Coaches Bios


Jeff Bandle: Greetings!  I was born and raised in Southeastern Wisconsin and am a graduate of West Bend East High School.  I also graduated from the University of Wisconsin Milwaukee.  This will be my third year coaching club volleyball.   My two years coaching club I was a 12-1 and 11-1 coach.  This year I will be coaching the GForce U11 Girls.  

Playing volleyball has been a passion of mine for the last 30+ years.  I resided in Jackson with my beautiful wife Christie and daughter Lilly.  Outside of volleyball I enjoy motorcycling, travel, exercise, technology and spending time with my wife and daughter.  Playing and coaching volleyball are things I am truly passionate about.  I look forward to seeing some fresh faces and passing along my love of the sport.

Michelle Rundberg:  I have been playing volleyball for many, many years.  I have played continuously in adult leagues since graduating from college.  I am excited to work with the girls to pass on my enthusiasm for the game, helping them to develop their skills while learning how to work together as a team.  My husband Don and I reside in Jackson with our two daughters, Shayla, a seventh grader at Badger Middle School, and Skylar, a fifth grader at Silverbrook Intermediate School.

Playing sports and teaching fitness classes has been a huge part of my life.  I played volleyball at Racine Case HS and with Great Lakes Volleyball Club.  My first volleyball coaching experience also came with the club after I aged-out of the program.   The past several years I have been coaching my two daughters at St. John Lutheran School in Random Lake.  I enjoy sharing the passion for the game with my girls and all the girls I've been blessed to work with over the years.  I am excited to be a part of the G-Force Volleyball Club Coaching team and strongly believe in the philosophy and direction the club is heading this year.

I'm a graduate of UW-Milwaukee and working professionally as a Community-Based Sign Language Interpreter.  I also teach fitness classes with the Kettle Moraine YMCA Ozaukee Branch and Form & Fitness in Grafton.  I reside in the Random Lake area with my husband, Marty, and two daughters, Payton & Greta and sons Van & Levi.  I look forward to an amazing club season!!


Volleyball has been a part of my life for as long as I can remember. I started playing in middle school, played club volleyball throughout high school, was a part of two high school state championship teams in North Dakota, and went on to play four years at UW-River Falls. I've been coaching since college. I've been a part of middle school and high school programs all over the state. This will be my first club coaching experience, and I'm so looking forward to working with a 13s team! I like my teams to have their basic skills and court movements be second nature by game time so they can focus on just playing in the moment of the game. I also love challenging my kids to hustle and scramble in practice, so they're used to fighting for points come game time. 

My degree is in Physical Education with minors in health and coaching. Former teacher, current fitness studio owner of En Fuego Fitness in West Bend where I teach classes, do personal training, and also teach youth conditioning and training. I live in Jackson with my husband Luke and my four girls Rory, Kendra, Riley, and Frankie. 


Bert Bertrand:  Volleyball is a passion of mine as I have played competitively in the local recreation leagues for 37 years.  I also ran the league for 15 years in Grafton.  I coached the Varsity and Junior Varsity teams at Grafton High School for four years form 1998-2001.  Currently,  I am entering my third year as coach for St. Joe's Grafton girls and boys 5th, 6th and 7-8th grade teams.  My previous club coaching experience was with Ozaukee Wave Volleyball Club for the last 7 years and I served as a U17, U16, U15 and U12 girls coach.

I am excited to join G-Force as a member of the coaching staff and look forward to a great 2017-18 season!


Jessica Jacklin: This is my 11th year as a a volleyball coach.  I have coached club volleyball for 10 years and this is my 3rd year with G-Force.  I also am the head coach for the David's Star Evangelical Lutheran School 7/8th grade team.  

I enjoy the process of coaching.  My passion for helping kids become stronger individuals grows each year as I feel that as much as I may teach them, they teach me in return.   I love helping create a learning environment for kids that is not only about skills, but also how to be good team mates, leaders, learning to think outside the box, be more confident and develop a strong work ethic.  These are essential things needed to thrive in life as people and as athletes.

Each season brings with it a journey.  I look forward to the 2017-18 season.

Rob Donaldson:  

Currently, I am starting my 17th year of coaching.  I am in my 2nd year as Grafton Girls JV Coach.  I have coached at the club and high school levels while coaching both girls and boys ages 11-18.  My main goal is to give each player the confidence in themselves to achieve and excel in the game as well as their everyday lives.  Finding that balance to help each athlete improve as a player and person while motivating them to reach their goals is a passion.  I look forward to this years club season and joining G-Force!




This year will be my 6th season as a coach for the 6th-8th grade team at Calvary Lutheran in Mequon as well as my 2nd year coaching with G-Force Volleyball Club.  Volleyball has been a part of my entire life and I played competitively through high school and also play locally in leagues and tournaments.  I earned my bachelor's degree from St Norbert College and am currently working on my MBA through Arizona State.



I began coaching volleyball in 1971, it's original inception as an interscholastic sport.  My first coaching position was with James Madison High School where I served from 1971-1978.  During that tenure we won a State Championship in 1977 and were State Runner-Up in 1978.  From there I became the Head Coach for Germantown High School in 1980-2013.  During that time Germantown achieved 12 Conference Championships.

Bill and I started GForce in 1997 and have coached for the club every year.  This year we will be the U15 Select Coaches for GForce.  

Germantown did not have a middle school program until 1987. Bill and I helped implement a program and coached thru 2009.  Bill also coached the Junior Varsity team for Germantown High School from 1988-2013.  We also ran a summer camp program with the recreation department from 1990-2013

I was inducted into the Wisconsin Interscholastic Hall of Fame by my peers in 2013.  


Matt Jaworski - 15 GREEN

I grew up in the Milwaukee area first playing basketball and baseball.  I started playing volleyball for the first time when I was a brother in the middle of 2 sisters who were volleyball players.  After high school, I went to UW-Whitewater and played for 2 years with the mens club volleyball team.  After college, I played in a handful of leagues, mostly with mens and women players that I first met at UWW.

Unlike others that I knew from UWW, I did not get into coaching right away because I went to graduate school and got married and had 2 daughters.  However, as my daughters got older and began to play  sports that I used to play, I started to get involved into coaching.  I am currently the JV girls volleyball coach at Cedar Grove Belgium High School and look forward to my first year with G-Force.

Outside of volleyball, I am a VP in the Credit Risk Review division of Associated Bank and spend as much time as possible with my wife and 2 daughters, Clare and Allie.  One of the primary things I try to get players to understand is to focus on having a great attitude, working as hard as they possibly can, and to solidify good technique.  If they get after those 3 things, winning usually will come along for the ride.


This is my 9th season coaching for G-Force where I have coached teams from 12's through 15's.   My passion for coaching comes from being able to teach players that there is no limit to what can be accomplished with effort and a good attitude.  My coaching philosophy embraces the fact that the learning process requires players to make mistakes and helping the players through the struggles that go along with learning.

In addition to coaching at G-Force, I coordinated volleyball at St. Boniface in Germantown for 5 years, coached at St. Mary- Menomonee Falls for 2 years, and coached at First Immanuel Lutheran School in Cedarburg for the past 2 seasons.  

I have enjoyed the people I have met through volleyball.  On any given day of the week between August and May you can probably find me coaching a team or watching players that I coached as they participate for their schools.

I am looking forward to another great season!
