Why I chose this program/location for my training

Muskegon is a great location with quick access to Lake Michigan and an abundance of outdoor activities. Additionally, it is only a short drive from Grand Rapids and Grand Haven for all my city needs.

What ultimately won me over, however, were the residents and attendings at the Fruitport Family Medicine clinic. Everyone was friendly, inviting and quite simply fun to be around. Everyone was eager to teach and it left a strong impression of being a great environment to train.

Hobbies/interests outside of work

Why I chose this program/location for my training

I chose Mercy Health because it honestly felt like family when I did my 4th year rotation here. The residents I worked with helped me feel like I was a part of the team. Whenever I struggled with something, they were always willing to help with the most sincere and genuine smile. Not only did I get along with my future co-residents, but the rest of the staff were also welcoming and this dynamic truly allowed me to grow and learn during my time there.

Hobbies/interests outside of work

Growing up in a Vietnamese family where all my meals were made from scratch, I grew to love cooking and making meals for myself and those I love because that's what my parents did for me. The end result of cooking, eating, is obviously a favorite hobby of mine as well, and I think the conversations that people make sitting around a dinner table can really deepen friendships and relationships.

I focus a lot on healthy meals and recipes and highlighting ingredients people normally don't think they can enjoy and enhance it for their experience. In conjunction to healthy meals, I also enjoy leading an active lifestyle whether it be biking, running, being outdoors or getting in a good active gym session. I believe being active and feeding your body good food are essentials for self-care, which is important at any point in your life!
