Doeren Mayhew Makes a Florida Power Play with Lancaster & Reed Deal

Doeren Mayhew is quietly building a national footprint, and Florida is clearly on the map. The Top 50 firm just acquired Lancaster & Reed in Key Biscayne. This is not a random add on. It is a deliberate move into one of the fastest growing business markets in the country.

Why Florida and Why Now

Based in Troy, Michigan, Doeren Mayhew has been steadily expanding through acquisitions. The Lancaster & Reed deal pushes that strategy further south, placing the firm directly in the Miami area. Deal terms were not disclosed, which is typical in accounting firm transactions.

Florida checks every box firms care about right now. Inbound wealth. Privately held businesses. Cross border tax complexity. A steady flow of entrepreneurs and high net worth individuals relocating from other states. By buying a local firm instead of building from scratch, Doeren Mayhew gets instant market credibility and a team that already understands the landscape.

This is less about opening an office and more about building density in a high value region.

What Lancaster & Reed Adds

Public details on Lancaster & Reed’s size and niche mix are limited, but the strategic fit is clear. The firm serves clients that align with Doeren Mayhew’s core focus on closely held businesses and affluent individuals.

Lancaster & Reed’s Key Biscayne team now plugs into a broader tax, audit, and advisory platform. That gives existing clients access to deeper technical resources while keeping local relationships intact.

What Clients Should Expect

For Lancaster & Reed clients, this should feel more like an expansion than a disruption. Relationships are likely to stay in place, but service conversations will widen. Expect more discussions around multi state tax, advisory work, and specialized planning as the combined firm looks to standardize offerings over the next year or so.

Branding and leadership details were not fully disclosed, so how visible the change is day to day remains to be seen.

Another Step in a Bigger Roll Up Strategy

This deal fits a clear pattern. Doeren Mayhew has been adding firms and offices across multiple regions, including Tennessee, West Michigan, and Houston. The details of each deal vary, but the playbook is consistent. Acquire established local firms. Integrate them into a larger platform. Expand services without waiting years for organic growth.

This is becoming the default model in mid market accounting. Senior partners want succession options. Staff want bigger firm resources. Buyers want growth without greenfield risk. Doeren Mayhew is firmly on the buying side of that equation.

What This Signals

Two takeaways stand out. Florida is no longer optional for firms with national ambitions. And consolidation in mid market accounting is accelerating, especially in high growth states.

If you run a firm in Florida, expect more inbound calls from buyers. If you are a business owner, expect larger firms to show up with broader service menus. And if you are watching the accounting industry, Doeren Mayhew is clearly positioning itself as a long term consolidator, not a takeover target.
