About TSI
Founded in 1985, Telephone Sales & Installation, Inc. began in Fayetteville, a small town south of Atlanta. Founders Tim and Phil DeMarcus wanted to build a business that kept their community connected with reliable phone systems.
Later, Tim DeMarcus, Jr., would join the business and help it grow to service the entire metro Atlanta area.
With a passion for excellence unmatched by others in their field, the Telephone Sales & Installation team strives to keep businesses connected and secure through top-of-the-line landline phones and surveillance security systems.
