Our Founder

Adrian Acosta is the founder and owner of On Time Rooter and Plumbing. He is a licensed and certified plumber with more than 10 years of experience in the industry. His grandfather was a plumber too and he taught Adrian everything he knew when he started the company in 2018.

He wanted to create a company that people can trust, a system that could create jobs without having to rip off customers.
