We're delighted to introduce Diane O. Long as the newest member of our Montrose office! Bringing a wealth of expertise in commercial litigation, construction law, complex business litigation, and labor and employment matters, Diane is well-equipped to offer invaluable support to our clients across Southwest Colorado.

After four years of practice as an Associate at national law firms, Diane is excited to bring her practice to the Western Slope. With her vibrant personality and extensive background in litigation, she is a welcome addition to our firm.

In law school, Diane showcased her legal acumen as an articles editor of the Ohio State Law Journal and a member of Ohio State’s Moot Court team. She also distinguished herself in her Bachelors’ degree program, graduating magna cum laude from Marshall University in Huntington, West Virginia. 

When she's not in the office, you'll likely find Diane chasing powder on her snowboard, backcountry hiking and camping, visiting antique stores in search of art, or watching a World War II documentary. Diane's passion for exploration extends beyond the Western Slope into the four-corners region, where she delights in adventuring through and learning about the incredible history of the Mountain West with her faithful dogs, Angus and Olive.
