Meet the Team

Joel Jansen – Co-Owner

I began my obsession in the fitness industry at the matured age of 14. I watched my older brother do pushups with weighted backpacks on, sprints in the backyard and all sorts of other ‘fitness’ stuff. So naturally, I began to copy him (of course when he wasn’t around) and started reading any fitness and nutrition book I could get my hands on to figure out the newest and greatest secret in becoming the best in any sporting event I participated in.


That deep desire to learn more stayed with me and brought me to Iowa State University where I received my Bachelors of Science in Exercise and Sport Science. That is also where I met my current business partner.

Currently we own and operate 4 nutrition stores in Sioux Falls, SD and Sioux City, IA. After operating these stores for the past 13 years, we decided that it was time to start our own product line and finally deliver what customers have been asking for. So NG NUTRA was created and has picked up speed faster than what we could have ever dreamed of.

On a more personal note. I have been married to my beautiful, caring and loving wife Desire’ Jansen who holds our family together with patience and understanding. The good Lord has blessed us with our son Beckham Jansen who has taught me the simple joys of life again and helps me to slow down. Life is awesome and I couldn’t be happier.


Zack Durr – Co-Owner

My interest in health and fitness began when I was very young as I used to watch my father lift weights and exercise when I was a little boy, from there I started lifting weights and running to get in shape for football in junior high. Like a lot of people I got bit by the workout bug and everything from fitness to bodybuilding fascinated me. In college I studied Biology, Sports medicine, and History, that’s where I met my business partner Joel Jansen.


During college I worked in sales for a large supplement company and that lead to a Regional Manager job in central Iowa and Chicago after five years Joel and I got back in touch and decided to open our own Supplement company in 2004. From there we worked extremely hard and built up to NGNUTRA our Pride and Joy.

NG NUTRA means a lot to me personally, I met my Wife Maria at work and we have three awesome little girls that help out from time to time learning the meaning of hard work, honesty, and Integrity. With twenty years of my life dedicated to helping people reach their health and fitness goals I know we can and will help you too.

Gunar Rang – Business Development

My name is Gunar Rang, some people call me G.  I grew up on an acreage between Sioux Falls and Harrisburg, SD until I was about 12 years old.  Although I moved quite a few times after that, I attended Harrisburg School District all throughout my grade school years.

I played basketball and golf at a young age, which I still do to this day because I love and have a passion for them both!  In high school, I was fortunate enough to play both basketball and golf at the varsity level for 4 years.  Life lessons were learned throughout those 4 years, that is for sure!  Participating in those two sports alone, I received a Gold Letter (7 Varsity Letters), which is something I am very proud of.  After graduating high school in 2014, and contemplating basketball and golf at the college level, I decided to attend South Dakota State University so I could focus more on education and fitness.  After changing my major a few times, I finally stuck with pursuing a Bachelor of Science in Economics.  In May, 2018 I walked across the stage to receive my diploma.  My fitness journey began the summer going into my senior year of high school.  After seeing what hard work and dedication in the gym can do to your body, I fell in love with it.  From that point on, I have not looked back! I truly believe the fitness journey requires a high level of consistency and dedication, it is not a sprint, it is a marathon.  Walking across the stage in Frost Arena at SDSU, I literally had no clue what I wanted to do with my life.  After making an attempt to succeed in the financial industry in the summer of 2018, I quickly realized that was not what I wanted to do with my professional career.  Then came the month of December, when I applied for a position with NG NUTRA.  Right away, I knew this is something I could see myself enjoying, day after day.  I have a passion for this industry, it isn’t just my job.  On December 19th, 2018 I officially joined NG NUTRA and the rest is history!

Travis Cownie – Customer Engagement Specialist

My interest in fitness really took off because of my older brother. He turned his life around with the help of getting in the gym consistently and putting forth more effort than I had ever seen.

I was always in good shape growing up and played in multiple high school sports, but I never felt like I was big enough or strong enough. So while I was in college at The University of South Dakota, I focused on being in the gym in my free time and consulting my brother on proper nutrition and better workouts. When I wasn’t in the gym, I was working on getting my Bachelor’s Degree in Sports Marketing and Media. I’d gone through a couple of changes with my major until I finally found something that I thoroughly enjoyed and could still use in the fitness and nutrition industry. In my last year of college, I took up a part-time job at Science Nutrition on the sales floor and once I had graduated, I started my full-time position here at NG NUTRA working in the digital media department.Currently I am engaged to a beautiful nurse, Theresa Tibbs. We are new house owners and are both looking forward to what the future has to offer us. Fitness has, and will always be a big part of my life.
