Kendra Kalvin:
Head Coach


[email protected]

Hi, everyone! My name is Kendra Kalvin and I am very excited to begin my ninth year coaching with the Stingrays. This summer I will be returning to the Stingrays as the Head Coach for my fifth summer. This team means a lot to me and has always been a huge part of my life!

To share a little about myself, I am in my second year of teaching after having graduated from UW-Eau Claire in May 2018. I am teaching first grade and absolutely loving it! Outside of school I enjoy reading and spending time with friends and family at our cabin.

I am so excited that we are able to swim this year! Please feel free to email, call or meet with me as I am more than happy to answer any questions, comments or concerns.


Forrest Peterson: Technical Coach

Hello, I’m Forrest Peterson, a Senior at Middleton High School, and I am excited to be a part of this year’s Cross Plains Stingrays coaching team! I have been on Stingrays for eleven years and have loved every year more than the last. I have no doubt this year will be another great year! The past 3 years as a helper coach I have learned so much, and I am looking forward to using my experience as a technical coach this season. I can’t wait to see all the new faces as well as the many returning ones! I know we will have an amazing team this year! 

In addition to being a helper coach last year, I also swam on the Middleton high school state team and through it have learned more about coaching and set planning. Most of my eleven years as a USA Swimming club swimmer I have qualified for State, and last year I had the chance to swim at a junior national meet. Other activities I enjoy include writing music, hiking, camping, solving puzzles and reading. 

I hope that I will be able to use all that I have learned over my many years of swimming to help make our team stronger all while maintaining the fun atmosphere our team is known for. I have always loved the fun days, and I hope to go all out this year! I am ready for another amazing season! Let’s go Stingrays! 

Halley Johnson: Assistant Coach, 15-18 Age Group Coach

[email protected]

Hello Stingrays! I am glad to be back for my third summer, as the Stingrays 15-18 age group coach! Coaching for the Stingrays has been an honor and I feel very grateful to have the opportunity to continue to instill the values the Stingrays have always represented.

Over the last decade I have spent my time coaching both College and High School teams as well as club and rec swimmers. I have enjoyed my time with all the teams or individuals I have coached, they have all taught me valuable lessons for life. What is so incredibly special about this team is the family bond that has been built within a great community. I have been a Stingray since I was 3, spending every summer deep in the Stingray way of life. Coming back, a decade later, to feel like I was coming home, like no time had passed, there’s no better feeling. So, needless to say, there is no place I would rather be at 5:30 in the morning then at the pool, ready to convince your teenager that getting into a lukewarm pool is way better than their warm cozy bed. 

I am here for your swimmers, to make this their best experience. I believe communication is key, so please let me know if you have any questions, comments or concerns. Please do not hesitate to reach out to me via email, phone or with a heads up, stopping by after a practice. I am looking forward to a great summer, full of hard-work, dedication & fun! Go Sting!

Ian Bohachek: Helper Coach 11 -12

Hi, I’m Ian Bohachek and I am excited to be returning as an 11-12 helper coach with Stingrays this year. I joined Stingrays when I was 6, and now I am 17, so this is my 12th season with our awesome team! I am a junior at MHS, and I have been on the cross country and track teams for 3 years in addition to the high school swim team. When I am not swimming, running or doing homework, you might find me playing the cello for the school orchestra, or solving problems with Future Problem Solvers. 

I worked at the Cross Plains pool the last two summers, and I will be working there again this year. Working at the pool gave me the opportunity to help with swim lessons, and it was rewarding to help swimmers become more comfortable in the water. I look forward to helping the 11-12s grow and develop their swimming as well as continuing to experience the fun and friendships that swimming summers with Stingrays can bring.

[email protected]

Hi Stingrays! My name is Emma Neumann, and I am thrilled to be the 9-10 coach this season. This will be my fourth year as a coach for the 9-10s. I was a swimmer for the Stingrays for 13 years and swam on the Middleton High School team for four years. I am currently an undergraduate at the University of Wisconsin-Madison studying biomedical engineering, and I work for a biotechnology lab primarily with genetics and robotics. 

The 9-10 age group is such an exciting time for any swimmer. It is a big jump from 8 & Unders to 9-10s, but that just means there is even more room for improvement and growth. That is why I love the 9-10 age group so much and am so eager for another amazing season. My goal is that all my swimmers learn what it means to work hard and be dedicated while also having fun and forming a lifelong community. I am very excited to see all of the returning swimmers and all those that are new to the team, and I cannot wait to share my love for swimming and the Cross Plains Stingrays.
