Michael’s Philosophy of Client-Centered Trials

Michael is student and practitioner of the art of trial persuasion. Michael believes that every client has a simple and compelling story, regardless of how complex the case may appear on the surface. Thus, Michael and his team make the client’s story the center of every case, and work tirelessly to find and tell the client’s story. Michael and his team routinely use focus groups, multi-media technology and cutting-edge trial techniques to discover and best present the client’s case at trial.

While Michael believes that a client is best served by intense preparation, tenacious representation, and unfailing professionalism, he and his team also under understand that a client’s goals and objectives are paramount. Thus, the team includes the client in every major decision of the litigation process. Michael and his team never forget that, ultimately, the case is the client’s case.

Michael’s Expertise in Legal Malpractice Litigation

Michael has prosecuted or defended hundreds of legal malpractice lawsuits, has tried many such cases, and has also served as an expert witness in many such suits.

Since 2005, Michael has served as an author and managing editor of Lawyers’ Professional Liability in Colorado, 2017 Ed. (Michael T. Mihm ed., CLE in Colorado, Inc., 2017). This two-volume, 57-chapter treatise, updated annually, focuses on lawyers’ professional liability and legal ethics issues.

Michael’s legal malpractice clients come from all walks of life, but are most often companies or business people. His legal malpractice cases typically involve underlying business or real estate transactions, including tax, estate planning, intellectual property, patent law, land use, and many other matters. However, Michael also handles non-business related legal malpractice cases. For example, Michael and his colleague, Elizabeth “Betsy” Hyatt, recently represented pro bono a young man who was sentenced to life in prison at age 15 for a murder that he did not commit, and who, after 14 years in prison, was released from custody. Michael and Betsy sued the negligent criminal defense counsel on the young man’s behalf and recovered a confidential settlement.

Michael’s Expertise in Commercial and Corporate Litigation

Michael also has a significant business and corporate litigation practice. Michael’s business litigation often involves claims arising from breach of contract, corporate control, oil and gas transactions, real estate disputes, oppression of minority business owners, partnership disputes, theft of trade secrets, intellectual property disputes, computer fraud, and claims arising from breaches of fiduciary duty and other misconduct by company insiders.

Michael’s Expertise in Personal Injury Litigation

Michael also personally tries select medical malpractice, wrongful death and catastrophic personal injury cases. For example, in 2017, Michael and his team tried (and lost) a medical malpractice case, but then negotiated a $3.0 million settlement in a wrongful death case arising from an automobile-bicycle accident. Michael’s firm has a significant personal injury practice, and recently obtained a $100 million settlement in a products liability claim arising from a helicopter crash.

Michael’s Trial Experience

In recent years, Michael has tried cases to verdict or handled lawsuits in California, Colorado, Florida, Nevada, New Mexico, Oklahoma, Utah and Texas. In June 2017, Michael tried (and lost) a medical malpractice case. In October 2016, Michael obtained a nearly $2.0 million arbitration award (later confirmed as a judgment) in a breach of contract dispute on behalf of a minority owner being squeezed out of a recreational marijuana business. In June 2015, Michael obtained a jury verdict in a business fraud/partnership dispute that later resulted in a confidential settlement and favorable buy-out of our client’s partnership interest. In April 2014, Michael obtained a $2.5 million jury verdict on behalf of the owners of a prominent Colorado retail business in a legal malpractice case arising out of an attorney’s breach of fiduciary duty when aiding a trustee in an attempt to seize control of the family-owned company. In June 2013, Michael and his partner, Mike Ogborn, obtained a $12.8 million jury verdict in state district court of Salt Lake City, Utah. The verdict, then one of the largest plaintiff legal malpractice jury verdicts in U.S. history, arose out of a prominent law firm’s mishandling of a development application for an 8,650 acre ranch near Park City, Utah. Michael also represents clients in select probate or inheritance litigation matters, usually involving very large estates and usually at the request of probate lawyers when it appears that a matter is headed to trial.

Michael has been inducted as member of the American Board of Trial Advocates (ABOTA). He is a graduate of the Gerry Spence Trial Lawyer’s College in Dubois, Wyoming.

In 2003, Michael formed the boutique trial law firm of Starrs, Mihm & Caschette LLP to focus on plaintiff-side legal malpractice litigation and commercial and business tort litigation. In 2012, after both of Michael’s partners became district judges, Michael formed Ogborn Mihm, LLP, with the father and son team of Murray and Mike Ogborn.
