US pediatric clinic universe, mapped

Nearly 84% of US pediatric practice sites are independent offices. The chains are real, but the long tail is where the buyer signs.

The top ten chains

The ten largest US pediatric clinic chains, by site count.

Sorted by total US pediatric site footprint, not by pure-play status. Privia Health has the largest raw site count because it is a platform that hosts pediatric practices across a broader multi-specialty network; Pediatric Associates is the largest dedicated pediatric operator. The distinction matters when you are buying data for outreach. The full parent-and-brand breakdown sits in Chain-by-chain below.

Who buys this data

Pediatric EHR vendors, vaccine distributors, and RCM firms selling into ~31,400 practice sites.

This page is for the teams selling into pediatrics, not the pediatricians themselves. Office Practicum, PCC, Sanofi Pasteur pediatric reps, McKesson and Henry Schein vaccine distribution, and pediatric-specialized RCMs are the buyers for this dataset. The buyer for this data usually falls into one of these categories.

Services

Pediatric billing services

Outsourced RCM firms with a vaccine-billing competency. Vaccines for Children, immunization administration codes, and pediatric well-visit coding are a different model from adult primary care, and the billing buyer knows it.

Supply

Vaccine and pediatric supply

Sanofi, Merck, Pfizer pediatric direct sales. McKesson and Henry Schein supply reps. The buyer is the practice owner or office manager who places the vaccine order, not a chain procurement office.

RCM

Revenue-cycle management

Athenahealth, Tebra, Waystar, and pediatric-specialized RCMs selling claim-scrubbing and denials management. Pediatrics has a denials profile that adult-care RCMs systematically misprice.

Platforms

Pediatric population health

Care-coordination, behavioral-health-integration, and value-based-care platforms targeting practices contracted under Medicaid Managed Care. The buyer is the medical director, not the chain.

Devices

Pediatric medical-device

Audiometers, vision screeners, pulse oximeters, infant scales, autism screening tools. Practice-level decision-maker, not group purchasing organization. Many sites still buy off a fax catalog, which says everything about the gap.

Adjacent universes built the same way: the owner-level pediatrician email list for direct outreach into the long tail, the by-industry email lists, and the rest of the Orbital data hub.

The long version

Detail, on demand.

Most published pediatric chain rankings sit inside a multi-specialty list or a private-equity tracker. They are accurate the day they ship and stale by month two. Our universe is drawn from the Orbital data team's primary and general care coverage, then filtered to practices where pediatrics is the dominant clinical specialty. For the full site-level dataset, see the companion pediatrician email list.

How the chain ranking is built

  • Start with every active US primary-care site. The Orbital data team's primary-care coverage spans solo pediatricians, pediatric group practices, family-medicine offices, and internal-medicine offices. We then filter to sites whose dominant book of business is pediatrics, using NPI taxonomy 208000000X and its subspecialties as the anchor.
  • Calibrate the independent-versus-chain ratio. We separate site-level affiliations from clinician-level rosters. We are practice-level: we surface the practice, the address, and the owner who signs the vendor contract, not the headcount of attributed physicians.
  • Resolve chain affiliations at the site level. Privia Health pediatric practices are tagged as platform-affiliated rather than parent-owned. Pediatrix office-based pediatrics is reflected after recent divestitures. Pediatric Associates Family of Companies sites, including Children's Medical Group, Allied Pediatrics, and Genova Pediatrics, are rolled up under the parent.
  • Find the owner. Around 84 percent of pediatric practice sites are independent or small group. Most managing partners are not on LinkedIn under a pediatric title. We find them by name, with a verified email and a direct dial, the same way we do for every other long-tail vertical.
  • Refresh on a rolling schedule. PE roll-ups, hospital acquisitions, and small-group closures land in the dataset inside the cycle. What you query in June is not what shipped in January.

Vendors targeting independent pediatric practices directly can also pull the broader pediatrician email list for owner-level outreach into the long tail. If you want the source breakdown for a specific state, chain, or EHR cohort, ask. We do not hide the working.

Ranked by dedicated pediatric clinic locations. The parent column carries the nuance most rankings miss: Privia Health has more raw pediatric sites but operates as a platform, not an owner; Pediatric Associates is the largest pure-play pediatric operator. That distinction matters for vendor targeting. The chain corporate office is almost never the check-signer for an EHR, a billing service, or a vaccine supply contract.

California, Texas, New York, Florida, and Pennsylvania carry about 38 percent of the universe. Per capita the picture flips: Massachusetts sits at 73 sites per 100,000 children under 18 against California's 39, because the Northeast preserved its independent pediatric practice base while the Sun Belt's growth happened inside health-system medical foundations.

We believe

If you sell into pediatrics and you only target the chains, you walked past about 26,500 buyers.

The standard PE narrative says pediatrics is consolidating fast. The math says otherwise. Our practice-level count shows the top 10 chains hold roughly 5.2 percent of US pediatric clinic locations. Dental got to 16 percent DSO penetration over fifteen years. Veterinary reached about 25 percent corporate ownership. Pediatrics is sitting at a fifth of that, and the structural reasons are real: Medicaid mix, vaccine economics, and the field's bright-line preference for independent practice ownership.

One operator called us last quarter. She runs a four-site pediatric group in central Ohio. She had not been contacted by her EHR vendor, her vaccine distributor, or her billing service in eleven months. Every demo her practice administrator booked, she had to source herself. That is the market most vendors are missing, not because the practices are hiding, but because the data tools are searching for Pediatric Associates instead of for the four-site LLC that signs the check.

