Coaches and Directors

JAWS Coaching Staff
Raymond Onisko Head Coach - Black / White groups
Hello –
My name is Ray Onisko, and I am extremely excited to be the new Head Coach for JAWS and the assistant aquatics director here at Jenison HS. My wife and I are originally from Michigan and are returning to Michigan after an exciting and incredibly positive 4 years in Greenwood IN, where, as the Head Coach for the Greenwood Gators and Greenwood HS, developed a tradition of fundamentally strong, extremely competitive and high achievement both in the pool and in the classroom.
I have been involved in competitive swimming for 44 years, 12 years as a swimmer (with the Macomb Marlins / Notre Dame HS in Harper Woods) and the past 32 years as a coach with both Club and HS Teams. I enjoy coaching /teaching all levels of swimming from the learn to swim beginner, senior development swimmers, high school swimmers as well as collegiate athletes. As a coach, I take immense pride in aiding swimmers to develop their potential which leads them to
continue their swimming careers as either successful collegiate swimmers or as young coaches, who are now imparting their knowledge onto swimmers of their own.
On deck, I believe the foundation of every successful swimmer begins with strong fundamentals coupled with age-appropriate training both in water (based on IM training) and dryland.  Proper mechanics lead to good swimmer health where all energy systems can be challenged in a creative way.  Swimming is challenging but there is always a way to have fun while working hard.  Out of the pool, I believe it is extremely important to conduct yourself in a manner which brings pride to your
team and your school. Always be respectful in your actions and accountable for all you do.
In Michigan, I have coached with Utica Shelby, Atlantis Swimming and Motor City as well as LiquidLightning. As an ASCA level 3 certified coach, I have had numerous Junior and Senior National Qualifiers, High School State Champions and All-Americans, as well as assisting in the development of Olympic Trial Qualifiers. I have served and assisted both the Michigan and Indiana LSC Board of Directors. I have been fortunate enough to serve as a delegate to the USA swimming convention.
Education is the key to the development of both swimmers and coaches. To that end, I am always exploring and speaking with many coaches around the country to see what they are doing, how itworks and how can I incorporate into what we do.
My wife Brianna, our two daughters and our two spoiled cats look forward to beginning our journey here in Jenison with JAWS!
I am always open to conversations, via phone, email or in person.
Please emaiI your questions to:  [email protected]
I look forward to seeing you at the pool!
Jennifer Coffey Coach

Jen is a sub for Black and White group and is currently coaching a Green Group! This will be her 18th year coaching JAWS! Jen, along with Caroline Clement, began the JAWS team in 2003, and she has enjoyed watching the team grow and progress over the years. She is very proud of the swimmers, parents, and coaches here at Jenison!

Jen swam and played water polo at Jenison HS from 1993-1997 under Coach “Scrips” and Coach Caroline. She was very active in USA swimming, but Forest Hills (RAYS) was one of the few local USA teams during the mid 90s so she drove across town daily to keep swimming. Coach Craig was one of the coaches at RAYS while Jen swam there! After HS she went on to swim and play water polo at The University of Michigan from 1997-2002 while earning her undergraduate degrees in psychology and sociology. From 2002-2003 she was a member of the USA National team for water polo and lived in California where she trained. 

She participated on the USA Jr. National Team on a trip to France, and the USA National Team on a trip to China during her swim career. She also participated in the 1996 and 2000 Olympic Team Trials for swimming. She was also fortunate to play water polo for Team USA at tournaments in Greece, the Netherlands, and Austrailia. In 2003, when she retired from swimming and water polo she headed back to Jenison where she began to substitute teach at Jenison, coach JV men’s water polo, and begin her Masters degree at Western Michigan University in counseling education. Fortunately the pool director job opened up at Jenison, and although she always thought she would be a school counselor the pool director position was just too perfect so she applied and the rest is history!

Jen is very busy (read: too busy :-)! She married her husband Landry in 2005, had Kylie in 2008, had Meric in 2011, earned her Masters degree in Educational Leadership in 2011, had Nylah in 2015, and currently helps coach, administrate, and plan for JAWS year round, coaches JH Co-ed Water Polo in the fall, coaches JH Girls' Swim and dive in the winter, all while being the pool director full time year-round. She was inducted into the Grand Rapids Sports Hall of Fame in 2009 for swimming and water polo. She was also inducted into the Jenison HS Hall of Fame in 2015. Jen says she surrounds herself with great people that make her job easier and so much fun. She loves Jenison, loves the pool, loves coaching,and loves swimming and water polo!

