My family and I moved to St. Louis in 2011 and joined Rockwood Swim Club for the 2017-2018 season. When I’m not coaching or working in marketing, I enjoy conversations with my girls, Zoe and Izy, running, cooking, and spending time with my dog, Penelope.

LAURA PASKOFF, Assistant Group Coach ([email protected])
Hello! My name is Laura Paskoff. I am assisting with several groups this year. I am a veteran of Rockwood Swim Club. I joined the team with Swim America at the age of 5 and eventually earned my way to our National Group at the start of my freshman year of high school at Lafayette. I represented both Lafayette and Rockwood in high school, training and competing year-round all four years of high school. Upon high school graduation I went off to swim at Illinois State University (Go Redbirds!), an NCAA Division I program in Normal, Illinois where I studied elementary education. In my four years at ISU, I was grateful to earn my degree and successfully complete four years as a student-athlete.

Since graduation, I have found my way back home to St. Louis and with Rockwood. I work full time as a middle school language arts teacher in the Hazelwood School District. My heart is with the kiddos and I am so passionate about these two teaching roles. When I am not wearing my teacher/coach hat, I enjoy being active, reading, and watching baseball (Go Cardinals!).
