Patti Stanfill, CPA, Owner

Education: National College: Bachelor of Science in Accounting
Certifications: Certified Public Accountant, QuickBooks Certified ProAdvisor

My name is Patti Stanfill and I grew up in Glendive, Montana. Upon graduation in 1993, I wanted to experience a larger town and attended Montana State University in Bozeman. A wedding ring landed on my finger and we moved to Rapid City, SD, where I finished my accounting degree in 1997 at National College in Rapid City. I graduated with a Bachelor of Science degree in Accounting, Magna Cum Laude. After college graduation, we realized nothing beats Montana so we moved to Billings, where I started working for Ortt & Co. CPAs, Inc. I passed my CPA exams in 1998 and achieved my goal of becoming a Certified Public Accountant. In 2006, I became a shareholder of Ortt & Co. CPAs, Inc. with Bryant and Madge Ortt. In 2010, I bought out the prior owners and became the sole owner of the firm. In my spare time (ha ha), I enjoy spending time with my very supportive husband, Jay, and three kiddos.

Education: University of Wyoming: Bachelor of Science with Honor in Accounting and a Minor in Music
Certifications: Certified Public Accountant, Certified Management Accountant

My name is Sara Collins and I grew up in the “thriving metropolis” of Fort Peck, Montana. Believe me, growing up on the highline will make anyone tough! I received my bachelor’s degree in accounting and a minor in music from the University of Wyoming - Go Cowboys! I worked for a year and a half at a small CPA firm in Laramie, WY before I decided to move back to Montana to be closer to family. I ended up with a house in Joliet, MT and a job in Billings, MT. I worked ten years for a regional firm in Billings before finding Ortt & Co. CPAs, Inc. in January 2012. Along the way, I passed the exams to become a Certified Public Accountant (CPA) and a Certified Management Accountant (CMA). I enjoy spending time with my family, especially my two daughters, my husband, my two dogs, my cat and all other animals that choose our home to be theirs.

Genny Wink, CPA

Education: Montana State University-Billings: Bachelor of Science in Accounting
Certifications: Certified Public Accountant

My name is Genny Wink and I was born & raised in Montana. I graduated from Montana State University Billings with a degree in Accounting and after graduation I moved to Nashville, Tennessee where I worked as a CPA in a few different public accounting firms. After close to 8 years in the Volunteer State with a year and a half of that in Los Angeles, I started to miss my Montana roots and decided to make the move back to be closer to my family. I joined Ortt & Co. CPAs, Inc. in May 2017 and love serving clients to help them be as successful as possible. I have three yellow labs that are my world and am a huge dog lover and if I had the money I would own lots of land and save every dog that I could. I hate the winter time so I chose to be a CPA so I can just work indoors all the time from January to April and pretend that winter never even happened. I enjoy spending time with my dogs, reading and hanging with my family in my downtime.
