Gabriel Montiel Jr
Founder, CEO of Gainline Marketing
Former Sergeant, United States Marine Corps
I'm Gabriel, a former U.S. Marine Sergeant. I served as a Combat Engineer for 8 years. Combat Engineering involves construction, explosive demolitions, reconnaissance, and more. Here are some reasons why I can back up what I'm claiming here.
After honorably discharging in 2022, I immediately got into marketing. I have certifications in Google Advertising and Meta Social Media Marketing, and those certificates can be found on my LinkedIn profile.
I Understand Your World:
My dad has installed tile and granite since I was a child. My stepfather is a general contractor. I'm not some suit-and-tie marketer. I've been around blue collar workers all of my life. Hell I am a blue collar worker, disguised as a white collar worker trying a different path.
Its pretty simple: If you don't win, I don't win.
