Leslie has over 20 years of active real estate brokering. She specializes in apartment complexes and 1031 tax deferred exchanges. She began her career in Long Beach, California and planned to retire after successfully investing in residential income producing properties.

Instead, Leslie and her husband, Broker Jim Clauson purchased Real Estate Training Institute on the Gulf Coast of Mississippi in 2011. She has written and published four Mississippi specific real estate exam textbooks, four variations of pre exam general information textbooks, and a book for the Tennessee exam. Leslie has had two 30-hour courses approved by ARELLO. In 2018, she connected the Myers-Briggs® theory of psychological types with her Continuing Education courses. Using her Myers Briggs® Practitioner License, she designed a certification series of real estate CE courses leading to the designation, “EXCEL Yourself” for real estate professionals.
