Thirteen accounting firms have united to form
Operating in an alternative practice structure as Sorren CPAs PC for attest services and Sorren Inc. for business advisory and non-attest services, the combined firms have 85 partners and approximately $170 million in revenue, with plans to add more firms going forwards.
Many of the founding firms met as members of the BDO Alliance, and their leaders had gotten to know one another as attendees at alliance meetings and managing partner roundtables, according to Josh Tyree, the president of Sorren, who was previously president of Harris CPAs, an Idaho-based firm that was the first of the group to go the PE route, signing up with DFW in January 2024.
"Harris had started looking at that process with DFW for a good chunk of 2023," Tyree recalled, "and I remember we were having a managing partner roundtable meeting in Nashville that year in the fall, and they were all there and I raised my hand after two hours of talking about PE and I said, 'Hey guys, I think I'm going to jump in feet first and you guys should all come and join us.'"
And they did — with individual firms joining up with DFW over the course of 2024, and a large group in January 2025.
"There was a level of comfort," he explained. "We knew all of our firms and our people and what we do and how we do it because we'd shared so much information over the years."
Apart from Harris, the other firms currently comprising Sorren are:
- Acuity (Georgia);
- Aycock & Co. (Texas);
- Capital Nomics Valuations (California);
- Chigbrow Ryan Murata (Idaho);
- Hoerber Tillman & Co. (Florida);
- JRJBF (Illinois);
- KDP Advisors (Oregon);
- KMA Advisors (Wisconsin);
- Pisenti & Brinker (California);
- Roeser Accountancy (California).
- SBF Advisors (Florida);
- Stockman Kast Ryan & Co. (Colorado).
Allan Koltin, CEO of Koltin Consulting Group, said in a statement, "What makes Sorren stand out is the way these firms came together — with intention, shared values, and a commitment to staying deeply connected to their local markets. This group didn't just merge for size; they united around a common purpose. It's a blueprint for how innovative firms can grow, while staying true to who they are."
The firms all have a strong focus on small and middle-market businesses and nonprofits that want a local firm feel and relationship, even if they need services across the country. As it adds new firms, Sorren will prioritizing those that are a fit with their current culture.
"If we go into another region, we want to start with leadership and good people; we're not just randomly going out to try and find any firm that meets [a client need]," Tyree explained. "It really has to fit our culture and it has to have a leader in that area for us to go into that services."
He also made the point that Sorren is still very much a work in progress — relying on current firm expertise to build national practices in tax, assurance, CAS and advisory.
"One goal when we originally started was we wanted to get to enough mass size that we could really start to build this by using leadership from and talent from all the firms that came on board," Tyree said.
"It's going to be super fun, but it's a lot of work," he added. "If all you're looking to do is do a rollup or something like that, that's probably not our style. We're trying to create this for our type of client and our type of cultures. And we think there's a little void there where we can do it."
