Lilian Lam

Lilian Lam, RN

RN Practice Manager

Read Bio

Lilian loves working in healthcare because it is both rewarding and fulfilling. But what keeps her (and what she is in love with) is that there are always changes keeping her engaged and on her toes. Being a nurse gives her a variety of different specialties and niches, so she’s been able to find what’s right for her personality type, and loves that if she wants to change her specialty one day, nursing is a field that gives her the flexibility to do just that. She’s happy to be in an industry full of selfless individuals, one that allows her to serve the community as well as develop professionally.

 

Lilian earned a BS in Health Science from California State University, East Bay, and an AS in Nursing from City College of San Francisco. Prior to her role as Practice Lead, she worked as the Nurse Manager/Office Manager at a pediatric primary care office in SF, where she developed a passion for working with and encouraging new parents. She also worked in a Med-Surg unit at a small community hospital in her hometown of Delano, California, which is where she got experience working on a code-blue team. Lilian also learned the value of having culturally competent providers, nurses, and support staff while she was in that role. All of her experiences have shaped her as a nurse, and helped her consider each unique path that the people she’s helping might be on—including patients, family members, or the staff she serves.

 

Outside of work, Lilian enjoys reading, hiking, cooking, and baking.

Why do I practice healthcare: Since childhood, I have had a keen interest in healthcare. I enjoy learning new things, patient relationships, and the ever-evolving nature of medicine.

I enjoy the collaborative efforts and camaraderie of our teams.

What makes me unique: I was very lucky to travel extensively when I was younger. Seeing people from all walks of life living so differently from myself (and each other) had a profound impact on me. I am open to looking at things in new ways and always willing to listen.

 

Why do I practice healthcare: I work in healthcare because I genuinely enjoy helping others, and I wanted a career that would allow me to continue learning over the course of my lifetime. I have been lucky enough to find both these qualities through a career in Chinese medicine.
