Molina Healthcare Headquarters Address, Corporate Office Location, and Contact Details

About

Molina Healthcare, Inc. is an American publicly traded Fortune 500 managed care organization headquartered at 200 Oceangate, Suite 100, Long Beach, California 90802 — the same Southern California city where founder Dr. C. David Molina opened the first Molina Medical clinic in 1980 to serve low-income Medicaid patients being turned away by mainstream providers. Molina was founded in 1980 by Dr. C. David Molina — an emergency room physician in Long Beach who started the company with personal savings and a small loan — and has since grown from a single community clinic into one of the largest government-sponsored managed care organizations in the United States, going public on NYSE in 2003. The company is traded on NYSE under the ticker MOH and is exclusively focused on Medicaid, Medicare, and ACA Marketplace health plans across 19 states.

Molina Healthcare serves approximately 5.6 million members across 19 states — including Arizona, California, Florida, Idaho, Illinois, Kentucky, Massachusetts, Michigan, Mississippi, Nevada, New Mexico, New York, Ohio, South Carolina, Texas, Utah, Virginia, Washington, and Wisconsin — generating $45.4 billion in revenue for fiscal year 2025, a 11.75% year-over-year increase. The company’s four revenue segments are Medicaid ($30.6B in 2024), Medicare ($5.5B), Marketplace ($2.5B), and Other, with Medicaid forming the dominant share of its business. Joseph Zubretsky serves as President and CEO since 2017, having led a major corporate turnaround that transformed Molina from a financially distressed organization into a Fortune 500 managed care powerhouse.

About the Long Beach HQ and Molina Healthcare’s California legacy: Molina Healthcare’s 200 Oceangate headquarters in Long Beach — a coastal Southern California city in Los Angeles County — anchors a $45 billion managed care enterprise that has never strayed from the founding mission Dr. C. David Molina established in 1980: delivering quality healthcare to financially vulnerable families enrolled in government programs like Medi-Cal. The 2017 corporate turnaround — in which the board removed the founder’s sons from leadership and installed professional CEO Joseph Zubretsky — marked one of the most consequential governance decisions in the company’s history, transforming Molina from a financially challenged family-run organization into a disciplined, acquisitive managed care giant that more than quadrupled its revenue over the following eight years. Molina’s 2020–2022 acquisition spree — including Magellan Complete Care, Affinity Health Plan, Cigna’s Texas Medicaid contracts, and My Choice Wisconsin — rapidly scaled its Medicaid and Medicare footprint, positioning the Long Beach-headquartered company as one of the nation’s top three pure-play government health plan operators.
