The biggest difference that we noticed right away was that there were all these things that we could be taking advantage of.
We could be way more strategic with how we were filing, what strategies we had in place, and what things had been ruled on from a tax law perspective.
My favorite part about it is, at the highest level— because there are tiers that you can work with the team through— but at the highest level, you’re fully supported.
Your accounting is taken care of. All of your tax strategy is taken care of. Basically anything you would need on the back end, money-wise, you’re taken care of.
That even includes if an audit were to come up or something like that. You have support with all of that. Love it. So grateful.
I would wholeheartedly recommend Greg O’Brien and his entire team to any small business or mid-sized business owner looking for help.
We don’t have the resources, and often don’t have the budgets, to bring on staff full-time.
Honestly, Greg and his team have been the next best thing.
I’ve been a client since day one, and I’m just so proud of him, seeing him build this up.
Now he’s helping so many people— so many entrepreneurs, so many businesses, so many investors, so many individuals and companies. It’s been incredible.
I’ve been working with him and his team for, yeah, must be four years now. And I would say, if you’re an entrepreneur, you own businesses, or you’re a high earner and you have investments like real estate, working with Greg is an absolute no-brainer.
They’re forward-thinking.
They’re cutting-edge.
They’re leaders in the space.
I know personally, for me, they’ve saved me a lot of money, which has been able to add to my net worth.
I’ve saved way more than they’ve cost, or the investment in them.And it’s so worth it. So much so.I’ve recommended dozens of people to them.
I discovered them through some research on Google, actually.
I had just moved to Massachusetts, and I needed a Massachusetts accountant, somebody to come and partner with me.
I’ve been using them for about two years now.
They are great partners.
They really support me in my business, and I highly recommend them.
I feel they can support any industry with all their accounting and tax needs.