Caroline Clement Coach

I have been coaching competitive swimming since 1983 (age 17). During my career, I have acted as the Asst.Varsity Women's Swim Coach since 1990, Co-Head Varsity Men's Coach since 2011, and served as the Head JAWS Coach from 2002- 2014.  During my tenure as a coach, I have also assisted the junior high program, assisted the High School Men in the early 2000s, and started my age group career as an assistant in 1998, prior to heading the JAWS program.  I will continue with JAWS on part-time basis as an assistant coach.

My swim career started in Jenison with their age group program in 1973, and I swam for Jenison High School under Dan Scripsema (Scrips) from 1979 - 1982.  I competed for the University of Michigan during the 1983-1984 season.

My philosophy is that all swimmers should learn proper technique while coupled with training, as appropriate for the age.  The emphasis with novice swimmers should be learning technique and the rules of competition.  As the athlete gains experience, rigorous training is increased, while still emphasizing proper technique.  Of course, fun should always be implemented so that athletes want to remain in the sport.

This summer Coach Caroline will be working with members of the White and Black group during the afternoon Long Course Workouts.  She will also be assisting during the AM workouts as needed by the program.

Craig Westra Coach - White & Black Group

Craig is happy to return for his 25th? (I lost count) JAWS swimming season. Before coming to JAWS, Craig coached Jenison's Age-Group program back in the mid 1980s through early 1990s. From there he coached the newly formed Rapids Area YMCA Swimmers (RAYS) swim team in Forest Hills and was an assistant coach of its YMCA Long Course National Championship teams in  1993 and 1994. With USA Swimming being a large part of his life, Craig coached a Hudsonville satellite program with West Michigan Swimmers (WMS) for five seasons. He is recently completed his 8th season as assistant coach for Jenison's Women's Varsity Swim Team and is enjoying his time coaching Jenison Junior High's Girls and Boys Swim Teams..

Craig is a proud 1986 graduate of Jenison High School where he swam for 3 years on its varsity swim team. He attended Grand Valley State University, swimming one season and graduating with a degree in Group Social Studies and Elementary Education. He later returned to GVSU to earn his Masters Degree in Elementary Leadership. Craig is currently a fourth grade teacher at Bauerwood Elementary in Jenison. Craig has three children, all who have participated in Jenison's swimming, diving, and/or water polo programs. Craig enjoys watching young people reach their goals, swim fast, and become successful. Swimming is more than a sport, it's a lifelong skill filled with lifelong memories. Go JAWS!

Christine Wisniewski Coach - White Group

Hello, my name is Christine Wisniewski. I started coaching for JAWS in fall of 2018. I started swimming as an 8yr old for the Wyoming Wahoos during the summer seasons. We lived in Louisiana and would come home to visit family during the summer months. My family moved back to Michigan when I was 12 and I started swimming for the Hudsonville Eagles and continued through my senior year of high school. I was fortunate to start high school right after Hudsonville started their first water polo club, and was a part of the very first varsity program. During my high school years I also coached for the age group swim program year round.

I graduated high school in 1999 and continued my education at Michigan State University. While at school  I participated in the Collegiate Club Water Polo program. I was fortunate enough to be part of a program that went to the Collegiate Club National Championships all 4 years, making it to the National Championship game every year. The lady Spartans were back to back champions 2001 and 2002.

I met my best friend and future husband Brad in 2006, right when I got my first full time “real” job at MPI Research, now Charles River Labs. We married in 2008 and welcomed 2 amazing kids Samantha (2010) and Mason (2012) shortly after.  Samantha joined the JAWS green group in fall 2016 and loved it. Mason joined summer 2018. I started out coaching the Green Group right after Masons first season. I will start coaching Green and White this season. I have loved getting back into coaching and look forward to all the amazing seasons to come.

Hope Schaaf Coach - Green Group

Hello! My name is Coach Hope and I am so excited to be involved with JAWS again this season! I’ve been involved with the Jenison Aquatic Center for most of my life: In 2009, I started swimming for JAWS (called JAG back then). I swam for Jenison’s junior high and high school teams (2012-2017) and continued with the age group team through my senior year of high school. I graduated from Jenison High School in 2018. I loved having competitive/age group swimming as a part of my life and I knew I couldn’t wait to continue sharing my passion for the sport as a coach. Because of this, I volunteer-coached during my last two years of high school. 

