Becca O’Donnell, Fitness Director

Certified Personal Trainer
Education: Bachelor of Science in Physical Education from East Carolina University

Training Philosophy: Diversity and Consistency. I believe that changes in routine can help with progression and reaching goals. Small changes in daily habits can be the difference maker in reaching those goals. I love to change up my clients’ workouts so they are excited and challenged every time they come to Ellis.

Favorite Fitness Activity: Weight Training mixed with intervals of running.

What motivates me: No matter what fitness circuit and workout I create for my clients, they keep coming back from more. I love to see when my clients work hard, their hardwork and dedication motivates me through my own workouts.

Fun Fact: I write a Health and Wellness blog for Main Line Today Magazine!


Willie Owens

Certified Personal Trainer

Education: The Pennsylvania State University, Exercise Sports Science

Training Philosophy: Training is not just about pushing weight.  It is listening, encouraging, and coaching.  More isn’t always better, and pain doesn’t equal a good workout all the time. Calculated caring progression is key, and remember the scale doesn’t tell the whole story.

Favorite Fitness Activity: I love running sprint intervals, and stadium steps and occasionally I like to do chest workouts. 

What motivates me: Philippians 3:14, I press toward the mark for the prize of the high calling of God in Christ Jesus.

Lori Sarne

Certified Personal Trainer

Education: Holy Family University -Elementary & Early Childhood Education (retired teacher of 12 years)

Training Philosophy: Working out should be fun! I am always researching new exercises to keep my clients and class participants interested and motivated. I prefer free weights, stability balls, a Bosu, bands, and body bars over machines for a total body workout. Incorporating core and agility training is one of my favorites as well. I’m not a fan of body weight scales and measurements. The true test is in the change that my clients see in the mirror.

Favorite Fitness Activity: I like doing anything active such as walking, running, playing softball, swimming, taking group fitness classes and of course creating my H.I.I.T. Circuit Workouts.

What motivates me: I am motivated by my kids. They are both tremendous athletes. I am also motivated by my clients. I know how hard they work every day. I won’t lie, I love to eat and that in itself is a big motivator.

Fun Fact(s): I love turtles, cats, and reading. I may have a slight addiction to sneakers. I met Tony Hawk in the early 90s.
