Meet the Coaches

Nelson DeOliveira

As far back as I can remember, my life has always had sports in it. What started out with youth soccer turned into a passion for multiple sports. My high school years included 4 years of football, wrestling and track. Faced with a changing world, I enlisted in the Army National Guard in the summer of 1995. I proudly served as an Infantryman from 1995 to 2007 and left as a Sergeant First Class with one overseas deployment. My education continued at Kean University where I graduated with a degree in Criminal Justice in 2000 and played football and lacrosse during my stay. A career in the NJ State Police soon followed with a graduation from the academy in May of 2001. My exposure to law enforcement motivated a jump to self-defense and firearms training. I chose the path of Krav Maga and am currently certified as both a civilian and law enforcement instructor with Krav Maga Worlwide. Ever eager to continue my training, an excellent opportunity presented itself here at Tenacity Fitness. Upon getting certified in Group Fitness/Boot Camp Instruction and Sports Specific Training, I joined the amazing crew here at Tenacity. I look forward to helping you all meet and exceed your fitness goals.
