Vickie Kempinger
Director of Operations - Legal
Vickie Kempinger has been around rental properties since she was seven years old. She credits her Dad and Aunt for getting her started at such a young age and is grateful she had the opportunity to learn the business hands-on — from painting and mowing lawns to helping with remodels and cleaning out units that were sometimes not so pretty. Those early lessons gave her a real-world understanding of what rental properties truly entail. As a bonus, she greatly enjoyed working alongside her Dad and Aunt for many years.
One month after graduating from the University of Wisconsin–Milwaukee, Vickie purchased her first duplex back in Oshkosh. While her degree and business ownership steered her primarily into Accounting roles, after joining Blue Frog in 2018, she gravitated toward the legal and compliance side of the business.
Vickie credits patience, and thick skin as essential while navigating through tenant evictions which makes up a significant part of her role at Blue Frog. She was charmed when a fellow co-worker coined her “The Evictinator.”
Vickie is especially proud of her children for recognizing the value of investing in real estate and now owning rental properties of their own.
