We believe financial services should come with clear answers and real accessibility. At Preston Financial Group, one phone call is all it takes to get timely, straightforward support from a professional who understands your needs.
Reliable financial services from people you can actually reach.
Preston Financial Group was founded with a simple belief: businesses grow stronger with clear financial guidance and reliable accounting support.
From the beginning, we have focused on helping small businesses plan wisely, manage their finances effectively, and grow with confidence through professional accounting services, bookkeeping, tax planning, and payroll support. Having worked with businesses across many industries, the team understands what healthy expenses, cash flow, and profit margins should look like—making it easy to spot issues early and provide practical, informed guidance.
This hands-on approach, combined with a constant effort to find smarter, more efficient ways to save businesses money, is why many clients view us as their unofficial CFO and a trusted long-term partner in financial growth.

Accounting You Can Trust.
"I’ve been working with Mason at Preston Financial Group for a few years now, and at this point, I can’t imagine trusting anyone else with our taxes. Before him, I always felt a little in the dark—like I was constantly reacting to tax season instead of understanding what was going on. Mason changed that for us.
He’s incredibly patient. Explains things clearly without ever talking down to you, which I really value. Our situation isn’t the easiest—personal taxes, a business, a couple of rental properties in North DFW, and filing as an S-corp—but he’s been able to handle all of it with ease. Or at least, he makes it look easy. I know there’s a lot going on behind the scenes."
