Grant Lavelle

Lead Instructor | Owner

My name is Grant LaVelle, I am the owner of Maximum Life Expectancy. I started teaching Marksmanship and firearms skills in 1992 after completing the Marksmanship Instructor School at Camp Lejeune, NC while serving in the United States Marine Corps. After leaving the Corps in 1994, I started a career in law enforcement and continued to use the skills learned. Along the way I have taken numerous advanced instruction courses to improve my skills as I served in a variety of roles from Patrol, Investigations Bureau, SWAT, Sniper and Range Officer. While still in law enforcement I began working for MSSU as a Firearms Instructor for the Regional Police Academy and was their first instructor for MSSU's CCW program. In 2008 I decided it was time to start my own business in order to offer citizens with a better alternative to the normal training product available. I consider it an honor to provide you with quality firearms training.

Jared Andrews "Thumbs Keller"

My name is Jared Andrews. I possession the worlds longest thumbs.  Big deal you say, until you see my mag changes!  I'm so much faster than Grant and "25 Mike" that all you see is a blur.  Well all joking aside Mike is at least close to my speed, Grant is old and slow (no joke).  I'm a Sage Dynamics Eleanor coin owner, can Grant or Mike claim this, nope.
