Bookkeeping About Us

Our bookkeeping service is provided by Jenny Slusser. Jenny is a bookkeeper who works with veterinary practice managers to alleviate the stresses of the day to day financial drudgery. She is an efficient multi-tasker with a long history of experience with project management. She also knows that her experience with budget development will allow her to work closely with your managers to run the practice and come up with fiscally sound strategies for growth.

Jenny has over 30 years of experience in the veterinary field, including 20 years of service at Wheat Ridge Animal Hospital as the Financial Manager.  She will bring your clinic a robust knowledge of a variety of veterinary hospital information systems, financial systems, as well as implementation experience with ADP payroll, HRIS, and time clock software systems.

Jenny resides in Littleton, Colorado with her husband Hal, daughter Amber and two dogs, Lexi (Boxer) and Bella (Jack Russell).  She enjoys horseback riding, hiking and reading.

Jenny Slusser is an accounting whiz!  She’s very detail oriented and makes sure the accounting piece of operating a veterinary clinic is done well.  It freed me up to work with staff and marketing which in turn helped our business increase by 19% in a year.  We’ve now added a 4 th doctor and our hospital is in great shape for growth.  Because our P and Ls were correct this gave us accurate information to make business decisions.  I can’t say enough good things about what Jenny helped us do.  She’s also a great trainer and, because of this, I have a better grasp of hospital finances that will help me do a better job going forward.
