ABOUT KERRI & TREVOR
Hello! I’m Kerri Gardner, a Certified QuickBooks Online ProAdvisor and professional bookkeeper based in New Bedford, Massachusetts. While we are locally rooted, we use cloud-based technology to deliver QuickBooks Online bookkeeping services to businesses nationwide. My specialty lies in tackling the tough jobs—Deep Dive Clean Ups spanning months (or even years) of backlogged books and converting QuickBooks Desktop files into QuickBooks Online—so business owners can finally move forward with confidence and clarity.
For over three years, we've worked with businesses of all sizes to restore financial order, streamline their systems, and set them up for long-term success. Our mission is clear: to clean up and simplify your bookkeeping, provide the clarity you’ve been missing, and give you the tools you need to grow—all while reducing financial stress.
Originally from New England, I now reside in New Bedford, Massachusetts with my husband, Trevor, and our three amazing children. When I’m not partnering with business owners to transform messy books into organized systems, I enjoy nurturing my passion for gardening—a green thumb I’ve cultivated for over 29 years. You’ll also find me unwinding with a good book and a refreshing cocktail on my front porch or indulging in a movie marathon during my downtime.
Fun fact: I have a serious love for watermelon and can eat an entire one in a single sitting!
If your books feel overwhelming—whether you’re facing months or years of backlog or need help moving from Desktop to QuickBooks Online—TreKer Bookkeeping is here to help. Let us take the stress off your plate so you can focus on growing your business.
Hi, I’m Trevor Gardner, a Certified QuickBooks Online ProAdvisor and professional bookkeeper based in New Bedford, Massachusetts.
Together with my wife, Kerri, we leverage cloud-based technology to provide seamless bookkeeping solutions to businesses nationwide. Our specialties include Deep Dive Clean Ups spanning months or years of financial backlog and QuickBooks Desktop to QuickBooks Online conversions—so business owners can finally gain the clarity, organization, and confidence they need to move forward.
Locally rooted yet nationally connected, we pride ourselves on simplifying financial management so business owners can stop stressing about their books and start focusing on growing their companies. For over three years, we’ve helped businesses of all sizes streamline their operations and achieve financial clarity through tailored QuickBooks strategies.
Originally from Gloucestershire, England, I now call New Bedford, Massachusetts home, where I live with my wife Kerri and our three wonderful children. When I’m not empowering business owners through efficient bookkeeping, I enjoy indulging in my hobbies. You’ll often find me playing the guitar, strategizing in Clash of Clans, or building intricate LEGO sets—a favorite pastime my family fuels with thoughtful gifts every birthday and Christmas.
Kerri and I share a long-standing passion for gardening, spending winters planning and prepping seeds for our spring garden. We also cherish quiet evenings and weekends on our front porch—Kerri enjoying a refreshing cocktail while I savor a pint of IPA or Guinness. After brewing my own beer for 15 years, I now frequent local breweries to enjoy their incredible ales.
Fun Fact: While Kerri is famous for devouring an entire watermelon in one sitting, I’m equally guilty of polishing off a bag (or two) of Cheetos Cheese Puffs—no judgment, please!
