ABMG Family

Brianna Finchum

Director of Business Management

I found my love for numbers, and reconciliation, in high school where I took Accounting 1 & 2 and went on to work as a bank teller. From there, I went to work for a national homebuilder where I started as the receptionist and worked my way up to Financial Analyst. When the 2008 recession hit home builders, I moved onto a commercial builder as the Staff Accountant. In August 2014, I started working for ABMG and am grateful to be part of an amazing team. While I am not helping clients, I am spending time with my two daughters. I was born and raised in Southern CA and currently reside in sunny Oceanside, CA so you can usually find us at the beach. I love spending time with my family and reading a good book.

Allie Finchum

Tax Coordinator

I was born and raised in Southern California and moved to Florida in 2000. I eventually returned with an added member to our family in 2013. I began working in for ABMG because I had friends and family that worked for Larry. Once here, I was hooked! I love being the go-to person to help resolve tax issues or helping those who just need a little guidance with their return. I’ve been married to Shon for over 32 years. I have a daughter, Kiah, who was recently married and a son, Kamryn. On my off time, you might find me on my bike on the Pacific Coast Highway or on my paddle-board in the Carlsbad lagoon.

Lilian Andres

Senior Bookkeeper

(Hablo Español)

I am one of five siblings who grew up enjoying numbers and discovered the passion for accounting as early as seventh grade. My focus while in college was majoring in Accounting with a minor in Spanish. At the age of 20 years old I started as an intern and shortly after I joined the ABMG team. Within a year I was able to reassure that the accounting industry was the right decision for me. My objective is to use all available resources and my knowledge to give you peace of mind so you can concentrate on your day to day activities. Off duty, I enjoy the beach and I’m slowly starting to pick up running, reminiscing on those track and field days.

Amy Cerros

Senior Bookkeeper

I was born and raised in San Diego County and am married with 2 kids. My favorite place is being in the mountains, either hiking or biking. My next favorite place is being home with my family working in the garden or kitchen. I believe strongly in ‘mind over matter.’ If you think you can do it, you will find a way to do it. Balance, determination, and grit are essential components to getting the most enjoyment in life.

Before joining the ABMG, Inc. family in June 2015, I worked as an Office Manager and Controller at a commercial construction company. I love working with clients to get their business bookkeeping in order so they have the information they need to make good business decisions. There is much satisfaction in helping my clients, who are struggling with their bookkeeping, and taking that aspect of the business “off their plate,” so they can focus their time and energy into growing their business and making it successful.

Wendy Mortensen

I am a Southern California native growing up in the San Gabriel Valley. After graduating from Pasadena City College, I went to work in the family printing company. When that closed, I started my own business doing bookkeeping work for multiple companies. That moved into becoming a full-time office manager and bookkeeper for an international film production and distribution company. During my time there we produced the Academy Award-winning Movie “Narc.” Since leaving I have been working full-time in daily business management for shopping center owners and multiple medical professionals. When I am not working, I’m the best Aunt ever (that’s what the mug says) to my 9-year-old nephew and 6-year-old niece.

Brandy Albanese

Business Management Assistant

I was born and raised in San Diego County. I have over 15 + years of Customer Service and Office management experience as well as various other administrative support duties. I joined the ABMG family in February of 2021. I am enthusiastic about growing and gaining new skills. I enjoy reading books, camping with my family and bike rides on the beach.

Jill Knight

Senior Bookkeeper

Jill Knight joins ABMG, Inc with 20 years of accounting experience. A native of Southern California, Jill received her Bachelor’s Degree in Accounting and Business Management at San Diego State University. In 2010, Jill moved to New York and worked with various tech companies and with an accounting firm that specialized in adding accounting structure to recently seeded, swiftly growing companies (Food and Beverage industry and SAAS). In 2016, Jill returned to Southern California and worked with the same accounting firm, but this time helping movie producers and West Coast Food and Beverage companies. Jill loves adding the needed structure to companies as they grow, so they can soar. When Jill’s not working, she can be found outdoors with her dog, hiking at the beach, or camping.

Jane Shi

Senior Bookkeeper

I studied how earthquake waves travel through the earth at a young age and had a fun job ediitng for a scientific magazine called "Progress in Geophysics" for a couple of years. Maybe not a lot of people know exactly what geophysics is about, so I switched gears to crunch numbers for the last 20+ years in the financial industry and investment banking services. Happily married with two boys. Life has been good, and I am very grateful. From Long Island, New York, to San Diego, California, it's another journey for me. I love nature and am never tired of exploring interesting new places. I enjoy cultural dancing for fun, DIY arts and crafts... all because once someone told me that anyone could be an artist! I'm very detail-oriented and analytical. So hear I am, happily joining the ABMG Family in 2022.

Myranda Mager

Jr. Business Manager

I have always had a love of numbers and problem-solving. I came to ABMG with about 10 years of Customer Service experience and 7 years of experience Managing Businesses. I am excited each day to not only learn something new but to fix any problem that comes my way. I am thrilled to be with ABMG! I started in September of 2023. When I am not working hard, I am spending time with my Husband, probably trying to find yet another amazing restaurant ... we are total foodies. And of course, when we are home, we are loving on our beautiful Puppy Mia; she is 8 years old but will always be a puppy to me!

Lisa Troop

Jr. Bookkeeper

I am a second-generation San Diegan and currently enjoy living in Oceanside. When I’m not working, I enjoy solo road trips and camping and spend a lot of time on the California Central Coast. It’s truly my happy place! I have a niece and two nephews, and I love being the “fun aunt”. Early on I was inspired to pursue a career in retail management and enjoyed working with a variety of people, coaching my team, and driving results. I bring over 30 years of customer service to my role at ABMG and strive to exceed my client’s expectations. I have a passion for organization. I believe that outer order contributes to inner calm and that attention to detail makes all the difference. I feel fortunate to be a part of the ABMG team.
