(CNN) -- When the 2,455th star on the Hollywood Walk of Fame is laid on Monday for actor Steve Guttenberg, Ana Martinez will once again be working behind the scenes as curator-in-chief to the iconic attraction.





The Walk of Fame is one of showbiz's most visible landmarks,and Martinez has been its inconspicuous producer for almost half the attraction's 51 years, making sure the constellation of stars is perfectly aligned on the Hollywood sidewalks.





For 24 years, she has been the person deciding where celebrities will receive their coveted symbol of fame in the heart of Tinseltown. When a star is unveiled to the international press corps, Martinez is the field marshal orchestrating every detail of one of showbiz's alpha moments.





"If there was one phrase to describe Ana, it would be mistress of ceremonies," said Sam Smith, the former chairman of the board for the Hollywood Chamber of Commerce. "She truly is a master of the ceremonies."





Martinez has produced 586 star ceremonies. On Monday, Martinez will be at the ready with clipboard and iPhone in hand, negotiating over an obstacle course that typically numbers 22 film crews with 39 people, 22 still photographers, eight wire photographers, three newspaper reporters, two radio reporters, two photographers from the Chamber of Commerce and sometimes a celebrity's personal photographer.





"She is a gatekeeper of the integrity of the Walk of Fame. At the same time she's responsible for promoting the Walk of Fame all around the world," said Smith.





A star is awarded after a lengthy process in which hundreds of nomination applications are sent to the Hollywood chamber, and then its Walk of Fame committee selects the winners, with the approval of the chamber's board of directors. The names also are submitted to the city of Los Angeles' Board of Public Works Department. The chamber requires a $30,000 "sponsorship fee," often paid by a studio, recording label or even a group of fans, chamber officials said.





Martinez also coordinates when her boss, the president of the Chamber of Commerce, and various political figures speak in honor of the star.





Los Angeles Mayor Antonio R. Villaraigosa recognizes the importance of the walk as a civic landmark. He said it is "a powerful magnet which brings people from around the world to Los Angeles."





"Ana Martinez and the Hollywood Chamber of Commerce have played a vital role cementing L.A.'s reputation as the creativity capital of the world," Villaraigosa said in a written statement to CNN.





It's clear that Martinez loves what she does.





Martinez, who is 5 feet 4 inches with shoulder-length brown hair, declined to give her age, but said she started her career at the chamber as a receptionist in her early 20s after a brief stint at CBS. She assisted the then-publicist in handling the Walk of Fame. The publicist left the chamber six months later and even though Martinez was the obvious person to fill the role, management initially hesitated.





"The other staff and management said I was too nice, too shy," Martinez said. But Martinez eventually evolved in a way many stars do. "I had to create a different persona for the (star) ceremonies," she said. "I have to control everything."





With her staple head-to-toe black regalia to her dark shades -- green or gray depending on how bright it is outside -- she definitely controls the event.





When singer Shakira received her star in November, fans turned out in full force. The emotional followers swelled to nearly a thousand and nearly spilled over barricades when they saw their idol. Martinez said she welcomes fans because it also is a big day for them, but she keeps a close eye on security.





When one enthusiastic Shakira fan jumped over a barrier to meet his idol, the no-nonsense show-runner sprang into action. "I grabbed his wrist, pushed him back and our security girl carried him out," Martinez said.





Then of course, there is the celebrity. Martinez often already knows each family member and friend
