National Hospitalist Director

An ambitious entrepreneur and executive, Dr. Jose Aguirre has built successful healthcare businesses from the ground up and strategically grown them to national scale. His skill at enhancing medical quality, developing loyal teams and optimizing revenue has revitalized programs for healthcare systems across the country and attracted high-quality investors who share his vision and drive.

Just two years out of his Internal Medicine residency, in 2007 Dr. Aguirre was practicing at Carson Tahoe Regional Medical Center in Carson City, Nevada, when the administration began searching for a management company to oversee its hospital medicine program.

As a physician, Dr. Aguirre had seen opportunities to improve efficiency and patient experience, and knew the transformative value of cultivating high clinician morale and loyalty through transparency and generous compensation. He submitted the winning proposal, founding Aguirre Healthcare.

Two years later, in 2009, Dr. Aguirre’s hands-on approach to management was generating the hospital’s desired results and his practice had grown from six clinicians to 15. When several hospitalists at 380-bed St. Mary’s Regional Medical Center in nearby Reno approached him about employment opportunities, he cold-contacted the Chief Executive Officer with a plan to revive the hospital medicine program and restore physician confidence in the hospital.

Aguirre Healthcare assumed the contract in May 2010, doubling the size of the practice. Dr. Aguirre’s effectiveness led St. Mary’s to name him Chief Medical Officer in 2012. During his tenure, the hospital’s Leapfrog safety and quality grade rose from D to A, inpatient length of stay decreased half a day and readmissions fell 20 percent—all resulting in significant cost savings for the hospital.

As his business grew, Dr. Aguirre focused on improving services for his patients and partners. Weary of complaints about outsourced billing companies, in 2010 he launched his own revenue cycle management entity and set the expectation that his billing staff would treat patients with the same courtesy as his clinicians.

By 2014, Aguirre Healthcare’s record of executing innovative strategies to achieve its partners’ goals had attracted national attention. A Utah-based practice hired Aguirre to turn around 20 struggling hospitalist programs. A long-term care management company partnered with him to provide Hospitalist services at a newly built facility associated with the University of Tennessee Medical Center. In California, Aguirre Healthcare took over a hospital medicine program in Redding, and contracted directly with a Medicaid managed care organization in Sacramento. The company now had more than 150 clinicians in four states, with annual turnover below six percent.

As his company grew, Dr. Aguirre sought a like-minded partner to strengthen its resilience. In May 2016, Aguirre Healthcare merged with physician-owned Island Medical Management (IMM), which served two million patients through a nationwide network of emergency, hospitalist and intensive care programs. In September of the same year, IMM merged with Maryland-based Emergency Medicine Associates to form Alteon Health, the country’s sixth largest provider of acute care physician services, backed by private equity firm New Mountain Capital.

As President of Hospital Medicine for Alteon, Dr. Aguirre oversaw more than 450 clinicians operating in 40 acute care facilities and nearly 100 long-term care programs in a dozen states. He had full profit and loss responsibility, with more than $110 million in annual revenue. Having achieved his goals for his original business, Dr. Aguirre left Alteon in 2020 to Join NES Health as the National Hospitalist Director.
