Dr. Lim has served as the Medical Director of Redwood Pulmonary Medical Associates since its inception, closely collaborating with her colleagues in the community and mentoring pulmonologists and sleep specialists completing their training. She developed separate interest and expertise in sleep medicine while at Sequoia Hospital, which previously hosted one of the earliest accredited sleep centers in the Bay Area, the Sequoia Hospital Sleep Disorders Center. Since August 2015, the sleep center moved into the offices of Redwood Pulmonary, and is now called the Sequoia Sleep Center at Redwood Pulmonary. Dr. Lim also oversees Redwood Sleep Center, the only accredited sleep center in Marin County, California.

Dr. Lim treats patients in both the hospital and office settings, and her medical practice encompasses Pulmonary, Critical Care, and Sleep Medicine. She is interested in the breadth of pulmonary disorders but brings her special expertise in lung cancer to the community. She performs bronchoscopy at Sequoia Hospital. She shares hospital critical care duties with other dedicated pulmonary and critical care specialists. Her sleep practice is composed of patients who suffer from obstructive sleep apnea, insomnia, restless legs, periodic limb movements, and narcolepsy. Along with her colleagues at Redwood Pulmonary, she embraces a multidisciplinary and collaborative approach to the management of sleep disorders, tailoring treatments to the individual in order to achieve the best possible outcome.
