Businesses across the Northern Rockies and High Plains face complex legal challenges every day. Energy projects demand precise permitting. Commercial disputes can threaten operations. Estate plans must protect generational wealth. Finding counsel that understands both the local landscape and national standards is essential.
Crowley Fleck PLLP stands as one of the oldest and largest full-service law firms in the region. With roots dating to 1895 and roughly 150 attorneys across 11 offices in Montana, North Dakota, and Wyoming, the firm delivers local insight paired with national-level experience. This guide explains the firm’s history, core practice areas, regional strengths, and why it remains a trusted partner for corporate executives, energy companies, landowners, and individuals.
A Legacy of Excellence Spanning More Than 125 Years
Crowley Fleck PLLP traces its beginnings to 1895. W. M. Johnston opened a law practice across from the Northern Pacific Depot in Billings, Montana. From the start, the firm served local families, ranchers, lenders, hospitals, and early energy interests.
In Bismarck, North Dakota, Alvin C. Strutz and Clifford Jansonius founded a firm in 1945. Strutz later became Chief Justice of the North Dakota Supreme Court. Ernest R. Fleck joined in 1948, building a strong practice focused on oil and gas, energy, litigation, and commercial matters.
On January 1, 2009, the Montana firm Crowley, Haughey, Hanson, Toole & Dietrich PLLP merged with Fleck, Mather & Strutz, Ltd. The combined entity became Crowley Fleck PLLP. The merger created a true regional powerhouse. Offices expanded into Casper, Butte, Sheridan, and Cheyenne. Today the firm maintains locations in every capital city of its three-state footprint, enabling effective governmental, lobbying, and regulatory work.
This history matters. Attorneys who have practiced in the region for decades understand the unique interplay of federal, state, tribal, and local rules that shape business in the Northern Rockies and High Plains.
Expansive Footprint Across Montana, North Dakota, and Wyoming
Crowley Fleck PLLP operates 11 offices:
- Montana: Billings (headquarters), Bozeman, Butte, Helena, Kalispell, Missoula
- North Dakota: Bismarck, Williston
- Wyoming: Casper, Cheyenne, Sheridan
This presence allows seamless representation across state lines. A client with operations in the Bakken, Powder River Basin, and Montana’s energy corridors can work with one coordinated team rather than multiple disconnected firms. Lawyers are licensed in the three core states and often hold licenses in surrounding jurisdictions including South Dakota, Colorado, Idaho, and others.
The firm’s regional dominance stems from this combination of geographic coverage and deep institutional knowledge. Clients gain counsel who know the local courts, agencies, and business culture while drawing on resources comparable to larger national firms.
Comprehensive Practice Areas for Businesses and Individuals
Crowley Fleck PLLP offers a full range of legal services. The following sections highlight key practice groups that serve the target audience of corporate decision-makers, energy companies, and private clients.
Commercial Litigation Legal Counsel
Commercial litigation forms a core strength. The firm handles contract disputes, business torts, construction claims, product liability, and complex commercial cases in state and federal courts throughout the region. Attorneys manage matters from early case assessment through trial and appeal.
Insurance defense work is equally robust. The firm represents insurers and insureds in coverage disputes, bad-faith claims, and defense of underlying lawsuits. This dual capability proves valuable for businesses seeking consistent counsel on both sides of the risk equation.
Clients benefit from coordinated strategy across offices. A dispute arising in Williston can draw on litigators in Billings or Casper without losing continuity.
Energy and Natural Resources Attorneys
Energy law and natural resources law represent signature strengths. Crowley Fleck PLLP maintains one of the largest dedicated groups in Montana, North Dakota, and Wyoming. Work spans oil and gas, coal and hard-rock mining, renewables, pipelines, transmission, and environmental compliance.