Do not buy this if any of the following are true.

You only sell into children's hospitals. If your motion is one annual contract with Boston Children's, Cincinnati Children's, and Texas Children's, you do not need ~31,400 records. You need a handful of phone numbers in academic medical center procurement. Save your budget.

You need claims data or clinical outcomes. Specialty claims-feed licensors do that. We map the practices and the owners, not the diagnosis-by-diagnosis encounter file.

Your product is for parents. Telehealth apps, vaccine reminder consumer products, and parent-finder tools sit on the patient side. The data here is operator-side, organized around the practice that signs the vendor contract.

If you Google “largest pediatric clinic chains in the US,” the top result is usually a private-equity tracker or an industry list that ranks by attributed physicians. That is the right number for a payer doing network adequacy. It is not the right number for a vendor doing outbound. A practice with twelve attributed pediatricians inside a multi-specialty group like Privia is one buyer with one decision-maker. A practice with twelve dedicated pediatric clinic sites is twelve buyers with twelve managing partners. The first ranking counts heads. The second counts checks.

The next problem is freshness. Industry rankings tend to be organized by clinician, so when Pediatric Associates absorbs Allied Pediatrics or Children's Medical Group, the published files show individual pediatricians moving practices but the practice-level ownership change shows up in a footnote, six months later. Office-pediatrics footprints trimmed by divestitures over the last five years take quarters to flow through, and the version most vendors are working off is already stale.

This is the gap we built for. We map the universe of US small and mid-market businesses, find the owner of each one, and validate the contact before it reaches you. What is specific to pediatrics is the layer on top: NPI taxonomy, vaccine ordering pattern, payer mix, and whether the practice is independent, hospital-affiliated, or part of a PE-backed roll-up.

Vendors cite trackers that cite the filings. By the time the number lands in your pipeline, it has been quoted three times and refreshed zero. For a vendor doing outbound this quarter, the question is which practices are open this Monday and which managing partner answers the phone. The companion pediatrician email list goes deeper on the individual-contact layer.

Questions

Before you ask sales about pediatric clinic chains data.

How many pediatric clinic chains are there in the US?

Defining a chain as a pediatric group operating five or more clinic locations, there are roughly 140 pediatric clinic chains in the US. Together they account for about 4,900 of the country's approximately 31,400 pediatric practice locations. The remaining 26,500 sites are independent solo pediatricians and small two-to-four-physician groups that each sign their own vendor contracts.

Who is the largest pediatric clinic chain in the US?

Pediatric Associates, headquartered in Plantation, Florida and backed by a consortium led by TPG, is the largest pure-play pediatric group in the US with around 240 clinic locations across nine states. Privia Health's pediatric network has more attributed sites but spans multi-specialty practices rather than dedicated pediatric clinics, so the answer depends on whether you count platform-affiliated practices or only pure-play operators.

How concentrated is the US pediatric clinic market?

It is one of the least consolidated specialties in US healthcare. Defining concentration as the share held by the top 10 operators, pediatrics sits well below dental (where DSOs hold roughly 16 percent of practices) and veterinary (roughly 25 percent corporate ownership). The structural reasons are persistent: heavy Medicaid mix, vaccine economics, and a profession that has historically preferred independent ownership over employment.

Are pediatric clinic chains the same as multi-specialty groups?

No. A pediatric clinic chain is a multi-site organization where the dominant clinical focus is pediatrics. A multi-specialty group like Privia or Sutter contains pediatric clinics inside a wider footprint of family medicine, internal medicine, OB-GYN, and other specialties. For vendor targeting, the distinction matters. A pediatric EHR vendor cares about practices where pediatrics is the model. A revenue-cycle vendor often does not.

Who buys pediatric clinic chains data?

Vendors selling into pediatrics. Pediatric EHR vendors like Office Practicum and PCC. Pediatric-specific billing services and revenue-cycle firms. Vaccine and pediatric supply distributors like Sanofi, Merck, McKesson, and Henry Schein. Pediatric population-health and care-coordination platforms. Pediatric medical-device manufacturers. The common thread is they need the practice owner or managing partner, not just the chain corporate office.

Can I filter the pediatric dataset by state or EHR?

Yes. The dataset supports filters by state, metro area, parent network or chain affiliation, physician headcount, current EHR where known, and whether the practice is independent, PE-backed, or part of a hospital-affiliated medical group. Tell us the cut you want and the sample reflects it.

When is this dataset the wrong fit?

Three situations. If your product is consumer-side and you are trying to reach parents directly, this is operator-side data. If you only sell into hospital pediatrics departments, you want academic medical centers and children's hospitals, which we do not focus on here. If you need clinical outcome data or claims data, that belongs with specialty vendors who license claims feeds, not with us.

How is your pediatric data different from the AAP membership directory?

Clinician membership directories are organized by individual pediatrician. Our dataset is organized by practice location and surfaces the owner, managing partner, or administrator who actually signs the vendor contract. We refresh on a rolling monthly schedule against the universe of US small businesses, so closures, mergers, and PE roll-ups land in the dataset within the cycle, not the following year.

See the pediatric practice owner dataset before you pay for it.

Tell us the states, EHR cohort, or chain affiliations you want. We send a free sample of around 100 verified managing-partner records you can check against your own pipeline, no commitment, no email-list back-and-forth. For independent-practice outreach at the individual-contact level, see the companion pediatrician email list.
