Leanne Siewert

Fitness Coach

Leanne is a recent graduate from Benedictine University with a Bachelors in Exercise and Sports Studies. After interning at Functional Effect for over a year, she is incredibly excited to be joining the rest of the team and the FE community.

Growing up, Leanne had a very active lifestyle, which translated to becoming collegiate athlete. During her college years, she struggled with body image and over-exercising, and eventually had to reevaluate what fitness meant to her. She continues to work on that balance and hopes to help others as well.

Due to multiple knee injuries, she had to undergo a relatively invasive knee surgery in the middle of her collegiate athletic career. With a frustrating year-long rehabilitation, Leanne began prioritizing movement that just made her body feel better. In this process she developed a deeper appreciation for exercise, and inspiration for a change in career path.

Leanne looks forward to taking her Certified Strength and Conditioning Specialist exam this coming year and is excited to continue to learn and coach at Functional Effect. She loves the family-like community and can’t wait to help everyone achieve their goals in both fitness and their everyday lives. When she isn’t coaching, you can find her taking pictures, playing with her dog, or finding the next great adventure

Jodie joined the FE team after being a client and making a decision to change her life.  Having struggled with her weight for years, she joined Functional Effect and Weight Watchers, determined to make a change before her 50th birthday.  After losing 75 lbs she gained a new perspective on fitness and nutrition, and decided to change her career to help others with similar struggles.

She earned her BA from Illinois State University in Psychology and MA from Lewis University in Leadership. Being an administrator of a law school for 30 years she personally understands the detriments of a sedentary lifestyle.  After leaving her job at the law school, she went back to school and earned her Group Fitness Certification through NASM.  She now instructs our group fitness classes 3 days a week and also leads several local Weight Watcher meetings.  Her energetic personality, coupled with her passion to effect change, make her an excellent addition to our team.

Jodie spends most of her free-time either rescuing dogs or playing with her three fury children; Garth, Spike and Sam.  She comes from a large Italian family, and married her husband Joe, who comes from a large Irish family.  She now feels blessed to call Functional Effect members and staff her extended family!

Ann-Marie Kouba

Fitness Coach

Anna-Marie has always enjoyed being fit and active, especially having four children; and now that she has twin granddaughters. She never wanted her age to define her abilities, and that is why she trained for a Tough Mudder race. This is when she got the bug for training. It was amazing what her body could do with the right coach in my corner.  She decided after her third race to become a personal trainer. It was scary and totally out of her comfort zone since she hadn’t studied for anything in decades and starting a new career at my age. She took the plunge and became certified from NSCA. She enjoy helping people and this new career gives her the opportunity to help others in another way; becoming better, healthier versions of themselves.  She hopes to inspire people to get fit at any age. Movement truly is medicine.
