History
1980s
Alliance Imaging, Inc. was founded in 1983 as a shared mobile Computed Tomography (CT) provider.
Shortly after the introduction of clinical Magnetic Resonance Imaging (MRI), Alliance Imaging purchased its first mobile MRI system. Two of the first MRI technologists in clinical practice in the United States were hired to operate the unit in southern California. Over the next few years, Alliance grew rapidly, expanding its MRI services into northern California, and then the central and eastern regions of the United States.
1990s
Alliance continued its rapid growth, purchasing additional imaging systems and making a series of 13 strategic acquisitions.
By the end of 1998, Alliance had acquired 250 mobile MRI systems and serviced clients nationwide – becoming the nation’s largest provider of mobile MRI services. In December 1998, Alliance became the first national provider of shared imaging services to receive accreditation from The Joint Commission.
In November 1999, an affiliate of Kohlberg, Kravis, Roberts & Company (KKR) acquired majority ownership of the company.
2001
Alliance made a public offering on the New York Stock Exchange under the symbol AIQ.
2003
Alliance adopted a new strategic plan focused on introducing Positron Emission Tomography/CT (PET/CT) technology and fixed-site imaging centers into its service lines.
2005
Alliance Imaging acquired PET Scans of America and ADC, strengthening the PET, PET/CT and fixed-site imaging center segments of the company’s business.
Alliance Oncology was formed, adding radiation therapy to Alliance’s evolving diversification and growth strategy. Used primarily to diagnose cancer, radiation therapy is a natural extension for Alliance as the leader in PET/CT. Alliance Oncology partners with hospitals and other healthcare providers to establish new cancer centers or upgrade existing facilities with advanced technologies.
2007
In April 2007, Oaktree Capital Management, LLC (Oaktree) and MTS Health Investors, LLC (MTS) purchased the majority of KKR’s shares in the company and together now own approximately 48% of the company’s common stock.
In late 2007, Alliance commenced its acquisition strategy, acquiring New England Health Imaging and Bethesda Regional Cancer Treatment Centers. These strengthen the fixed-site imaging center and radiation therapy segments of the company’s business.
2008
Five acquisitions followed in 2008, including six radiosurgery CyberKnife centers from Accuray; Medical Outsourcing Services (MOS), a mobile PET/CT provider; and Shared PET Imaging, a mobile and fixed-site PET/CT provider. These strengthen the radiation therapy business as well as Alliance’s position as the nation’s largest PET/CT provider.
2010
Three acquisitions have been completed in 2010. In April, Alliance acquired a majority interest of Radiology 24/7, a San Diego-based radiology professional services company providing subspecialty professional teleradiology interpretation services for MRI, PET/CT, CT, ultrasound, mammography, X-ray and other imaging modalities. In June, Alliance acquired Diagnostic Health Anchorage, a large multi-modality, fixed site center. In July, Alliance acquired Arkansas Cancer Center in Pine Bluff, Ark.
2011
This year, Alliance has completed two exciting acquisitions. The acquisition of 24/7 Radiology doubled the company’s professional services line, and the acquisition of US Radiosurgery dramatically expanded the oncology division’s nationwide footprint. This transaction added eight stereotactic radiosurgery centers in eight states, making Alliance Oncology a leading national provider of dedicated stereotactic radiosurgery services with 18 centers.
Today
With more than 1,000 hospital clients in 45 states, Alliance HealthCare Services is the nation’s largest provider of advanced outpatient diagnostic imaging services. The company focuses on MRI, PET/CT and CT through its Alliance Imaging division as well as the expansion of its radiation therapy business through its Alliance Oncology division.
Alliance operates 570 diagnostic imaging and radiation therapy systems. The Company is the nation’s largest provider of advanced diagnostic mobile imaging services and one of the leading operators of fixed-site imaging centers, with 135 locations across the country. Alliance also operates 37 radiation therapy centers, providing state-of-the-art treatment and care for cancer patients.
