About the Owners

Yolanda and Nick Filandrianos

Nick Filandrianos is a second-generation locksmith. His uncle introduced him to the trade in high school, and he worked as a locksmith part-time through college, started his own locksmith business about halfway through, and left school to run it full-time when his first child arrived. He went on to run a locksmith operation in Southeastern Massachusetts that held a AAA account covering Cape Cod, Plymouth County, and Bristol County, and cut thousands of car keys there.

He's also a contractor. He holds a general contractor license in Massachusetts, owns a roofing company, and renovates investment properties, which supports the commercial door and frame work.

He has extensive commercial experience working on storefronts, federal, and military installations in multiple states. His specialties are master key systems, exit hardware, and door repairs and installations, and he prides himself on his skills in these areas.

Lion Locksmith & Security was founded in July 2025 after Niko relocated to Florida from Massachusetts. He first tried combining locksmith and garage door work under one brand, but it didn't work out as planned, so he decided to focus on locksmith and security only.

Niko speaks Spanish fluently and learned it while living in Honduras.

Yolanda Filandrianos handles most clerical duties for the company, including invoicing and job scheduling.
