About Martinelli Environmental Graphics

Founder and owner Jack Martinelli started Martinelli Environmental Graphics in 1989 after two decades of experience in the sign industry.

Over the next 29 years, Martinelli succeeded in bringing together talented designers, fabricators, and managers to work with designers, architects, and contractors. The dedication of our employees gives us the reputation for providing high-quality fabrication and service to our many clients from around Northern California and across the country.

Today, our company is a well-established, full-service, licensed-bonded architectural sign manufacturer and contractor.
