Kevin Wilhite


NASM Certified Personal Trainer & Fitness Nutrition Specialist 

I grew up in Saint Louis, moved to Springfield, MO to attend Missouri State University, but dropped out after completing 3 years and moved to Oklahoma City, to open a supplement store (TRIAD) and start a supplement brand (Define Nutrition). I did this because I have 3 major passions in life. My first one is fitness and more specifically bodybuilding. I am a very visual person, so I love to change the way I look and even compete in the Oklahoma NPC. Second is business. I love working hard to grow something, and everything it takes to create a great business. Third and most important is helping people. I have found that the more I focus on helping others, the better I do in life. This goes for our customers as well as the employees here at Define and TRIAD. Not only do I want to create companies that offer the best products and unbelievable customer service, but also a company that creates the most awesome opportunities for everyone that works here.

Originally from a small town in Northern Indiana, I’ve been involved with sports and fitness my entire life. That led to me rowing collegiately at the University of Delaware and then at Oklahoma City University. After I finished up rowing and left school, I found CrossFit as my competitive outlet. I even met Kevin, Vincent, and Chad at a competition a couple of months before their supplement and nutrition store, Triad, even opened their doors! (I think if you look at my order history, I came into the store the first week they were open, and I’ve been shopping here ever since.) It was through competing and coaching as many CrossFit classes that I was able to, that I found my passion: helping people take control of their health. And that’s why when Kevin reached out about working at Triad, I leaped at the opportunity! It was through my work in the store that I learned about Define Nutrition and what they stand for... Simple, science-backed products that actually work. #defineyourself

Born and raised in Oklahoma City, Oklahoma. I grew up playing sports all throughout my childhood leading up to college. After sports, I found myself being extremely interested in fitness. Mostly because I spent all of my childhood overweight and wanted to lose weight. This is where I devoted most of my time in the gym, learning about training, dieting, and looking for help from others. During this process, I had a friend refer me to a place called TRIAD, a local supplement store that genuinely cared and believed in me more than I did in myself and this is when my life took a turn for the better and also when I figured out about Define Nutrition. Since starting my journey, I’ve lost nearly 100 pounds and losing that weight completely changed the course of my life. That is why I’m a part of Define Nutrition. To change lives.

The first introduction I had to anything fitness related was my friend's dad showing us Ronnie Coleman videos every weekend when I spent the night. Instead of renting movies from blockbuster like normal kids, his dad had us watch all his dvds with him. After that it was sports throughout junior high and high school. When I graduated I didn’t have any sort of outlet to keep myself in shape, so I decided to try going to the YMCA and just lift weights. Immediately I became addicted. I met some of my closest friends at the YMCA and I became a sponge to everything fitness/supplement related. I slowly began to notice that not everyone in the fitness and supplement industry genuinely wanted to help people. It was all about the money. So I was always hesitant about what I took in, information wise. Alfonso and I worked together at the YMCA and initially when he mentioned TRIAD, I had my usual skepticism about it, but once he explained how they separated themselves in education, personal involvement, and overall care for his individual needs, I was sold. Almost two years later, I had the opportunity to be hired on part time and I jumped at it immediately. Couple that with the opportunity to be a part of a supplement company that genuinely cares about what goes into their products and takes the knowledge aspect seriously, and I cannot be thankful enough. We’re here to change the world, one life at a time.

About two years ago I moved from Clinton, Oklahoma to start something new for myself in a place where I had more resources. It has always been my intention to help people live a better life using my experiences as my motivation. Starting in high school I got into sports, which slowly got me into working out at the little box gym our school provided for athletes. Slowly but surely I started learning more and applying it, almost too much. At the end of 2015 I decided to make a decision that changed my perspective for good. I decided that I wanted to lose weight. Little did I know what I thought was going to make me happy, made me feel so out of control. Anorexia was a Demond, and it was a Demond that I listened to for three years. Even though that time was so dark I wouldn’t take it back. That experience is what has made me be so passionate about helping others. When I moved out on my own, I realized that I had to move on. There are bigger things in life than feeling so in control. After I realized that I had to change and put 100% effort into what I wanted to achieve in the long term instead of relieving urges of my eating disorder in the short term. In January 2019 I stumbled upon TRIAD. I walked in and immediately was welcomed by a couple of dudes. One of my first questions was about gaining weight. It was hard to ask but I felt comfort knowing these guys genuinely wanted to help. After that I just kept bothering them and I guess they liked me.

I grew up in St. Louis and went to Missouri State University for college. I was an 18-year old told that I needed to figure out what I wanted to do for the rest of my life and pick a major; I only knew that I wanted to help people in some way, so I got a Bachelors in Social Work. I enjoyed it for some time but learned it wasn’t for me.

I have been an active person my whole life, but when I was in college I met Kevin. He was passionate about fitness and nutrition and made me want to be more consistent at the gym and with my diet. Time passed and he decided he wanted to open a retail supplement store and start a supplement line with Chad and Vincent. They wanted to create something for everyone and make it unlike anything else. They all would spend hours formulating products and contacting manufacturers. Kevin and I would sit in our room and spend hours brainstorming names and making different logo options until Define Nutrition came about. More time passed, we moved to OKC for the store, and Define continued to develop and shortly became a reality. I loved what the brand stood for and loved being a part of it from the beginning. It wasn’t until recently, Kevin asked me to come on as a (paid) employee. I now feel like I can actually help people and be a part of something bigger. #defineyourself

I'm Stanley the Supp Pup! I'm the one that really runs things around here.

I'm originally from Springfield, Missouri, but moved to Oklahoma City with Alyssa and Kevin in 2015. I've always been active and great with people and although I enjoyed living in a college town, I feel I have finally found my niche at Define.

I like stretching in the morning and going on long walks. I found that when I am more active, I am more productive throughout the day.  I sniff more trees and chew more bones on the days I stretch when I wake up. Being around a lot of people, I gets a lot of treats. I make sure to keep my diet in check and get some exercise throughout the day by digging holes, chasing squirrels and going to the park. I also enjoy naps; I make sure to keep my stress levels low by getting a full 14 hours of sleep a day and by getting lots of pets throughout the day. There is also scientific evidence that petting a dog reduces a person's stress levels, so I'll be there when you need me. I do what I can to help.
