From intern to full-time team member!

We’re excited to officially welcome Josie to the PMCH team as a full-time employee.

Josie spent two summers with us as an intern before joining the team full-time, so we’re especially excited to see her continue to grow with PMCH. She brings the same personable, lively, and humorous energy she’s always had, along with a growing passion for the work.

We’re so glad you chose PMCH, Josie, and we can’t wait to see where this next chapter takes you!

Meet Jill, PMCH Intern!

Jill says her favorite part of working at PMCH is the people and the fact that there’s always something new to learn. These days, she’s spending most of her time working through audit binders and getting familiar with the systems.

Friends would describe Jill as fun to be around, always ready with a random fact or a funny story about her kids. Outside of work, she loves camping, hiking, biking, reading, traveling, and spending time with friends and family.

We’re excited to have Jill on the team and can’t wait to see all she learns and accomplishes this summer!

The PMCH team had a great time attending the Industry Fair during Saddle Up at the University of Wyoming!

It was a pleasure meeting so many incoming students, hearing about their goals, and sharing what a career in public accounting can look like. We always enjoy connecting with the next generation of professionals and helping students explore the opportunities ahead.

Thank you to the University of Wyoming College of Business for hosting another great event. We hope to see many of the students we met again at Meet the Firms in a few weeks!

Here’s why Thomas says you shouldn’t miss Meet the Firms:

He showed up without a perfect resume or a plan, and it led to a career at PMCH.

If you’re wondering whether it’s worth going, take it from someone who’s been in your shoes.

As another summer comes to a close, we’d like to thank our incredible interns for spending the season with us.

Maisynne embraced the world of auditing with curiosity and compassion, always eager to ask questions, learn, and grow. Her reliability and positive attitude made her a wonderful addition to the team.

Brendan brought enthusiasm and a passion for learning every day. From connecting classroom concepts to real-world audits to collaborating with teammates, he made the most of every opportunity. He also kept the office well-fed with homemade bagels and cookies and somehow found a way to turn just about any situation into the perfect meme. His creativity, humor, and willingness to dive into something new made him a wonderful addition to the team.

Emily impressed us with her organization, eagerness to learn, and thoughtful approach to every task. Whether she was completing training, working through her audits, or planning her next project, she brought a positive attitude and a willingness to grow.

Thank you all for your hard work, fresh perspectives, and the energy you brought to PMCH this summer. We loved having you on the team and can’t wait to see all you’ll accomplish in the future. Best of luck this school year, and we’ll be cheering you on!

We’re excited to welcome our newest team member!

Luke says his favorite part of PMCH is the people. He appreciates how welcoming and helpful everyone is, even when he’s “bothering other accountants with questions” throughout the day.

Outside of work, Luke enjoys spending time with family, hiking, weightlifting, and reading. Relaxed and funny, he’s already a great addition to the PMCH team.
