Why I chose this program/location for my training

I chose this program so that I could become a more well-rounded provider to better serve my community. I wanted the opportunity to continue to grow within a program designed for learning and additional mentorship as I start my career as a new graduate PA! I have loved all my rotations in the hospital setting thus far, so I am looking forward to getting experiences in a variety of new areas of medicine as well as narrowing down what specialty I want to eventually end up in.

I have been lucky enough to call West Michigan home for the last 7 years and the location was perfect for me and my goals of staying long term!

Hobbies/interests outside of work

I love the beach, hiking, running and traveling! I grew up camping every summer in state parks all over Michigan and love the outdoors. I also love to cook/bake and I'm always up for trying new recipes. I'm very close to my friends/family and spend a lot of my free time with them when I can!

Why I chose this program/location for my training

After finishing my PA degree at Western Michigan University, I wanted to pursue more training on the western side of Michigan because I loved the landscape and the people. Coming from a small town in Wyoming, I fell in love with exquisite beaches and hikes that Michigan had to offer.

I had heard many wonderful things about Trinity Health's PA residency program so I decided to pursue more training at that location. The programs mission and schedule for training PA resident fellows drew me in because I desired medical confidence and expert training within the Internal Medicine world.

Hobbies/interests outside of work

I enjoy being outside, eating delicious food and spending time with friends and family. My heart lives in nature and in its bountiful beauties. Going to the beach, hiking in the trees and dunes around Michigan, and when I go home, hiking in the mountains. I also enjoy the arts, including seeing plays, live music, art shows and concerts.

Why I chose this program/location for my training

Despite loving every rotation I went on clinical year, by the time I became a new grad, I still hadn't felt that I found my niche yet. With this program, I liked the idea of diving deeper into the areas of medicine I initially got exposure to in PA school, while also gaining experience in the areas I've never had the chance to work in. As someone who's passionate about teaching, I also liked the idea of receiving the extra mentorship and training that I could eventually pass on to others. The fact that this program is next to Lake Michigan, an area I've always wanted to live in, is definitely a bonus.

Hobbies/interests outside of work

Outside of work, I enjoy hiking, camping, cooking, and spending time with friends and family. I am definitely looking forward to exploring and learning more about the west side of the state!

Why I chose this program/location for my training

This program offers a unique opportunity for PAs to really strengthen their knowledge base in all areas of medicine.