I originally started working for the Jenison Aquatic Center in the summer of 2017 as a lifeguard. Shortly after that, I began instructing swim lessons and received my Water Safety Instructor certification. Then, in 2019, I coached my first season as an “official” coach. I still work in all of these positions…in other words, I'm around the pool quite a bit! 

As of the 2021-2022 school year, I am a senior at Hope College where I study Comprehensive Elementary (K-8) Education & K-12 Spanish Education. During the fall semester, I was an intern at El Puente (Jenison’s Spanish Immersion elementary school), and I will student teach in the Forest Hills school district during the winter/spring semester. After I graduate in May 2022, I plan to become a Spanish immersion or Spanish specials teacher somewhere in West Michigan. 

When I'm not at the pool, I enjoy playing tennis, singing, playing the piano/accompanying, and spending time with family & friends.

Sam Sager Coach - Green Group

Hello, My name is Samantha Sager. I am a senior at Grand Valley State University where I am double majoring in Secondary Education for Group Social Studies and History and a Minor in English. I also have the privilege of being the Vice President of the GV Swim and Dive Club.

I started getting involved in Jenison’s aquatic programs at the beginning of this year. In addition to coaching I also teach lessons and I am a certified lifeguard.

Greg Miller Coach - Green & White Group


Wyatt Sloan Coach - Green Group


Stephanie Rose Coach - White & Green Group

Hello JAWS families! My name is Stephanie Rose, and I am a green group coach and a white group sub. This is my 3rd consecutive winter coaching. My love for swimming began at the ripe ol’ age of 5! And continued through high school. I graduated from Jenison in 2003, and went on to college at Grand Valley State University, where I spent 6 years (undergrad, and grad school) becoming an Occupational Therapist. I have now found my home at Mary Free Bed working with the prosthetics team during the daytime hours.

Growing up, I loved swimming so much that as a sophomore in high school, I began lifeguarding and also teaching swim lessons at the “old” Jenison pool. I continued on working at the pool through my graduate program at Grand Valley State University, and briefly “retired” from coaching and teaching swim lessons when I started working full time as an Occupational Therapist in 2009.

I came back to the pool when my daughters showed interest in swimming. My heart was so full being back in the pool when my oldest, Liliana, started swimming at 5 years old, 5 years ago! I was asked to start coaching when my youngest, Nicoletta, began swimming at 5 years old! I haven’t looked back since then! I truly enjoy coaching the young, first year swimmers. I enjoy watching them grow as little swimmers and becoming more and more confident in the water.

In my spare time, you will first catch me with my kids and husband. Our house is full of fur babies, 2 pugs and 2 cats as well. My most favorite extra activity is hanging out at our lake house, bonfires, boating and hosting friends and family at the lake. I am really looking forward to a great season!

Jenna Blanchard Coach - Green Group

Hello! My name is Jenna Blanchard, and I am SO excited to be back as part of the pool. I started age group swimming when I was 8 years old and never looked back! I continued with JAWS, competing in both the winter and summer programs. I swam on the high school team at Jenison and graduated in 2017. During my time, I was All-State, All-American, and a captain my senior year. I also volunteered as a coach of green group my senior year of high school.  


Since then, I moved to Tennessee where I completed my Bachelor of Science in Nursing at Lee University. My summers were spent in Colorado as a backpacking and rock-climbing guide. I recently moved back to West Michigan and this season I will be coaching green group. Outside of the swimming world I enjoy spending time with my black lab pup, skiing, drinking iced coffee, and  spending  time outdoors.  

Jake Boender Coach - Green Group


Jill Berry Coach - Green Group

Hello, my name is Jill Berry.  This will be my third season coaching for JAWS.  I have many years of personal swimming, coaching, and swim lesson experience.  I began swimming for an age group team when I was 4, continued through high school and swam in college as well.  In the meantime, I was a swim instructor starting when I was 14, then following College swim I took a position coaching the Wyoming Wahoo age group team, when that pool closed, our coaching staff was asked to take over at Kentwood’s new pool facility (KAC), where I coached until last summer.  This totals to almost 20 years of experience teaching kids to swim and to love swimming.  This is truly a passion for me and I look forward to working with your children, and assure you that they are in wonderfully caring and capable hands at whichever level they are entering the team.
