US pediatric clinic universe, mapped
Largest pediatric clinic chains in the US (2026): top 10 hold 5.2% of about 31,400 locations.
For pediatric EHR, billing, vaccine-supply, and RCM teams selling into pediatrics. The chain logo on the door is rarely the buyer. The managing partner in the back office is.
The market, in three numbers
Pediatrics is the long tail, with a thin layer of chains on top.
of sites are independent or small group
About 84 percent of US pediatric practice locations are solo offices or two-to-four-physician groups. Not a chain. Not a hospital-employed clinic. A practice owner who personally signs the EHR contract.
share held by the top ten chains
Pediatric Associates, Privia Health pediatrics, Pediatrix, Sutter Pediatrics, Children's Medical Group, and the rest of the top ten run roughly 1,640 of the 31,400 US pediatric clinic sites combined.

Methodology
Why our chain ranking moves and the published lists do not.
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 classifier market "Primary and General Care" and then filtered to practices where pediatrics is the dominant clinical specialty.
How the chain ranking is built
- Start with every active US primary-care site. The Orbital "Primary and General Care" classifier covers 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. The Orbital classifier separates 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.
- 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.
If you want the source breakdown for a specific state, chain, or EHR cohort, ask. We do not hide the working.
By state
Where US pediatric clinics actually are.
The five largest states carry about 38 percent of the universe. Per capita the picture flips a little: states with younger demographics like Utah and Texas sit higher per 100k children than the older-skewing Northeast.

The top ten chains
The largest pediatric clinic chains, ranked by US site count.
Orbital's "Primary and General Care" classifier defines the universe of about 31,400 pediatric practice sites and anchors the chain ranking below. All numbers marked approximate.
| # | Chain | US sites | Parent / note |
|---|---|---|---|
| 1 | Pediatric Associates Family of Companies | ~240 | Plantation, FL. PE-backed (TPG-led consortium acquired 2021). Operates across nine states under Pediatric Associates, Children's Medical Group, Allied Pediatrics, and Genova Pediatrics banners. Approximate, June 2026 snapshot. |
| 2 | Privia Health pediatric network | ~310 | Arlington, VA. The pediatric site count sits inside a much larger multi-specialty footprint. These are pediatric practices on the Privia platform rather than dedicated pediatric clinics owned by the parent. Approximate, June 2026 snapshot. |
| 3 | Pediatrix Medical Group | ~200 | Sunrise, FL. Heavy on hospital-based neonatal and maternal-fetal medicine. The office-based pediatrics footprint has been trimmed by divestitures over the last five years. Approximate, June 2026 snapshot. |
| 4 | Sutter Pediatrics | ~180 | Sacramento, CA. Non-profit, integrated under Sutter Health and Palo Alto Medical Foundation. Pediatric sites sit inside a multi-specialty medical foundation rather than as standalone clinics. Approximate, June 2026 snapshot. |
| 5 | Children's Medical Group | ~130 | New York Hudson Valley. Now affiliated under the Pediatric Associates Family of Companies umbrella but historically operated independently. Approximate, June 2026 snapshot. |
| 6 | Allied Pediatrics of New York | ~120 | Albany, NY region. Joined the Pediatric Associates Family of Companies in 2022. Strong Upstate New York footprint with embedded school-health programs. Approximate, June 2026 snapshot. |
| 7 | Premier Medical Group pediatric division | ~90 | Multiple regional operators carry the Premier Medical Group banner. The pediatric line is concentrated in Tennessee and the Hudson Valley. Approximate, June 2026 snapshot. |
| 8 | IntegratedCare pediatric clinics | ~140 | Privately held multi-state pediatric MSO. Roll-up strategy focused on Sun Belt secondary metros. Approximate, June 2026 snapshot. |
| 9 | HealthDrive pediatric services | ~110 | Framingham, MA. Mobile and in-facility pediatric and adolescent services across multiple states. Site count counts active service locations rather than fixed clinics. Approximate, June 2026 snapshot. |
| 10 | ChenMed pediatric extension | ~120 | Miami, FL. Primarily a senior-care operator. The pediatric extension is regional and limited but counted here for the multi-site dedicated-clinic footprint. Approximate, June 2026 snapshot. |
Counts marked "~" are approximate, drawn from the Orbital site map. The order above is by US footprint of dedicated pediatric clinic locations. Privia's count includes pediatric practices on its platform rather than parent-owned clinics. The buyer for your EHR, your billing service, or your supply contract is the practice managing partner, not the parent holdco.

Our take
Pediatrics is the most under-consolidated specialty in US healthcare.
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. The Orbital classifier puts the share of pediatric sites in solo or small-group settings well above half, and 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 got to 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.

Plain-spoken
When the pediatric clinic chains dataset is the wrong fit.
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.
The honest version
Why most pediatric clinic chains vendor data is wrong.
If you Google "largest pediatric clinic chains in the US," the top result is usually a private-equity tracker or a Definitive Healthcare excerpt 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. Public filings are precise about attributed pediatricians but do not enumerate locations. Office-pediatrics footprints that have been 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 exactly 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. Nothing about that is pediatrics-specific, which is why we can also map dentists, HVAC contractors, med spas, restaurants, and auto dealers the same way. 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 private-equity-backed roll-up.
One more piece of context worth pricing in. 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. That is the gap a site-by-site, owner-by-owner map closes. The same shape we use for our pediatric work shows up in our broader /data insights coverage and in adjacent operator universes.
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.
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, embedded in its broader medical group, has more attributed pediatricians but spans multi-specialty practices rather than dedicated pediatric clinics.
How concentrated is the US pediatric clinic market?
It is one of the least consolidated specialties in US healthcare. The top 10 pediatric clinic chains hold roughly 5.2 percent of the approximately 31,400 US pediatric practice locations. Orbital's site-level view shows the majority of practicing pediatricians still work in solo or small-group settings, which is why most vendor outreach into pediatrics ends up at independent practices, not chains.
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. 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 monthly 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.
