Southwest Kidney Institute

What Southwest Kidney Institute does

Southwest Kidney Institute (SKI) is one of the largest nephrology groups in the United States, operating as a private, physician-owned specialty practice headquartered in Tempe, Arizona. The organization delivers comprehensive kidney disease management across the full care continuum — kidney function testing, chronic kidney disease (CKD) management across all stages, dialysis (in-center hemodialysis, home hemodialysis, peritoneal dialysis), vascular access procedures, and kidney transplant evaluation and post-transplant care — through 40+ (some sources cite 47) clinic locations spanning 30+ Arizona cities, staffed by 60+ board-certified, fellowship-trained nephrologists and approximately 70 total providers. Its wholly-owned subsidiary, SKI Vascular Center (Tempe and Peoria), pioneered percutaneous arteriovenous fistula creation in the ambulatory surgery center setting as the first US ASC to offer the FDA-approved Ellipsys Vascular Access System following its 2018 approval, with the program having completed nearly 100 procedures. SKI also operates an athenahealth-powered patient portal, telehealth services, and a clinical research program offering trial access to cutting-edge therapies.

The business model is fee-for-service clinical care reimbursed through Medicare, Medicaid, and commercial insurance, with patient co-pays layered on top; no pricing is publicly disclosed because medical services are billed through payer contracts. The go-to-market motion is sales-led within healthcare: patients access care by phone-scheduling at a desired SKI location or through the online Patient Portal, while referring physicians use a dedicated referral form and Clinical Information Center to channel patients into the network. SKI maintains hospital affiliations with Banner Boswell Medical Center, Dignity Health facilities, and John C. Lincoln Clinic, and is co-branded with Panoramic Health, suggesting an emerging broader platform affiliation. The integrated treatment model — co-located lab testing, imaging, on-site patient education, telehealth, and the SKI Vascular Center specialty arm — is positioned as the primary differentiator versus fragmented single-specialty competitors, though no financial data is publicly disclosed and the ownership structure appears to remain a professional medical partnership without identified venture, private equity, or corporate parent ownership.

Core offering

Southwest Kidney Institute (SKI) is one of the largest nephrology group practices in the United States, providing the full spectrum of kidney disease management from early diagnosis through dialysis and transplant care. Board-certified, fellowship-trained nephrologists deliver integrated care including kidney function testing, chronic kidney disease management, dialysis (hemodialysis, peritoneal, and home hemodialysis), kidney transplant care, and kidney biopsy across 40+ Arizona locations. The affiliated SKI Vascular Center specializes in minimally invasive vascular access procedures, including the Ellipsys Vascular Access System pioneered as the first ambulatory surgical center in the US to offer this FDA-approved technology.

Product overview

Southwest Kidney Institute (SKI) operates as one of the largest nephrology group practices in the United States, offering a unified platform of kidney care services rather than a modular software product. The core offering spans comprehensive nephrology care — from kidney function testing and chronic kidney disease management, through dialysis (hemodialysis, peritoneal dialysis, home hemodialysis) and kidney transplant care — delivered by 60+ board-certified, fellowship-trained physicians across 40+ Arizona locations. The portfolio includes specialized sub-brands: SKI Vascular Center (pioneering minimally invasive Ellipsys vascular access procedures), an Athenahealth-based Patient Portal for 24/7 patient record access, Telehealth for remote consultations, and an active Clinical Research Program. The SKI Team Portal supports internal physician operations. The various treatment services (dialysis, transplant, kidney biopsy, 50+ condition-specific treatments) are integrated under the single SKI brand, unified by shared providers, locations, and the athenahealth practice management platform.
