Why I chose this program/location for my training

I rotated here during my 3rd and 4th year of medical school, and the relationship between the residents and attendings really stood out to me. It felt like a big family where everyone is so supportive of each other. Another reason I chose Muskegon is that it’s an unopposed program which means that the ER gets to do many procedures that would otherwise be given to surgery residents. I loved the community setting and the EM residents seemed well prepared after seeing such a wide variety of patients and pathology. Also, West Michigan is beautiful and being so close to Lake Michigan is definitely a plus!

Hobbies/interests outside of work

I love being on the water, whether it's on a boat or at the beach. I spend a lot of time outside with my dog and 2 horses. Other things I enjoy are baking, photography, and traveling.

Why I chose this program/location for my training

I chose Trinity Health Muskegon because of the people and the location. During my rotation here as a medical student, I felt welcomed and supported by the entire ED team. I appreciated how collaborative the environment was and how involved I was in patient care. That experience made it clear this was the kind of place I wanted to train.

I’m confident this program will give me the training and mentorship I need to become a well-rounded emergency physician.

Hobbies/interests outside of work

I enjoy hiking, hunting, boating, and spending time at the cabin - especially ending the day around a campfire with family and friends. Most of all, I enjoy being with my dog, Kona, a high-energy German Shorthair Pointer. She’s my sidekick, and we do just about everything together. If she’s happy, I’m happy.

Why I chose this program/location for my training

I was first drawn for the beach and proximity to my family, but I quickly realized how amazing Michigan is and why so many people never want to leave this state. Trinity Health Muskegon's Emergency Medicine program, in particular, offers exposure to such a wide variety of cases, since it serves much of the west side of the state. It also has outstanding and brilliant faculty and current residents who foster a very welcoming environment.

Hobbies/interests outside of work

I love playing in recreational volleyball leagues both indoor and beach. I also travel as frequently as possible most recently in the past year to Portugal, Greece, Germany and Switzerland.

Why I chose this program/location for my training

West Michigan is home for me. After rotating at the local EM programs, it became clear that Muskegon was where I belonged. I found the program to be superior in terms of resident knowledge, exposure to high acuity patients and procedures. Rather than being "integrated" into the trauma cases, I saw residents take the leading role which translated not only into confidence in the protocols but also an ability to think critically and work beyond basic ATLS.

I think a program's senior residents are one of the best measures of their quality and these are residents I aspire to be like. Above all else, the teaching faculty were some of the most genuine, down-to-earth physicians I have worked with.

Why I chose this program/location for my training

I did an audition rotation here and absolutely loved it! The residents felt like a little family—super welcoming and really connected beyond work. The faculty and residents were so kind, loved teaching, and made sure we got hands-on experience! You get the best of both worlds between the two campuses: unopposed procedure experience, high acuity, and diverse patient populations. Plus, West MI summers on the lake are top tier.

Hobbies/interests outside of work

Outside of work, I enjoy rock climbing, gymnastics, and playing pickleball. I also attend a lot of live music / concerts and love to travel when I can.

Why I chose this program/location for my training

Trinity Health Muskegon was my first audition of 4th year. I did not know much about the program at the time but my wife grew up around the area and having family close is always a good thing. After the first few shifts I was blown away by the acuity of patients coming into the ED. The residents and attending were amazing teachers and truly cared not only about the patients but also my learning. 

Another reason I chose West Michigan EM Residency is that it is unopposed, meaning there are no ortho or surgery residents at this hospital, which means the ER does many of the procedures that would normally be relegated to ortho or surgery residents. Trinity Health Muskegon is a level 2 trauma center which leads to many traumas being brought to our door.

Hobbies/what I do outside of work

Outside of work, I enjoy hunting, fishing, weight lifting, basketball and wrangling my children.

Why I chose this program/location for my training

There are so many things I love about this program. First, the fact that it’s a four-year program means I’ll have the time to truly master my skills. I also appreciate the lack of competition for procedures and the opportunity to work closely with attendings.

I wanted to train in a place that genuinely values unity and kindness, and during my interviews with the faculty and residents, I quickly realized how warm and supportive everyone is. I knew I wanted to be a part of that. Choosing this program was easy; it checked all my boxes.

