Hi, my name is Rena Reiser and I'm the owner of Bigger Fish Books advisory bookkeeping service in Hill City, South Dakota, serving Rapid City, the Black Hills and clients across the country. I allow business owners to grow their business with confidence in their numbers.

​

I have a passion for helping small and medium-sized businesses succeed! I previously owned a large publishing company, promoting these types of businesses to a highly-targeted audience. Each day, I put my accounting and bookkeeping skills to work, while realizing that business owners run the risk of losing focus on the bigger picture when tasked with bookkeeping. I took that commitment to help them succeed and became an advisory bookkeeper and Certified QuickBooks ProAdvisor. 

​

I was born and raised in New Mexico, and relocated to South Dakota in 2024. My tendency to make lists and categorize items shows up in my leisure activities as well - especially marking locations off our bucket list as my husband and I travel in our RV.