Oil and gas attorneys regularly appear before conservation commissions in all three states. They handle spacing, pooling, unitization, and operations matters. Title examination is a particular specialty, covering fee, federal, state, Indian, patented, and unpatented claims, including complex riverbed issues. The firm prepares title opinions for acquisitions, financing, drilling, and division orders.
Mining clients receive counsel on claim issues, royalties, permitting, and transactions. Renewable energy work includes wind and solar project development, financing, and related agreements. Environmental and regulatory support covers permitting, compliance, and litigation before state and federal agencies.
This depth positions the firm as a primary resource for energy and resource companies operating across the Northern Rockies and High Plains.
Banking and Finance Law
Banking and finance law supports lenders, borrowers, and financial institutions. Attorneys handle commercial lending, secured transactions, creditors’ rights, bankruptcy, and restructuring. Real estate finance, agricultural lending, and multi-state financing arrangements form regular work.
The firm advises on public finance, bond offerings, and securities matters. This practice serves community banks, regional institutions, and national lenders with interests in the region.
Healthcare Law
Healthcare law addresses the full spectrum of issues facing providers. Clients include hospitals, physician groups, community health centers, and related organizations. Services cover business transactions, compliance, HIPAA and health information privacy, joint ventures, medical staff relations, Medicare and Medicaid, licensing, and risk management.
When disputes arise, the firm’s litigators handle medical malpractice defense, peer review, and regulatory proceedings. Coordinated advice helps healthcare organizations navigate an evolving regulatory environment while focusing on patient care and operational goals.
Tax and Estate Planning
Tax and estate planning serves both individuals and businesses. Attorneys design wealth-transfer strategies, administer estates and trusts, and address related tax issues. Closely held business succession planning is a frequent focus, especially for family-owned ranches, farms, and energy-related enterprises.
The group also advises on tax-exempt organizations, employee benefits, and transactional tax matters. Clients receive practical guidance that balances tax efficiency with family and business objectives.
Additional Core Services
Real estate work includes commercial acquisitions and sales, farm and ranch transactions, leasing, zoning and land use, water rights, and conservation easements. Employment law focuses on management-side counseling, policy development, and defense of claims. Governmental affairs and lobbying leverage the firm’s presence in state capitals. Intellectual property and technology counsel covers trademarks, licensing, and related commercial and litigation matters.
Why Regional Expertise Matters for Corporate Clients
National firms often lack the day-to-day familiarity with state agencies, local judges, and industry norms that shape outcomes in Montana, North Dakota, and Wyoming. Crowley Fleck PLLP bridges that gap. Attorneys know the practical realities of permitting before conservation commissions, negotiating surface-use agreements on split estates, and navigating tribal jurisdiction issues.
At the same time, membership in prestigious networks expands reach. Crowley Fleck PLLP is the exclusive Montana member of Lex Mundi, the leading network of independent law firms with coverage in more than 100 countries. Additional affiliations include the Employment Law Alliance and State Law Resources. These relationships give clients access to coordinated counsel for multi-jurisdictional or international matters without sacrificing regional focus.
Recognition from Chambers USA, Best Lawyers, and Super Lawyers further confirms the quality of the bench. Many attorneys have practiced their entire careers with the firm or its predecessor organizations, creating institutional continuity that benefits long-term client relationships.
Serving Landowners, Executives, and Individuals
While the firm is known for sophisticated commercial and energy work, it also serves private clients. Estate planning, real estate transactions, and personal litigation receive the same level of attention. Landowners dealing with mineral development, surface disputes, or conservation opportunities find experienced counsel. Executives managing corporate risk or personal wealth receive integrated advice across practice groups.
Pro bono service remains a firm priority. Since 1996 the firm has maintained a formal in-house pro bono program, reflecting a commitment to the communities it serves.
How to Engage Crowley Fleck PLLP
Potential clients typically begin with a consultation focused on the specific matter. The firm’s size allows it to assemble the right team quickly, whether the issue requires energy regulatory specialists, commercial litigators, or estate planners.
