GRASS VALLEY, Calif. January 10, 2018 – Dr. Christina Lasich, a longtime resident, community leader and medical professional in Nevada County, has been promoted to Chief Medical Officer of Western Sierra Medical Clinic, the largest outpatient provider in Nevada and Sierra counties.

Dr. Lucas-Ross left the position to focus on her clinical practice. She will treat patients in Grass Valley and Penn Valley. Dr. Lucas-Ross will accept new family medicine patients, consult on more complex cases with colleagues, perform in-office procedures, and treat pain clinic patients.

“We are in an extremely fortunate position, where we have such a highly skilled and well-trained health care professional as Dr. Lasich who we can promote to the critically important position of Chief Medical Officer, while also enabling Dr. Lucas-Ross to return to treating patients full-time,” said Western Sierra CEO Scott McFarland. “I’m very appreciative of Dr. Lucas-Ross’ efforts and hard work, especially with our fast-paced growth during her tenure. I’m certain Dr. Lasich will continue to elevate the quality of care.”

“I’ve always appreciated Western Sierra’s wellness-centered approach to patient care, with a focus on getting to know the individual, their challenges and life situation in order to provide the most effective health care,” Dr. Lasich said. “I’m looking forward to directing the Western Sierra team and working closely with the health care community to improve the health of residents.”

Dr. Lucas Ross, who was raised in Grass Valley, earned her medical degree from the University of Nevada School of Medicine, Reno, and completed her Family Medicine residency at Sutter Health in Sacramento.

“I care about where I live, especially because I grew up here, and it’s a privilege to live and work in this community,” Dr. Lucas-Ross said.

Western Sierra – which provides comprehensive medical, dental and behavioral health care – has greatly expanded with new locations and services during the past few years. Western Sierra has added obstetrics-gynecology, an on-site pharmacy and opened an Urgent Care clinic for the public at the Grass Valley health centers.

In addition, Western Sierra has opened health centers in Auburn, Kings Beach-Tahoe and Penn Valley during the past two years. Urgent Care and maternity health services are also available at Western Sierra in Auburn.

“Drs. Lasich and Lucas-Ross have been leaders in our past success and will continue to play key roles in our future,” McFarland said.
