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 wooing 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 L.A. 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 15 years. Next to his name you will see the letters CFP®, which stand 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 and crazy Weimaraner, Lucy, whom Sean sometimes refers to as “Lucifer.” Their children, Mckenzie (11), Parker (9), and Maddie (6), 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 special education teacher, an often thankless 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 trys 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 being just north of 40 and having a 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 an avid ASU football fan.

Theresa M. Mahoney

CMO, Wealth Manager

Theresa is our CMO and wealth manager. Throughout the past nine years, Theresa has learned about all areas of the business and industry while obtaining her FINRA Series 6, 7, 63, and 66 securities registrations.

As their trusted partner, Theresa works with her clients in order to devise strategies to help them achieve their most important financial goals.

Theresa is married and has two dogs. She is an avid football fan of the USC Trojans and Philadelphia Eagles, and she runs a family fantasy football league every year.

Scott E. Miller


Scott brings more than three years of industry experience to The Bridgeway Group. In his role as paraplanner, Scott provides financial planning technical support to Matt and Theresa and assists with client service needs. Previously, Scott was an associate vice president at a registered investment advisory firm.


After growing up in Rancho Palos Verdes, California, Scott attended the University of Michigan, earning his bachelor's degree in economics and playing for the rugby team. Four cold winters later, he moved back to the West Coast to be closer to family and friends.  

Scott discovered his passion for wealth management early on, as it provided the perfect way to combine his desire to help people and his interest in capital markets. He set his focus on learning through various internships and mentors until he started working for a firm in Los Angeles after college. Scott is currently pursuing his CERTIFIED FINANCIAL PLANNER™ accreditation and is eager to help the firm's clients plan for their future financial success.

Scott currently lives in Santa Monica with his dog, Tugg. He enjoys golf, travel, trying new restaurants, and taking on life's next adventure. Scott is a big sports fan and loves watching football, baseball, and rugby. His favorite teams are the Los Angeles Lakers and the Michigan Wolverines.
