Archway Dental Partners: A Connecticut DSO Built on DACT

Most regional dental groups start with a single practice and a long memory. Archway Dental Partners is the modern face of one that has been compounding for more than half a century. Its clinical roots trace to a single Newtown, Connecticut office opened in 1971; today that lineage anchors what the group describes as Connecticut's largest dental support organization, now reaching across the state line into Westchester County, New York. For an investor, the interesting part is not the office count — it is the structure: a long-established dentist-partnership culture, re-platformed with private-equity growth capital, deliberately expanding inside one of the wealthiest dental corridors in the country.

Overview

Archway Dental Partners is a multi-specialty dental support organization (which the company prefers to call a dental partnership organization, or DPO) headquartered in Danbury, Connecticut.¹ Like other DSOs, Archway does not itself practice dentistry. It provides the non-clinical machinery — operations, recruitment, marketing, and back-office support — while licensed dentists retain clinical control and, in many cases, an ownership stake in their practices.²

Archway is the management platform built on top of Dental Associates of Connecticut (DACT), a dentist-owned group established in 1971.¹ When the Archway brand launched in January 2024, DACT continued operating under its own name alongside the newly acquired practices folded under the Archway banner.² That two-name architecture — a legacy clinical brand plus a corporate growth platform — is the structural feature an investor should understand before reading any number: DACT is the heritage and the talent pipeline, while Archway is the vehicle for acquisitions and geographic expansion.¹²

The group is multi-specialty by design. Its providers span general dentistry, pediatric dentistry, orthodontics, oral surgery, periodontics, and endodontics, and it operates dedicated pediatric outposts in New Milford and Danbury alongside stand-alone specialist practices.² By footprint Archway is a regional player rather than a national one — concentrated, for now, in Connecticut with a deliberate push into the New York suburbs.³

Footprint Analysis

Archway's network is best understood as a dense Connecticut core with an emerging New York extension. At the January 2024 launch, the group reported approximately 23 practices and about 70 providers, all within Connecticut.¹ Those practices cluster along the state's most affluent demographic corridors — the Greater Hartford area (West Hartford, New Britain, Manchester), the New Haven and shoreline region (North Haven, Guilford), and the southwestern Fairfield County belt (Norwalk, Stratford, Bridgeport), with the Danbury headquarters anchoring the western part of the state.²³ That corridor concentration is strategically efficient: it lets a regional group share specialist coverage, recruiting, and marketing spend across a compact, high-value geography rather than spreading thin.³

From that base the company has grown steadily through acquisition. Over 2024 and 2025, Archway's own newsroom documents a series of Connecticut additions — including practices in Manchester, Waterbury, Windsor Locks, Avon, Guilford, and New Britain — alongside stand-alone specialty practices such as an endodontics group.² Company "about" language across those releases describes the network climbing from roughly 23 practices toward 30-plus, with providers rising from about 70 to 100-plus.² In September 2025, Archway reported acquiring CT Dental Management, a five-practice group, a step it framed as cementing its position as Connecticut's largest dental support organization.²

The second leg of the footprint is New York. Archway describes its 2025 entry into New York — anchored in Scarsdale and Chappaqua in Westchester County — as its move into a "second state," followed by additional Westchester partnerships.² Third-party speaker materials suggest the combined Connecticut-plus-New York network has reached the mid-30s in practice count, though exact, current, independently audited figures are not published.³ Because the various counts come from company boilerplate and directory listings collected at different dates — and because "practices," "offices," and "locations" are not always defined consistently — these numbers are best read as approximate snapshots of a moving target rather than precise totals.²³

Growth History

Archway's story is a long clinical history with a short corporate one. The legacy group, Dental Associates of Connecticut, was founded in 1971 — by a general dentist and a periodontist, beginning with a single office in Newtown, Connecticut.¹² Over the following five decades DACT grew into a dentist-owned, multi-specialty partnership, with a notable growth phase beginning around 2017.² Adam Richichi joined the organization in 2016 to work with the partner doctors on its future direction, a tenure that set up the eventual platform launch.²

The inflection point came in 2023 and early 2024. DACT — then roughly a 20-location group — was named a Group Dentistry Now "Emerging Dental Groups to Watch" winner in 2023, signaling industry visibility.² In January 2024 the group launched Archway Dental Partners as a dedicated multi-specialty platform, simultaneously announcing a recapitalization led by Martis Capital and Din Ventures.¹² At launch the platform reported approximately 23 practices and about 70 providers.¹

From there the trajectory has been one of consistent regional roll-up: a steady cadence of Connecticut acquisitions through 2024 and 2025, the 2025 cross-border entry into New York, and the CT Dental Management acquisition that the company tied to its claim of being Connecticut's largest DSO.² The stated ambition, articulated at launch, is to become New England's leading dental partnership platform — a goal that implies expansion beyond the two states it currently operates in.¹

Competitive Landscape

Archway competes in two overlapping arenas: the local market for patients and dentists in Connecticut and lower New York, and the national market for practices that want a partner. In its home state, the company positions itself as the largest dental support organization in Connecticut, a claim that reflects its corridor density rather than national scale.² Its regional peers include other Northeast-focused groups and the local footprints of the national DSOs.

Against the national platforms, Archway is a meaningfully smaller, more concentrated operator. Generalist DSOs such as Heartland Dental, Aspen Dental, and Pacific Dental Services operate hundreds to well over a thousand locations across many states; mid-sized multi-brand groups like North American Dental Group and Dental Care Alliance span a dozen-plus states.³ Archway, by contrast, is a two-state regional group in the dozens-of-practices tier. Its closest structural analog is the dentist-partnership, equity-retention model associated with groups like MB2 Dental, which similarly emphasizes doctor ownership over a corporate-employee model.³

The practical implication for the competitive picture is that Archway is not trying to out-scale the national giants. It is trying to be the most attractive partner inside a specific, affluent, fragmented geography — a focused-density strategy rather than a national-breadth one.²³

Market Position

Archway occupies a recognizable and defensible niche: the regional consolidator backed by institutional capital, leading a wealthy and still-fragmented market. Three features define its position. First, the dentist-partnership model — providers retaining clinical autonomy and equity — is a genuine recruiting and retention advantage in a labor-tight industry, and it is central to the group's pitch.¹² Second, the Connecticut corridor concentration gives it operating leverage that a geographically scattered group of the same size would not have.³ Third, the Martis Capital and Din Ventures backing supplies the capital and the acquisition discipline to keep rolling up practices.¹

The honest counterweight is that much of the supporting data is company-reported and changes quickly. Practice counts vary by source and date, deal terms are undisclosed, and the New York expansion is recent enough that its durability is not yet established by a long track record.¹²³ None of that undercuts the core thesis — a credible, capitalized regional platform in a desirable market — but it does argue for treating specific figures as directional and watching whether the New England-wide ambition translates into a third and fourth state.

TMR Take: For operators: Archway's appeal is the partnership model — clinical autonomy and retained equity, with the administrative burden handled centrally. If you run a high-quality practice in Connecticut or the lower Hudson Valley, it is one of the more relevant regional partners to know. For vendors: This is a fast-moving, acquisitive regional account concentrated in a compact geography. Selling into the central platform in Danbury can reach a growing roster of practices at once, but expect a buyer that values fit with a doctor-led culture. For investors: Archway is a focused-density bet — a capitalized regional roll-up in an affluent, fragmented market with a recent cross-border move into New York. The thesis is sound; the open questions are the pace of integration, the durability of the New York push, and whether the New England-wide ambition materializes. Treat company-reported counts as directional.
