About
Thomas C. Orr is a partner at Orr McDonnell Law in Missoula, Montana who handles civil litigation and a broad range of matters involving real estate, business law, landlord-tenant issues, contracts, family law, adoptions, and personal injury. His practice combines dispute work with advice on property, commercial, and individual legal concerns. The work requires careful attention to the governing law, factual record, deadlines, and practical consequences for the client.
Orr earned a Juris Doctor from the University of Montana School of Law and a Bachelor of Science in Criminal Justice, with honors, from Montana State University. His legal training followed service in the United States Navy and prepared him for both public-sector and private-practice responsibilities. This background supports careful analysis, clear writing, and practical problem solving in matters involving civil litigation, real estate, business law, contracts, family law, and personal injury.
Orr previously clerked for Judge Jeffrey Sherlock and spent nearly a decade with the City of Missoula as a Deputy City Attorney, working as both a criminal prosecutor and civil attorney. He opened his private firm in 2000 and has since represented clients in litigation and transactional matters across several practice areas. Across these matters, Orr evaluates the legal and factual issues that shape strategy, negotiation, and the available path toward resolution.
Thomas C. Orr has also served as a public school trustee and on a local housing authority board. That combination of litigation, municipal, and community experience supports a practical approach to disputes, property matters, contracts, and family-related legal issues. This approach keeps legal strategy connected to the client’s practical objectives and the specific demands of each matter.
