What Nani does
Nani, legally Nephrology Associates of Northern Illinois and Indiana P.C. and doing business as NANI, is a physician-owned specialty medical practice focused exclusively on kidney care. Founded in 1970 (firmographic data alternatively cites 1968) and headquartered at 120 W. 22nd Street in Oak Brook, Illinois, the practice describes itself as the nation's largest private nephrology group, operating a network of over 140 board-certified kidney specialists and advanced practice providers (251–500 total employees) across offices in the Chicago metropolitan area, Indianapolis, Fort Wayne, and, following a 2025 expansion, Northern New Jersey. The clinical scope spans the full kidney disease continuum: chronic kidney disease diagnosis and management, dialysis (in-center hemodialysis, home hemodialysis, and peritoneal dialysis), kidney transplant evaluation and post-transplant care, interventional and vascular access services (catheter placement, fistula maturation, angiography, angioplasty), resistant hypertension management, and Phase II–IV clinical research participation.
The practice operates a sales-led and direct-to-consumer go-to-market motion combining physician referrals, hospital affiliations, direct patient appointment requests via nephdocs.com and phone, and community outreach through National Kidney Foundation screening and Walk for Kidneys events. It offers both in-office and telehealth appointments and provides a MyChart patient portal. Care delivery is heavily embedded in an affiliated ecosystem of dialysis operators (DaVita, Fresenius Kidney Care, U.S. Renal Care), hospital systems, nursing homes, and surgical facilities such as Willow Springs Surgery Center, where ASDN-certified interventional nephrology is performed.
Revenue is not publicly disclosed. As a private professional corporation, NANI monetizes primarily through patient care services billed to insurance (it accepts most major insurance plans on a pay-as-you-go basis) and secondarily through clinical trial research grants and study participation fees. The organization also owns Tower Physician Solutions, a wholly owned subsidiary providing practice management and consulting services, and has integrated acquired groups such as SouthWest Nephrology Associates (founded 1977) into its network. Leadership includes CEO Brian O'Dea and Executive Vice President Dr. John Ducker.

Nani competitors and assessment
Company assessmentBroad incumbents
- DaVita: Major dialysis provider that is also one of NANI's largest partners. Overlaps as a broad incumbent in kidney care, with growing interest in owning nephrology physician groups that could compete with NANI directly.
- Fresenius Medical Care: Largest global dialysis provider and NANI partner. Comparable as a broad incumbent in kidney care with vertically integrated physician services strategies that intersect with NANI's referral-based model.
- U.S. Renal Care: PE-backed dialysis provider partnering with NANI. Comparable as a larger, well-capitalized incumbent whose strategy of bundling physician services could compete with NANI's specialty practice model.
- Renal Physicians Association: National professional association representing nephrology practitioners — comparable as a broad incumbent in the nephrology specialty operating environment that frames NANI's competitive context.
- American Society of Nephrology: Largest professional society for kidney physicians — comparable as a broad incumbent in nephrology that establishes clinical, educational, and certification standards relevant to NANI's specialist workforce.
Emerging players
- Strive Health: Tech-enabled, value-based kidney care platform managing CKD and ESRD populations for payers — comparable as an emerging player targeting the same kidney-care continuum with a different, capitated model.
Direct peers
- Nephrology Associates of Central Florida: Multi-office private nephrology group providing comprehensive kidney care across Central Florida, including dialysis vascular access — directly comparable as a regional private specialty practice.
- Dallas Nephrology Associates: Large multi-site private nephrology specialty group serving the Dallas-Fort Worth region with comprehensive CKD, dialysis, and transplant services — directly comparable in operating model to NANI's regional super-group structure.
- Kansas City Nephrology Associates: Established private nephrology group covering the Kansas City metro with CKD management, dialysis supervision, and transplant support — similar scale and service breadth to NANI's local offices.
- Colorado Kidney Care: Multi-physician private nephrology practice offering dialysis, transplant coordination, and vascular access in the Denver metro — comparable to NANI as a regional private specialty group with full-service renal offerings.
