Meet Jim Ambrosius!
Hey everybody, my name is Jim Ambrosius. I am passionate about sharing my knowledge with baseball players, softball players and coaches. What makes me qualified to teach the game of baseball and hitting in softball? Here are my credentials. As you’ll see, I’ve had good fortune to experience a lot with the great game of baseball:
Collingswood Panther and Brooklawn Legion – While playing for Collingswood, I was a 2-time member of the All-South Jersey 1st Team, and a one-time All-State member. I was named to Collingswood’s Athletic Hall of Fame in 2010. I played for Brooklawn American Legion, where I was widely recognized by many as the most accomplished American Legion baseball program in the United States.
ECU Pirate – I played at East Carolina University on a full scholarship. I had a solid career at ECU while battling with arm injuries.
Explorer to Phillie – After 3 years of recurring arm injuries, I decided I wanted to convert from a pitcher to a position player. That is when I transferred to LaSalle University to play outfield. I had a good year offensively, and I ended up signing as an undrafted free agent with the Philadelphia Phillies. I had a good little run with the Phillies, however, as my arm injury persisted, I knew my playing career was coming to an end. I then discovered I wanted to take my knowledge elsewhere.
Coaching – My first coaching experience was as a pitching coach at LaSalle University. However, I wanted to run my own program, so I decided to take on a high school coaching job. In my 12 years as a varsity baseball head coach at Kingsway Regional HS and Williamstown HS, we won 6 conference titles. In my 9 years at the helm of Williamstown’s baseball program, we won 5 conference titles. During the final 5 of those seasons, Williamstown was regularly ranked in the top 15 teams in South Jersey. In my 2 years as a pitching coach for Brooklawn American Legion, we won 2 state championships. In my 2 years as head coach of West Deptford American Legion 20 years apart, 43W-8L in 1999 and 23W-4L in 2019, our teams had a combined record of 66 wins and 12 losses, coming up just 2 wins short of making the American Legion World Series in 1999. Over the years, I’ve also worked with 1 big-leaguer, 7 pro players, 30+ Division I scholarship players, and over 100 college players. Working with these dedicated players has helped me to understand what it takes to be great at the sport.
Complete Game Baseball and Name Your Sport – In 2014, I started my own private instruction business, Complete Game Baseball. I’ve worked with hundreds of players in a one-on-one, small group, and team setting over the past 7 years. Now, I have taken my business over to Name Your Sport, where I can train using HitTrax equipment.

My son has been with Jim since he was 9 yrs old. We completely committed to his teachings and couldn’t be happier with the progress. He is now 12 and has such an advantage over most hitters his age. The knowledge, teachings and commitment Jim provides to his clients are unmatched. Some instructors pitch balls and take your money; with Jim, your child is not only improving, but learning the components of the swing, why they are important and how they come together. He provides an education which enables players to really grasp what they are doing and why. If you’re looking for an instructor that truly understands what it takes to elevate your child’s hitting to the next level, give Jim a call.

I took my son to Jim after getting nowhere with his previous instructor. Right away, I noticed Jim’s attention to detail and a turnaround in my son’s swing and confidence. Jim’s knowledge of the game and translation of that knowledge has paid off! My only regret is that we didn’t go to Jim sooner! I highly recommend Jim Ambrosius if you’re looking to enhance your son’s baseball development!!”

“After my son AJ started his next journey in baseball playing 13u on the “big field,” he struggled at the plate and I began to wonder, ‘Is this it for his baseball days?’. He started working with Jim in September. Since then (the remainder of fall season and beginning of spring season), AJ is arguably his team’s best clutch hitter…nobody better in the business than Jim Ambrosius!”
Mike AHead Coach, 13u SJ Young Guns
“My son has been a pretty good hitter since eight years old, but when he hit 13u and the big field, the struggles began. A fellow coach whose son was seeing success on the big field recommended Jim to me. Jim has made a huge difference. He is able to break down the science of hitting and explain it in terms that kids can understand. I have witnessed him progressing towards success with all age groups. Hitting is not different for different ages, there is the right way and the wrong way and Jim makes sure all his students learn the right way.”
Dr. Charles FSuperintendent, Monmouth County Vocational School District/Head Coach, 13u SJ Young Guns
“Jim Ambrosius has single-handedly been the the most impactful and influential individual on my coaching career. Having coached alongside “Coach Ambro” for two seasons, I learned the game inside and out, and how to develop young men into talented baseball players and responsible citizens. More importantly, I learned what it took to be a leader and to demand excellence from my players.”
Dan FHead Baseball Coach, Waldwick High School
“Coach Ambrosius has been instrumental in getting my son’s baseball swing ready for high school and travel competition. Formerly struggling with pull-side grounders and weak fly balls, he now drives gaps and hits with power. Jim’s instruction of how to get on plane early and apply shoulder angles to have success in driving the ball to all fields is second to none.”
