Beloved SLO CA dentist dies of West Nile virus

Key Points:

• Dr. Michael Colleran, a San Luis Obispo dentist known for his humor, kindness, and dedication to family, died at 63 after a two-month battle with West Nile virus, one of 29 fatalities in California in 2026.
• Colleran contracted the mosquito-borne illness after visiting Anaheim, experiencing severe neurological symptoms and hospitalization before passing away in a long-term care facility in Los Angeles County.
• Despite a statewide spike in West Nile virus cases this year, San Luis Obispo County reported only one infection, and local health officials urge residents to take preventive measures against mosquito bites.
• Colleran built a respected dental practice in San Luis Obispo since 2001, focusing on painless treatment and continuous learning, while maintaining a light-hearted office atmosphere; the practice is now up for sale following an arson fire in 2024.
• The family has launched a GoFundMe campaign to help cover medical bills and business debts, with a celebration of life scheduled for November 14 in Atascadero; they emphasize faith and community support during this difficult time.
