I was 29 years old when I attended my first fundraising event. The guest of honor was a candidate for mayor of Los Angeles.  I volunteered to help at the event that was held at an upscale art gallery in downtown San Jose. All I had to do was sign in attendees and collect donations, nevertheless I was anxious and a little intimidated. I had never been to a fundraiser or an art gallery.

As a kid, I remember that my dad used to say that every man should own at least one suit and a sports coat with a pair of slacks, so I had something handy to wear. I wore a gray two-button business suit, light blue dress shirt with dark blue tie, and cordovan penny loafers. The reason I remember what I was wearing so clearly is because it was the only dress clothes I had other than a tweed sports coat and navy wool dress pants.

The gallery was long and narrow. Modern art paintings hung on the walls and interesting sculptures sat on pedestals. White linen tablecloths topped tall cocktail tables and a small bar was staffed by a man dressed in a tuxedo.

A jazz trio softly played soothing tunes as men in business suits and professionally dressed women deposited checks into pre-printed envelopes, ate from small china plates, and chatted with other guests. It was like watching a well-choreographed dance.

After about an hour, the trio stopped playing and the event’s host introduced politicians and other VIPS to polite applause from the 40 or so guests. A few speakers enthusiastically praised the candidate, the candidate made brief comments, and the whole affair was done. Less than 15 minutes later, the gallery was empty.

Coming from a working-class Mexican American family, the only receptions that I knew about before that evening were related to weddings. The evening starts with mariachis entertaining guests, then dinner is served followed with a night of dancing. After the dance, family and close friends go to the home of the bride’s and groom’s parents for a nightcap. They all return for menudo the next morning. Total time: about 24 hours.

So here I was at the art gallery, 29 years old with a college degree, and I had just witnessed something that was completely out of this world for me. I was intrigued with the rhythmic nature of the event and fascinated that everyone knew how it worked. Since then, I’ve attended hundreds of receptions, breakfast events, luncheons, dinners, and cocktail parties. It was on-the-job training on how to conduct myself on a professional stage.

I’ve learned that choice of attire, how you stand, sit, move about the room, and shake hands all send messages on your credibility as a professional. Nobody is watching, yet everybody is watching. The impression you make on others could be the difference in getting the dream job, earning a promotion, or landing that lucrative contract.

More Latinos than ever are graduating with college degrees. That’s a good thing. Armed with an education and a valuable piece of paper, we’re making inroads into the offices of corporate America, government, and education. Taking the next step into management is another proposition. According to the 2010 U.S. Census, just 8.5% of Latinos who work are in “management occupations.”

Most of those management positions are in the service industry. The percentage of government and education administrators is less than 7% and Google recently disclosed that only 3% of its workforce is Latino. I can’t imagine Google, or any other Silicon Valley tech firm, employing more than a handful of Latino managers.

So what does this mean?

Racial stereotypes play a major role in how managers look at their Latino employees. They expect us to be service employees, blue-collar workers, domestic help, landscapers, construction workers, and so on. Latinos may not even register with executives when developing a management team. But we can’t let these facts keep us out of the executive suite.

Unfortunately, many of us lack the confidence it takes to be considered for advancement. School systems don’t teach critically important skills like confidence, poise, and how to conduct oneself in a professional setting. For many working-class Latinos, our first job out of college is our initial exposure to the white-collar world. While we’re educationally prepared for the work, we don’t understand the subtle protocols of advancing through large professional organizations.

So what do we do about this?

As a corporate executive, I’ve learned that those of us who have attained management positions need to actively seek out talented Latinos and mentor them on the nuances of “climbing the corporate ladder.” Leadership programs focused on Latinos in business and education are popping up across the country. As a professional community we need to support these efforts.

Professional Latinos also need to share their time and wisdom at school career days. Our kids shouldn’t have to wait for a college degree and a job before they learn how to dress, stand, sit, shake hands, and speak as a professional.

Latinos are smart, talented, and ambitious. More times than not, ugly racial stereotypes get in the way of advancement. That is what it is. We need to overcome those obstacles. Those of us who have been blessed to have experienced professional success are obligated to make sure that the next generation walks into that first art gallery reception with poise and confidence.
