Melinda Landchild, MD, Addiction Medicine Fellowship Faculty

Melinda Landchild, MD

Clinician/Teacher

Vancouver has been my home for my entire life. Although I love to travel, I always come back here. The recipe for my home is one part family, two parts friends, two parts abundant natural resources, and one part progressive community spirit. 
I have been at FMSW over 10 years because of our dedication to patients, our excellent staff, and our adaption to changes in community needs.

To me, Family Medicine was an obvious choice. Where else could I help patients from young to old, cis to LGBTQQ, from all walks of life, and take care of the entire family? Families may be born or created of all shapes and sizes, but everyone deserves a long-term family physician to care for them. I treasure the connections and trust that I have with patients.

I practice running, but I must admit that I enjoy painting much more. I don’t go hiking as much as I used to when I was younger.

I like passing on our family values of compassion, responsibility, tolerance and humor. I am grateful for the blessings that my family receives.

I am an avid boardgame and card game player. If you get me started talking about games, you may not get out of that conversation quickly.

I believe in trying to understand each person’s story, and to accept them for who they are. I hope to help patients and their partners try to lead healthy lives. I feel lucky to have the privilege of caring for patients. Whether I am present at a delivery or visiting an elderly patient at his home, it is deeply satisfying work. It is also rewarding to work with resident physicians, both teaching and learning from them.
