Who We Are

After decades of case by case collaboration over the course of their combined one hundred years plus of practicing law, John Quaintance and Murray Ogborn, with the encouragement of his partners, formed Ogborn Mihm Quaintance, PLLC, in June 2019 for the practice of law in South Dakota and the representation of South Dakotans and their neighbors in South Dakota courts. OMQ makes available to its clients the integrated resources of Ogborn Mihm, LLP, from Denver and Quaintance Law Office P.C. in Sioux Falls, blending experienced business, commercial, and transactional lawyers with proven and accomplished litigators to provide the best of representation to our clients, from business, creditor’s rights, and real estate matters to commercial, construction, and catastrophic injury litigation. Although our Denver and Sioux Falls offices are connected by state of the art technology, our lawyers and staff are committed to personal contact with clients and will, if or when preferable, meet with you face to face. The combined qualifications of more than twenty lawyers between three offices in Denver, Sioux Falls, and Los Angeles provide experience and top-end talent in high stakes transactions and litigation.

Our Clients

We represent individuals and companies needing advice to safeguard their rights or experienced trial lawyers to litigate their rights.

How We Help Our Clients

We pride ourselves on our legal skills and our ability to advise businesses as well as try any case, regardless of size or complexity. John Quaintance is the core of OMQ’s business transaction law practice. With decades of experience, both are qualified to advise businesses and individuals and help them achieve their business goals. Similarly, our highly experienced trial teams always keep in mind the client’s personal, business, and litigation goals while preparing cases for trial. In either circumstance, we include clients in case planning at every step of the process. Our goal is to quickly respond to our clients’ questions and concerns and address their practical needs. Additionally, our transactional experience informs our litigation and vice versa, providing a collaborative approach to any matter.  OMQ is a pioneer in the use of focus groups, jury research, and courtroom technology to tell our clients’ stories when trial is necessary.
