street Grammar School, Las Vegas High School, and then graduated from Brigham Young University with a major in Zoology. He attained a Masters Degree in Education and received National Science Foundation Scholarships, and afterwards was a U.S. Navy Veteran of World War II. Mr. Allen began teaching in 1952 at Jefferson Elementary. From there he went to J.D. Smith Junior High, Crestwood Elementary, and John C. Fremont Junior High School.
Going the extra mile was Mr. Allen's belief, and he did this with every aspect of his teaching career. He coordinated science fairs, sponsored science clubs, astronomy research, and Saturday field trips to Mt. Charleston, Red Rock, and Lake Mead. He initiated the "hands on" lab programs at Fremont Junior High. He believed that learning was about "doing" and experiencing it yourself. He wanted his students to experience the magic of science, not just read about it from a text book. It was very important for Mr. Allen to be there for any student who needed extra help.