Why I chose this program/location for my training

West Michigan has been home to me for the last decade. When I was looking at emergency medicine residency programs, geographic location was really important for me to stay in West Michigan. Doing an audition rotation at Trinity Health Muskegon during my fourth year was the greatest influence on me for choosing this program. High-volume, sick population, and unopposed procedures were certainly high points, however, one of the greatest draws for me was seeing the mutual support and comradery amongst the residents.

As a medical student, I felt so welcome and included as part of the team, that I knew that this program would be a great fit for me to train at for the next four years.

Hobbies/interests outside of work

I spend most of my time with my family and church. I greatly enjoy most all outdoor activities.

Why I chose this program/location for my training

Walking away from my interview with this program, I knew it was “the one.” My decision was largely based on how I felt after that experience, but the program also had everything I was looking for: passionate educators, strong resident culture and camaraderie, a family-friendly attitude, procedural opportunities unopposed by anesthesia or surgical residents, an excellent EMR, exposure to a physician-owned EM group, and opportunities for moonlighting later on in training.

The Michigan outdoors and the opportunity to live in a lake town were also great motivators—and affordable housing (an extremely pleasant surprise in this location) made it all the more attractive. Choosing West Michigan as my #1 choice for emergency medicine has been the best decision I've made so far in medical training.

Hobbies/interests outside of work

Outside of work, I enjoy playing soccer, hiking, 3D printing/modeling and spending time with my wife and daughter.

Why I chose this program/location for my training

Emergency Medicine (EM) has been my goal since high school! Never knowing what/who is coming in the ED next, seeing all age ranges and a wide range of disease processes was why I fell in love with EM. I chose Trinity Health Muskegon because I wanted to maximize my learning with unopposed procedures, in a sick population, with a high volume ED. For that reason, the 4 years was a plus in my book.

I would rather be over-prepared than under!

Hobbies/interests outside of work

Anything outdoors! I love hiking, running, kayaking, rock climbing, etc. I also have an artistic side; I love painting, sketching and photography.

Why I chose this program/location for my training

I was looking for a program where I could really dive into my patient care. I didn’t want to simply train as someone that sits behind a computer and calls others to do my bidding. Trinity Health Muskegon, as it is an unopposed program, gives the opportunity to do all the procedures that you otherwise might have to hand off. I also felt right at home when I came for my audition rotation.

I made plans on making West Michigan my new home shortly after moving up here so from a life standpoint I am thrilled. Finally, the fact that this is a four year program makes me confident that I will leave here feeling confident that I will have the tools to tackle anything coming my way once I am on my own.

Hobbies/interests outside of work

I absolutely love to golf, which is both a blessing and a curse. I enjoy hiking and biking with my fiancee as well as exploring new areas in Michigan and checking more and more national parks off the list! Computer games are also a hobby of mine when I get some free time. I enjoy watching golf on television, Formula 1, and just going out for a drive on a nice windy road.

I chose emergency medicine because I love the fast paced, ever-changing environment. I also love the ability to be able to perform procedures and the acuity of patient care.

Muskegon was my base hospital during my last two years of medical school, and I really enjoyed being there. I am from West Michigan and wanted to stay near family and friends. I also thought the patient population, interesting pathology and high volumes would provide me ample learning opportunities. The residents and physicians also made me feel welcome and a part of the team, which was really important to me.

While on an EM Ultrasound rotation in Muskegon, I was impressed by the quality of education/experience the program provides and the comradery between the residents and attendings. I’m excited for the opportunity to train at an unopposed program with multiple clinical sites.

Hobbies/interests outside of work

I enjoy spending time outdoors with family and friends. I am an avid runner, snowboarder, surfer and ice climber. I’m excited to take advantage of the running and biking trails in West Michigan over the next few years and hope to get a few post-shift surf sessions in Lake Michigan as well.

At Trinity Health Muskegon, I get to work as an emergency medicine physician handling all manner of cases, performing procedures, and get to act as the team lead when running resuscitations. Most of all, I felt like it was the best fit for me. I chose emergency medicine because I love the variety of patients and disease states, the procedures, learning to predict the unpredictable and being able to learn from the different cases.
