A memorial service will be held Friday for Douglas Martin Rosoff, a Ukiah psychiatrist and avid bicyclist killed Friday when he collided with a dump truck.
Rosoff was 56. Police have yet to determine who was at fault in the Ukiah crash.
Employees at Mendocino County's mental health department, where Rosoff worked for 17 years, are reeling from the loss, said Jeanine Miller, a supervisor and psychologist with the department.
"He was an amazing man and he touched so many lives," she said.
Rosoff was Mendocino County's chief psychiatrist until he retired from that post last year. He most recently was working at the Ukiah Veterans Administration medical clinic. Rosoff also provided expert psychiatric testimony in court on occasion.
His former co-workers at the county remembered him Wednesday as compassionate, caring and smart. He was committed to his work and willing to make himself available in emergencies, they said.
"He was always available to everyone in the community," Miller said.
Cheri Heffel, a nurse practitioner at the Veterans Administration clinic who also had worked for years with Rosoff at the county, recalled him as "a humble, gentle, kind soul."
Rosoff also had a light side. Miller said a co-worker recalled Wednesday how overjoyed Rosoff was when he announced he was getting married six years ago.
"He was so excited. They danced together in his office," Miller said.
