A Personal Commitment To Quality.

Mark’s Machine Co., Inc. was started by Mark Pratka. Mark graduated from Lamar University at the top of his class and gained several years of practical work experience in the petrochemical industry before starting up his own machining business in 1979. In 1980, Kay Pratka joined the team as Vice President to streamline the financial and office operations. Mark’s Machine became incorporated in 1982.

Mark’s Machine initially concentrated it’s efforts in the compressor valve repair business. Today, in addition to the full service compressor valve division, MMCI offers full service machining, manufacturing, and powder coating. Hard work and dedication to quality service has fueled steady growth at Mark’s Machine. As Mark’s Machine diversified its repair and manufacturing capabilities, the client base expanded as well. Today, Mark’s Machine is the vendor of choice for a growing number of petrochemical, oilfield, and offshore industries.
