Andrew Kuo

Andrew Kuo

Managing Director Operations,
Information Technology, Transitions

Andrew’s first exposure to the investment industry came when he was working as a bank teller in college. A financial planner would come to the branch a couple of times a week and Andrew would always ask him about his opinions on the markets and what he thought was a good investment.

It was during this time that he realized that this was the industry he really wanted to be in.

Over the years, Andrew feels that he has been fortunate to work in several roles and learned from many great mentors about the different aspects of our business. Having been both an advisor as well as having worked in the back office has provided him with invaluable lessons on how to serve our customers. In 2007 Andrew joined Western and knew from the first day that he had found a place where he would be happy and would be able to grow and knew that his experience would help with the growth of a progressive firm like Western.

Andrew originally came on board as the Senior Compliance Officer and was then named the firm’s Chief Compliance Officer. At the beginning of 2009, he transitioned to Managing Director of Operations to oversee the teams including broker relations, insurance and information technology.

Andrew’s Bachelor of Arts degree is in business with an emphasis on International Business. He holds FINRA licenses 7, 24, 63 and 66. Outside of work, Andrew enjoys spending time with his family and being out on the golf course.
