Director of Operations

Steve had a love of all sports growing up and participated on many different teams, including soccer, baseball, basketball, football, diving, and gymnastics.  While he enjoyed all of those sports, it was gymnastics that truly captured his interest.  He competed all four years for the College of William and Mary’s Division 1 gymnastics team. 


After college, he stayed involved in gymnastics as a part-time coach and judge while building a career as an Information Technology consultant. Now as a father of five children, he enjoys playing games with them and watching them develop a similar enjoyment in their sports of choice.


Over the last several years, Steve has continued playing sports in local indoor soccer leagues and has become fond of running, completing two marathons, a half marathon, and the local Barber Beast on the Bay the past two years.  The obstacle course race was one of the more fun and challenging events he's completed, leading to an increased desire to bring a Ninja obstacle training facility to Erie.

Parkour/Freerunning/Breakdancing/Tumbling & Flipping  Instructor

Nate developed a love of movement early in life but had no physical outlet that could hold his attention. It wasn't until age 16 that he and a friend taught each other basic tumbling skills in their backyards. Nate was quickly recruited to be a competition cheerleader during his senior year of high school. After taking third place at CCC Nationals, he graduated and was hired to coach floor tumbling over the summer before attending college that fall. That experience led to several other coaching positions over the next 15 years. Meanwhile, an exposure to breakdancing and free running during his time in college opened up new doors and unlocked new movements. He began to teach various breakdance classes between Meadville and Erie, but eventually returned to coaching in the years to come.


Nathan earned a USASF certification and continued to coach floor tumbling until he moved to Los Angeles in 2014. He informally continued his education while studying the diversity of movements and styles the West Coast had to offer. Upon moving home in late 2015, he resumed his role as a tumbling coach as well as an instructor for free running and parkour. He has most recently branched out into the world of ballet partnering and has had the opportunity to perform several times in the last three years.


As a lifelong fan of movement in all its various forms, he strives to continuously learn and to pass those lessons onto others.

Josie Plaster

Gymnastics/Ninja Instructor

Josie is currently a sophomore at McDowell High School and was born and raised in Erie, Pennsylvania. As growing up with a family who loves sports, staying athletic has always been important. These sports provide her with long-term friendships and help make her passionate about educating those around her. Watching improvement in these athletes keeps her engaged outside of her personal teams. 


Josie had been a gymnast for 10 years when she decided to move on to softball and volleyball. Continuing to love the sport after withdrawing from competition, coaching felt as a way to stay connected. 


Working with children ages 3-5 through McDowell Child Education Profession, provided a realness for being with young children on a daily basis. Meeting with the same classroom of children for 90 days a schoolyear, helped her build a closeness not only as an educator but also as a friend. Becoming knowledgeable provided her with the motivation to take her enthusiasm outside of the classroom and into the gym.

Amanda Yacone

Gymnastics Instructor

Meet Amanda, a passionate coach and a lover of sports! Amanda has been involved in sports since a very young age. She started as a gymnast and eventually started coaching gymnastics at the young age of 14. Gymnastics continued to be Amanda’s main sport as she competed for her high school team all 4 years as well as participating in competitive cheerleading, field hockey, and track. She attributes learning a lot of life skills from the sport of gymnastics. Some of those skills include a strong work ethic, perseverance, confidence, and teamwork.

Amanda continued her journey in the fitness world and later became a figure bodybuilding competitor. She also pursued her degree as a physical therapist assistant to further her knowledge in the field. With her experience, she owned and operated i9 sports, a youth sports program. She has also coached McDowell’s JV cheerleading team.

As a mother, Amanda wanted the best for her children as she searched for a gym that would provide a fun, positive, and safe experience while also teaching proper technique. That's why she came to be a part of the Sinai Sports team!

Amanda's passion for coaching goes beyond the gym as she is a wife, mother of two kids, and a dog mom to three dogs. On top of that, Amanda runs her own small business as a portrait photographer. In her free time, she loves to be outdoors in warm weather, go on vacation, and watch movies with her family. 


Alyssa Craig

Gymnastics Instructor

Alyssa is an Erie native and has always lived an active lifestyle. In addition to gymnastics, she played soccer and ran track in high school. In college she participated in club gymnastics and began coaching in Butler, PA. At this time she earned certifications through USA Gymnastics and continued taking courses to better her coaching knowledge.


Once she moved back to Erie, she found a coaching spot with the infamous Coach Carl at Family First Sports Park and eventually followed him to Tumble 84 for many years. Summer 2023 Alyssa decided to take the leap to Sinai Sports to help with the new competitive team as well as recreational and adult classes.


One of the biggest goals Alyssa has as a coach is making sure to provide a safe, comfortable, and fun environment for her athletes. Gymnastics is as much a mental sport as it is physical, and she wants kids to remember that it’s ok to fail as long as you keep moving forward!


Fun facts: Alyssa trains and competes for Sinai Sports' Team Samurai (Ninja), and has gone to adult gymnastics camp with Chellsie Memmel the last 2 summers!
