What inspired you to choose medicine?

I grew up in Canada where there weren't very many doctors and not a lot of access.

Why did you choose your specialty?

I had a very strong relationship with my maternal grandmother, and I always enjoyed hanging out with elders.

What is your philosophy of care?

I believe that the patient's relationship with their physician should be a strong one, with someone they can trust -- it should be open. And it should be with someone they can have fun with, maybe crack a few jokes.

What do you like about Yakima?

I like Yakima's four seasons. Also, people here are very friendly, and they're easy to get along with.

What do you like to do outside of work?

I play many different musical instruments; guitar, bass guitar, drums, keyboard, violin, baritone horn. I also like to play with my kids, and I read a lot.

What inspired you to choose medicine? I have always loved science and have a drive to constantly learn new things and challenge myself. Combined with my desire to help individuals, I found medicine to be the perfect path.

Why did you choose your specialty? Building long-term relationships and taking care of patients throughout all stages of life is my passion. I love educating on disease-prevention, devising care plans with my patients' goals for their health in mind, and working with specialists to provide the best care.

What do you like about Yakima? I came here for medical school in 2009 and was surprised to find that I enjoyed the quiet, relaxed pace of life. Being so close to the mountains, there is easy access to great hiking and skiing. Also, I like the sense of community here.
