This is what Ella had to say about Bill:

I am a Junior at New Trier High School in Winnetka, Illinois and a member of the Jr. Varsity Bowling Team. Beginning in my freshman year I have been taking private lessons from Coach Spigner as I was brand new to the sport of bowling. Coach Bill has inspired and motivated me in many ways... he has taught me so many bowling skills, for example: proper positioning, body placement, and ball handling techniques. Also, he provided me with the knowledge of bowling balls and equipment that would be best suited for me. Coach Bill has always been positive and encouraging... even when it's a challenge. He would find ways to teach me that were tailored to my specific learning needs. In addition to being an excellent bowling coach, Mr. Spigner has inspired me personally in other ways. He taught me that I could do anything if I put my mind and effort into the task. He believed in me... and his kind and patient personality encouraged me to keep trying! I truly enjoy being around his positive and supportive demeanor! Coach Spigner helped me to see my own potential... and believe in myself. I can't wait to see what the future holds for me.

What Bill had to say about Ella:

Ella is one of my special students who came to me as a freshman in high school after making the bowling team at New Trier High School. She was brand new to the sport.

Things don't come easy for Ella, but she has the three D's – determination, desire and dedication. She started out with a 3-step approach, a conventionally fit 12 lb. ball, and rolled a reverse curve. Because of her work ethic she has developed a solid 4-step approach with a good release using 14 lb. equipment.

This year she bowled her first 200 game – 202 – which happened during the CSL Conference Tournament which was a major breakthrough for her. Since then she has dedicated herself even more to the sport than she had before. Recently she was gifted a ball that I thought would be a good compliment to the 2 balls she had been using. I re-drilled the ball for her and the first 7 balls she rolled with it were 7 perfect strikes – her biggest string of strikes before that was 4. She bowled a 253 clean game – by far her highest game.

This past year as a junior she was on the JV team and got one start as a Varsity player. At the end of the season she received the most improved bowler award and her 923 series in the CSL Conference Tournament was the highest JV score in a match for the year. Her goal is to be a varsity starter her senior year, which she is well on her way to becoming.




Bobby Habetler

This is what Bobby had to say about Bill:

I first met Bill six years ago and have been working with him ever since. I really love what Bill has done with my game because he works on the small parts, which makes my margin for error much larger. Bill knows my strengths and has worked with me on identifying my weaknesses. He always tells me, "This is a long-term solution." I love that because it makes me realize that nothing can be fixed immediately. Bill helped me prepare for the 2021 PBA Jr. Regional Tournament in Wauwatosa, Wisconsin by working on some different hand positions that I ended up using bowling in the tournament. I ended up finishing in 5th place in the star-studded field. I firmly believe I have an advantage over my competition because Bill is my coach.

What Bill had to say about Bobby:

Competitive bowling is in Bobby's DNA as his great-grandfather Rudy Habetler won the 1953 ABC Masters. Bobby is mature beyond his years – very calm, intelligent, and level-headed. These attributes are evident whether he is bowling as an individual or with a team. As you can see in the video, he has the same pre-shot preparation – never rushing his shots and always is set mentally before he starts his approach.


Bobby is slight in stature but has a big game. He's a two-handed stroker and his medium speed and rev rate match up perfectly. He has the ability to play anywhere on the lane and uses his equipment wisely. He handles high scores with composure and doesn't get rattled with a bad score. If he's struggling, he's very good at staying in the present and working to figure out a solution. If he's bowling good, his attention is just as focused.

He is a pleasure to work with, as he is very inquisitive and is always looking for answers and ways to improve – many things we work on are pretty advanced and way beyond someone his age. I'm looking forward to helping him achieve his bowling goals.




Stephanie Zagar

This is what Stephanie had to say about Bill:

I first met Bill three years ago and I've been working with him the past year and a half. What I really like about Bill is that he helps make what I already do well with my game better and at the same time minimize my liabilities. Bill has shown me a side of bowling that I really never knew, and I always leave my lessons with something to work on to improve my game to make me the best version of me. I feel comfortable and relaxed around him and he makes sure I understand clearly what he wants me to work on at home. Bill has led me to not only one Wisconsin High School State Singles Championship but back-to-back Wisconsin High School Singles Championships in 2020 and 2021. I'm looking forward to what we'll work on next, and I can't say thank you enough for helping me reach my goals Bill!

What Bill had to say about Stephanie:

Stephanie is a delight to work with – she has a great swing, rock solid finish, wonderful lane sense, touch and a great work ethic.

She came to see me right before the Wisconsin State High School Championships the past two years and those sessions brought her some great results. This year she was struggling – she couldn't get her ball to roll and hook which affected her carry and her visual line-ups got off. I had her move up about 12" on the approach and coupled with that I told her to think about her back swing going no higher than waist high. Even with her feeling her swing was very low, it still was a ball width over her head--which was fine--the goal was to slow everything down on her back swing. Then we worked on opening up her target line so it was in line with her arm swing.

The final piece this year was an equipment adjustment. I knew the Wisconsin High School Championships were being played on a challenge condition which would require accuracy and controlling the lane front to back so I wanted her equipment to basically hook very early so her ball didn't blow through the break point. I used a 180 grit abralon pad and hand-sanded her solid asymmetric and pearl symmetrical bowling balls until they were very dull which I knew would hook early enough so she could line-up normal and control the lane.

What we worked on paid off – she won her second straight Wisconsin High School Girls' Singles Championship--the first two-peat in it's history.
