Ronnie Quinn

Born in South Korea but grew up all over the United States as a military 'brat'. Ronnie has been surrounded by firearms all his life due to his father's extensive military service. He learned his firearm fundamentals at and early age from his father James, who's impressive Naval service as a Chief Gunners Mate included Weapons Division lead Petty Officer, Shipboard Small Arms Allowance supervisor, training of security and standing duty armorer.  James was also in charge of Mount 52 left gun, twin Mark-12 5"/38 caliber gun and was a qualified expert on the 1911 .45 cal pistol, expert M-14 & a sharpshooter on M-16.

Coming from this background, Ronnie started shooting at a very young age often competing for fun with his father's military buddies. This tradition has carried into Ronnie's life - having taught firearm safety and proper firearm handling to his 4 children as well as extended family. He continues to shoot in his free time and enjoys learning all he can about techniques and shooting styles.

Mow Mow

 Patron Greeter

Born in Escalon CA, Mow Mow has been a part of LGR for over 8 years. She loves to greet our patrons every day in the ProShop. When not in the office she can be found in a small box somewhere or begging for treats. She loves chasing lizards, field mice or just finding a way to get back into the office to greet her friends. Mow Mow, being a special kitty, understands that not everyone can be around her, so she is more than happy to leave the office if anyone requests it due to allergies.
