After graduating from Philadelphia University, Aimee followed her career goals and applied her Fashion Merchandising degree in the retail world. She pursued her dream of becoming a buyer in the industry at a variety of companies such as Lacoste, Polo Ralph Lauren and Linens ‘N Things. Throughout her eight years in retail, Aimee was the first to adopt the latest fitness trend, fad or gimmick, anything to say fit, healthy and sane in the retail world. In 2003 Aimee became certified in Group fitness through AFAA, the Aerobics and Fitness Association of America. Following that certification she became Spinning/Group Cycling, Yoga, Pilates and even a certification in a little known globo-gym device, the Core Pole. In addition to certifications, throughout her tenure in New Jersey she studied Boxing with a Taekwondo specialization from Master Kevin Padilla, who recently traveled to Beijing to coach at the Olympic Games.

In early 2008, after a move to Philadelphia, she was introduced to CrossFit and after watching the Nasty Girl video on the CrossFit HQ main-page; she was instantly hooked! Aimee immediately began looking for CrossFit training courses and her search brought her to the Police Academy in Vassalboro, Maine where she was awarded her Level 1 Trainer under the instruction of Pat Sherwood, CrossFit Level 3 Trainer. Her training and commitment to CrossFit principals began as soon as she returned home to Pennsylvania and began coaching with her "Level 1 CrossFit Trainer" degree. Aimee’s passion and dedication to CrossFit training has taken her physically and mentally to levels she never thought possible. Her philosophy is that, "Consistent CrossFit training promotes a disciplined lifestyle, which in turn creates a sound, healthy body and mind. This discipline transfers into other life pursuits, which help individuals develop a positive self-image and outlook on life." Aimee received her Level 4 CrossFit Trainer designation in 2013 and is currently helping coach at CrossFit Level 1 Trainer courses, Level 2 and CrossFit Kids courses.

Aimee is also a certified personal trainer through the National Personal Training Institute and holds a board of education certified degree in basic nutrition. She is a USA-Weightlifting Certified Sports Coach. She established CrossFit King of Prussia in September of 2008 and established CrossFit Harmony in September of 2013.

Keith grew up in Scranton where he participated in many sports growing up. He played football and baseball from Little League throughout high school. It was easy to stay in shape because of the fact that he was involved in team sports. There was always a regimen to follow that was set up by his coaches. Along with being a football player came an extensive weightlifting program that involved movements such as squats, presses, deadlifts and power cleans. After football ended he remained active and participated in recreational football and softball leagues. He even continued to try to keep up with the lifting program that he had followed for years but it was never the same. In May 2011 a friend introduced Keith to CrossFit. She showed him a video of the WOD “Amanda” on her iPhone and he was instantly intrigued. He came in for the intro and learned that CrossFit involved movements such as squats, presses, deadlifts and power cleans. Before May was over he completed fundamentals and was attending classes four or five times a week. Over the next year Keith completely immersed himself in CrossFit and obtained his Level 1 in April 2012. Shortly thereafter he began interning to become a coach at KOP. He is an enthusiastic coach who finds true enjoyment in helping the members of CFKOP reach their fitness goals. When it comes to CrossFit he considers himself to be a Jack-of-all-trades, Master of none. Which is exactly what CrossFit trains you to be. It specializes in not specializing. His favorite WODs are anything that involves squats or double-unders. His least favorite WODs are ones that involve running or push-ups.

Coach Leda, MPH, CFL-3

Leda came to CrossFit as a way to improve her health and fitness after finding herself 65 pounds overweight and on the verge of chronic disease at the age of 40.  As a stay-at-home mom, with no athletic background, she was at first nervous to start CrossFit but quickly learned to love it.  That was almost a decade ago and her passion for it compelled her to become a coach.  She is a level 3 trainer and a Level 1 Burgener Weightlifting trainer.  She loves learning everything she can about CrossFit and sharing that knowledge with her athletes.  In her spare time, she also runs a podcast called CrossFit Lady that aims to encourage and educate women over 50.  Through coaching and her podcast, Leda hopes to change the mindset of what it means to age for longevity and vitality.



am a NASM certified personal trainer, CF-LV1, USAW LV-2, sports performance coach, Performance Nutrition LV1 coach. Growing up I was never in shape and didn’t start playing sports until the end of elementary school. As a kid I used a pretty bad case of asthma as a crutch to not have to be active or super motivated. Playing football in middle school kept me active at least but looking back I lacked the competitive drive that a lot of other young boys my age were already starting to develop. 


