Sean A. Montgomery, CFP®

CFO, Wealth Manager

Sean was born and raised in Arcadia, California. After high school, he left for Arizona to attend, and later graduate from, Arizona State University with a degree in finance. Sean worked for Bank of Hawaii right out of college in its U.S. Corporate Credit Department in Phoenix, Arizona. He then moved to Chicago to do the same for Wells Fargo while dating his eventual wife, Kelly, whom he met at ASU. Sean didn’t last long in the Midwest, as he quickly realized how much he enjoys sunshine and flip flops. He convinced Kelly to toss out the snow gear, and they headed back to the warmth of the Los Angeles area, where Sean began his career helping people to plan for and succeed in retirement.


Sean has been working with his clients for more than 20 years. Next to his name, you will see the letters CFP®, which stands for CERTIFIED FINANCIAL PLANNER. This means he has a passion for working with people who want to focus on getting their financial house in order, create a plan to meet their vision for retirement, and have someone work with them to see that plan through to the end. People’s lives are as dynamic as the world we live in—this is why Sean believes a working plan that takes into consideration all aspects of our financial lives is so important for financial success as well as peace of mind. This is at the heart of what he and the team at The Bridgeway Group do.

Outside of work, Sean and Kelly are kept busy raising their three energetic kids. Their children, Mckenzie (15), Parker (14), and Maddie (11), always have them running to soccer, basketball, flag football, or any number of other sporting events. Kelly works in the local school district as a 5th Grade teacher, a job that requires long hours and dedication to the needs of her students. When they get the opportunity to escape life’s daily routine, they enjoy camping, skiing, and visiting their timeshare in Princeville, Kauai.



Sean tries to stay active and keep up with Kelly, who frequently runs long-distance races. He loves to play basketball, soccer, and golf and regularly goes to the gym. He doesn't particularly like the gym; in fact, the 30 minutes he spends on the treadmill are the longest 30 minutes of his day. He has found, however, that his fondness for craft beer leaves him little choice. Sean and Kelly graduated from ASU and are a Sundevil family. Despite the fact the Sundevils have broken his heart many times over the last 20+ years, he is still an avid ASU football fan.
