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!

Forget the usual tourist attractions… we took Sangavi and Neha to meet the real Wyoming celebrities. 🦬 First buffalo sighting officially in the books!

To everyone who stopped by our table — thanks for hanging out with us! And if we convinced you that accounting can actually be fun… our work here is done. 😂

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.

Only in Wyoming…

A few members of our team recently traded spreadsheets for cowboy boots to lend a hand at a teammate’s family ranch branding.

We’re grateful for opportunities like these to support one another outside the office… and to experience a little bit of authentic Wyoming along the way.

Nothing says summer at PMCH quite like our annual Parade Day picnic! It may have been a hot one, but we enjoyed taking a break from the office, sharing a meal, catching up, and spending time together. After the picnic, a few of us even cooled off by floating the river to wrap up a great day.

It’s moments like these that remind us one of the best parts of PMCH is the people we get to work with every day.

Mike and Thomas had the opportunity to attend Wyoming Employer Day during Cheyenne Frontier Days! It was a great chance to connect with employers from across the state, share what makes PMCH a great place to build a career, and celebrate Wyoming’s incredible workforce. We always enjoy getting to meet new people and represent our firm at events like these.
