"Passionate about inspiring others"


My name is Salima Rockwell, and I am beyond excited to begin a new journey in my lifelong quest of helping people improve their lives, minds, and hearts. I am a former 3 time All-American Setter from Penn State University and the starting setter and Captain of the US Women's National Team. Volleyball has been my passion since I can remember, and naturally as a setter- leading, motivating, and helping others succeed is what I love to do most. After retiring from playing, I became a Division I Women's College Volleyball Coach with most of my years spent as The Associate Head Coach at The University of Texas and Penn State University. Between my time as an athlete and my coaching career, I have participated in 10 Final Fours and Won 4 National Titles. During my 18 years as a college coach, I can say without question, that the most rewarding part of my job was mentoring and guiding my athletes as competitors, students, and people and helping them navigate life as a college student. 


Since I retired from coaching two years ago, I have spent my time as the Director of Volleyball Innovation at The Mamba Sports Academy, The President of the Junior Volleyball Recruiting Association, The Assistant Director of Training and Recruiting at Austin Juniors Volleyball Club, The Owner, and CEO of Volleylytics LLC. Consulting and have consulted for many College Programs over the last two years. Most recently I became a Color Commentator for College Volleyball for ESPN, Fox Sports, and The Big Ten Network, calling over 30 matches last season including the NCAA Selection Show, and the pre and post-game shows for the National Championships in Pittsburgh.

I am so excited to begin work in my latest venture as the Co-Founder of MindGrowthLab, working with athletes, their families, and volleyball coaches across the country. It's something I have done for many years, and I can't wait to take it to the next level by providing a process and a strategic plan for all of our clients and their needs. I have a personal and deep understanding of hard work, what it takes to be successful, while at the same time overcoming any mental challenges that might get in your way. Thank you for trusting us to guide and support you through volleyball and life. 

With hope and strength,

"My growth is cultivating growth in others"


My name is Karrie Poppinga, and I’m thrilled to have MindGrowthLab be another resource to help grow and cultivate strong women. I’ve been so lucky to have had teachers, coaches and mentors help me navigate my athletic journey but more importantly, they have helped me root down life lessons that have really helped me grow into who I am. This is why MindGrowthLab was created, namely to give back and support coaches and players in their own growth and development.

I’m originally from Manhattan Beach, California and have lived in Germany in my younger years. I played volleyball for the University of Hawaii and was awarded All American honors and won a NCAA Championship.


After my collegiate career, I continued to play professionally overseas  in Italy and Holland. When I returned back to the States, I stepped into beach volleyball where I was fortunate to play both on the AVP (Association of Volleyball Professionals)  and Federation of International Volleyball (FIVB) for 6 years. I retired from playing professionally in 2001 and pursued my graduate work in Counseling Psychology. I’ve since been raising 2 amazing daughters, and have been coaching volleyball at a junior level and high school while working with adults and teens in Counseling since 2005. What makes this work so wonderful is that I have been at every seat of the athletic table! 

Let's huddle up and grow together!
