Shaun Kostka

Managing Director

I became a certified life coach and certified personal trainer after I had an experience with going into atrial fibrillation also known as afib. After that, I saw life differently. It became clear to me to be healthy and live a longer life rather than eating everything I can just because I enjoy the taste of the food. I have a new mindset that gave me a better outlook to see what my potential was. I found AV360 and started with the basics of nutrition and personal training. After working with Dr. Alex for six months I decided I’m the type of person that likes to help people anytime someone needs me. I’m always there to help whenever people need assistance and I decided that my life would best be fulfilled by helping people get healthy like I was doing. I’ve come along way in my journey I’m still not done yet but I’ll get there.
