In 1962, Elizabeth "Betty" Krolak moved from the Midwest to Las Vegas with her husband and six children. She attended a real estate class her husband had enrolled in but was unable to complete. Betty passed the test and became a licensed Nevada real estate broker in October, 1963. She initially went to work for Pyramid Realty, and in 1964, she opened her own office, Clark County Realty. She was appointed by Governor Michael O'Callahan to the State of Nevada's Real Estate Commission, making her the first woman to serve on the Commission. Betty also volunteered with the Salvation Army and was instrumental in establishing their Angel Tree project in southern Nevada, which provides Christmas presents to children who would not otherwise receive them.