In my sophomore year of high school we got a new strength and conditioning guy for the football team. A guy that was starting this new thing called “crossfit” and he was hoping to open a gym in the area. That guy was Barry Weidner of Crossfit Generation. The workouts were the worst thing I ever did in my life at the time and everyday made me want to quit. While they helped me stay more fit than before my eating habits remained the same and I lacked in drive to change them.

Going through a lost period after high school in my early 20s trying to figure out what to do with my life it hit me that I should probably not spend my whole life in horrible shape. The only thing I knew about working out was the word crossfit so I googled a gym in the area and joined. I did the workouts, drank the koolaid and never looked back. It helped me change my life and I wanted to help others do that same thing.

After recently obtaining her CrossFit level 1 (L-1) certification in April 2023, Jackie is ready to combine her over ten years of personal Crossfit experience with her background in psychology. She has been an active member at CFKOP since 2010, after she earned her doctorate in psychology from La Salle University. Before beginning CrossFit, Jackie had a strong foundation in sports, playing soccer and swimming throughout her childhood. Her favorite WODs are anything that involve heavy lifting not for time and rowing. Her least favorite WODs are ones that contain running and burpees. She is excited to be joining the coaching team at CFKOP and looks forward to helping others with their fitness journeys. 




Having played sports throughout his childhood, Jason was accustomed to having fun while getting a workout. After college, the opportunities to play sports seemed to present themselves less and less and instead of increasing his heart rate, Jason seemed only to increase his pant size. Every year Jason would attempt to work out more but the fun was just not there. He became the person that everyone knows…the one with the home gym being used as a coat rack and the gym membership that hasn’t been scanned in 6 months. Enter CrossFit. After laughing at his wife for reading all of the articles and watching all the videos, Jason decided to give it a try. It took one workout (Chelsea) to humble him and make him realize just how far down the fitness ladder he had fallen. Since then, Jason has completely submerged himself in the CrossFit culture and has seen dramatic results in a short period of time.

Growing up I was overweight, and never really played any sports. It wasn't until after having my daughter in 2006 that I had any serious interest in working out. I started out at a gym with little to no routine, until I began running. However, my running routine became boring quickly, and I needed something more challenging. My best friend told me about Crossfit King of Prussia's on ramp class in 2015, and i figured: what do I have to lose? I was hooked from the very first WOD. Crossfit was the very thing I needed to get into the best shape I have ever been in. One of my favorite things about Crossfit is the confidence I have gained. After completing a workout I feel as if I can take on the world. It's really amazing to feel like I will overcome any challenges. Crossfit has also helped me instill a healthier lifestyle for my daughter , who recently enrolled in the Crossfit Teens class. The guidance and support of the coaches, and the community motivating you to do your best during any workout is what keeps me showing up everyday. The coaches at KOP inspired me to take my CF Level 1 course. I admire their passion for this sport and as a coach, hope to inspire others, and share that same passion. Since taking the level one course, I have also taken the Level two course, and the Crossfit Kids course.

I have always felt connected to movement in some shape or form. I began as a Dancer and Choreographer at age 17. That path took me from New York to California and even Japan, performing, teaching classes and workshops, as well as setting Choreography. I always felt grateful to be able to live art and make a living at it. As the years went by I grew more and more interested in health and fitness and began Personal Training in 2009 (NASM, Action Certified) by 2011 I had began coaching CrossFit. Since then I have continued my education in CrossFit Gymnastics, USA Olympic Weightlifting, CrossFit Level 2, Coaches Development, and currently pursuing my Level 3. I would consider myself a conservative Coach who finds value in the day to day diligence this sport requires. Coaching has always been a great love of mine, and if someone wanted to know who I truly am, they’d take my class.
