“Let’s get better ”

Joshua Kuluris / Founder / Coach

Joshua Kuluris is a Southern California native who currently resides in the city of Laguna Niguel. If he is not in the gym working on his own individual goals or in the kitchen cooking healthy meals, you can find him spending time with his family and friends. His passion for family, fitness, health and helping others get better is the foundation for his business, Konversion Fitness.

With a massive heart to see others get better, Joshua leads by example by practicing himself what he teaches to his clients. His hope is that his experiences and failures will lead to his clients growth and that the community he has built will be a place for anyone, no mater where they are on their fitness journey.
