What Mackoff Kellogg Law Firm does

Mackoff Kellogg Law Firm is a privately held professional corporation (P.C.) headquartered at 38 2nd Ave E, Suite A, Dickinson, North Dakota. Founded in October 1889 by Leslie A. Simpson, the firm is the oldest continuously operating law firm in western North Dakota and eastern Montana, evolving through several name iterations to its current form adopted in 1998. It operates a single office location and provides legal representation across North Dakota, South Dakota, and Montana, with attorneys also admitted to U.S. federal courts and, in one case, the U.S. Tax Court.

The firm offers a full-service general practice spanning nine areas: oil, mineral and gas law; family law; estate planning and probate; litigation; criminal defense; creditors' rights; real estate law; commercial law; and business formation. Services are billed on a quote-based, fee-for-service model with monthly billing cycles, processed through LawPay's online payment platform. Marketing is conducted primarily through community reputation, referrals, free consultations, and a basic website built by Frontrunner Technologies LLC. No proprietary technology stack, AI capabilities, or automation tools are disclosed.

The client base spans individuals, sole proprietorships, SMBs (manufacturers, construction companies, local financial institutions, nonprofits), and government entities. The firm holds anchor municipal appointments as City Attorney and City Prosecutor for the City of Dickinson and State's Attorney for Golden Valley County, plus engagements with the City of Dunn Center and City of Gladstone. Ownership rests with Managing Partner Christina M. Wenko, who became sole shareholder in March 2020. The firm employs approximately 50 staff including five attorneys (two associates, two Of Counsel, and the Managing Partner), supported by an office manager. Revenue is not publicly disclosed.
