Jeannine G. Vanian, 51, is chief operating officer of Kayne Anderson Rudnick, a boutique investment advisory firm in Los Angeles that manages nearly $24 billion in assets for institutional, broker-dealer and high-net-worth clients. The 29-year-old company has 90 employees.

Vanian was born to an Armenian family living in Addis Ababa, Ethiopia. Her father, Ghazar, who was an accountant, died when Vanian was just 11. Watching her mother, Hasmig, struggle to support three children formed a lifelong determination.

“I decided I was going to be an independent woman that could take care of herself and whoever else I needed to take care of, including, obviously, my mother,” Vanian said.

The kind of long hours that Vanian would later devote to her career began early as she held various jobs while earning a degree in business and executive management at the American University in Cairo.

By the time she earned her degree, some family members had moved to the U.S. Vanian decided to join them and wound up temping for Allan M. Rudnick while he was working as portfolio manager and chief investment officer for the Pilgrim Group. When he left to help start Kayne Anderson Rudnick, in 1984, he brought Vanian with him.

“I was there whenever needed,” Vanian said. “I remember long hours, weekends, trying to help build a business. I was lucky to have a mentor like Allan Rudnick, and the other two founders. They gave me the opportunity to try things out, to learn, to fail.”

Since coming on as an assistant, Vanian has been a portfolio administrator, director of portfolio administration and managing director. She has been chief operating officer since October 2005. When she took on more leadership responsibilities, her bosses were encouraging.

Vanian said her superiors always said, “ ‘You can do this, you’ve got this. We know you can. We’re confident in your abilities.’ “

Vanian said she has always shown that “I’m very passionate about the firm, and really believe in what we do here. Having the attitude of, we’ll do whatever it takes as a team, and really look at new opportunities as a new challenge, something to really learn from.”

As chief operating officer, Vanian is responsible for “the operations department, trading, marketing, accounting, client services, human resources.” She’s part of a three-person executive team that reports to the parent company’s chief executive.

Vanian has helped assemble a team unlike many in her industry. There are 22 languages represented by the company’s 92 employees. “We’re in finance, which is generally a male-dominated industry,” Vanian said, “and 41 percent of our employees are women, and 53 percent of our managers are women.

“My hunch is that we might see more women come through here than many other firms in our industry primarily because when they go to the website, they see that there is a strong presence here. They are attracted to that.”

Vanian and her husband, Craig, have been married for about 20 years, she said. They have three children. Traveling is a favored family activity. “We have been to, I think, 42 countries. The kids have been to between 20 and 25 countries. Exploring different cultures as much as we practically can is something that we love to do.”
