Marco was born in San Diego. He spent some of his younger years with his grandmother in Tijuana, Mexico. He comes from a very musical family and started playing the guitar at an early age. The reason he started playing bass was really that he was asked to join a local band who needed a bass player. He had to borrow a bass and learn how to play it in a hurry - and he sure did learn how to play it!!!!

Marco is perhaps mostly known for his work with a number of rock bands, such as Thin Lizzy, Blue Murder, Whitesnake and with artists such as Ted Nugent, Ozzy Osbourne, David Coverdale and John Sykes. Less known is the fact that he has worked with a lot of other types of musicians such as Al Jarreau, Michael Ruff, Edgar Winters, Scott Hendersson, Tower of Power and the Cranberries. Marco is living in Los Angeles. He can be seen most Tuesday nights at La Ve Lee Jazz Club, Studio City, LA with his band 'Mendoza, Heredia, Neto' (When he´s not touring that is...). On the personal side..... Marco has two sons, Marco and Aaron, and two daughters Eva and Faith. He married December 2, 2001.
