What Does it Mean to Be the "Most Reachable Firm?"

While it's a bit of a hyperbolic joke, we are serious about being available to our clients. With accounting firm mergers and acquisitions being so common, it's easy for businesses that were once a high priority to fall to the bottom of the list as a firm continues to grow. If you used to hear back from your accountant within a day, maybe that dropped to a week, a month, or worse. It can be frustrating to feel like your filing is getting done at the last minute, and the radio silence you receive from your contacts can make it feel like nobody cares.

As part of our commitment to being the most reachable firm, we promise to return messages from our clients within 24 hours on business days. Email is the best way to reach us so that we can gather more details before we respond. Your business is our priority.
