Mike Arnold is experienced in jury trials and complex criminal and civil litigation involving multiple parties and witnesses, voluminous discovery, expert witnesses, and high stakes.

Mike was managing partner of Arnold Law for 10 years and has been the chief trial lawyer of the firm until he recently took on a more advisory role for the firm’s trial lawyers.  Mike’s leadership brought a two-attorney law firm into the powerhouse it is today.  Mike is also the author of Finishing Machine, a book about a client accused of murdering an unarmed man (a must read for anyone wishing to get a firsthand look at courthouse politics).  He also has a steady presence in national media including a CBS 48 Hours episode entitled “Trail of Tears” (watch the full episode) and his high-profile public response to the Malheur Wildlife Refuge Occupation through his representation of Ammon Bundy.


In 2017, Mike co-founded an agribusiness startup and raised $1,000,000 of investor money in less than four months, quickly launching his business as one of the top firms in Oregon in the cannabis space. He has utilized his unique brand of strategic thinking, his traditional Midwest farming skills and his legal knowledge to position his new enterprise “big ag” meets “big pharma” by quickly becoming one of the largest farm conglomerates in Oregon while also building a strong executive team with deep roots in traditional businesses and agronomy.

Attorney Practice PHILOSOPHY

Mike’s practice philosophy is simple: know more about the facts and law than the other lawyer, investigators, experts, and court. Hard work wins cases. Mike does not just ferry offers from the other side to his clients. He prepares every case for settlement as if it were going to trial.

Education and Background

Mike grew up in Parkville, Missouri, a small Midwestern suburb along the Missouri River, northwest of Kansas City. His father was a pipefitter and his mother a screen printer. He attended college at Truman State University in Kirksville, Missouri, where he started all four years on Truman’s nationally-ranked rugby team and ultimately graduated summa cum laude.

After graduating from Truman State in December of 1997, he and Jacy Arnold moved to Eugene to attend law school at the University of Oregon where Mike was honored with a prestigious Wayne Morse Fellowship.

For two years during law school, he worked two jobs at once: one at a small personal injury firm and the other at the Lane County District Attorney’s Office. At the DA’s Office, he conducted grand jury, allowing him to see the inner workings of this secret body. He prosecuted many jury trials, including a felony Marijuana grow, DUIIs, assaults, driving crimes, etc.

In 2014, Mike was listed as one of Oregon’s top trial attorneys by the National Trial Lawyers Top 100 Trial Lawyers after a selection process that included peer nominations combined with third-party research (criteria includes reputation among peers, judiciary, public; previous year’s verdicts as a trial lawyer; etc.). In 2014, Mike was named in The Eugene Weekly‘s “Best of Eugene” awards as “Eugene’s Best DUI Lawyer.”

Mike is also rate “Distinguished” (4.4/5.0) by Matindale-Hubble’s attorney peer-review rating system.

Employment History

After graduating from law school in 2001, he continued working at the litigation firm representing clients in personal injury jury trials and defending clients accused of crimes. In 2002, he joined his wife Jacy at Arnold Law Office, where he focused on personal injury litigation and prosecution for the city of Eugene.

During his first few years of practice he was averaging more civil jury trials per year than most seasoned plaintiff’s lawyers. He was also averaging a little over one criminal jury trial a month as well.

While preparing for and trying cases by day, at night he would sharpen his skills by reading and re-reading the Oregon evidence treatise, books on depositions, books on trial skills, expert materials (DSM-IV), etc. It is not called the practice of law for nothing. Mike realized early on that if you are not regularly trying cases and increasing your knowledge-base, your trial tools do not stay sharp.

Practice Interests

Mike enjoys advising his attorney team in complex litigation, involving high stakes (financial or liberty interests), complicated legal issues or expert witnesses, confusing fact patterns with lengthy timelines, or multiple parties.

Mike enjoys meeting juries all around the state, particularly in the more rural counties. In the civil context, he has successfully resolved cases in Federal and state courts, including jury trials in Federal Court in Eugene and in state court in Lane, Marion, Linn, Lincoln, and Josephine Counties. He has successfully litigated business, personal injury and employment cases before juries.

In the criminal context, he has won dismissals for clients in federal court in Eugene and Spokane, Washington, and in state and municipal courts in many counties and towns, including Jackson County, Douglas County, Deschutes, Lane, Lincoln, Eugene, Cottage Grove, Springfield, etc.

In 2013, he won a 45-minute not guilty verdict in a Manslaughter in the First Degree trial. In May 2014, he won a not guilty jury verdict for a client falsely accused of driving under the influence of Vicodin and Marijuana in Jackson County Circuit Court in Medford. In December 2014 he won a 17-minute not guilty verdict of a client falsely accused of assaulting his adult stepson by throwing him into a truck’s mirror. In April 2015, Mike won a 14-minute not guilty verdict in a .09% BAC DUII. In February 2017, he won a seven-count not guilty verdict for a client accused of a marijuana DUI car crash (assault, reckless endangering, and reckless driving).

In addition to marijuana DUII trials, Mike has also advised marijuana businesses and is a member of the Oregon State Bar Cannabis Law Section.

In May of 2015, Mike resolved a Murder case involving a retired professional mixed martial artist who shot and killed an unarmed man with an AR-15 after a traffic collision. After over 15 months of litigation, the case settled with a criminally negligent homicide plea. He and co-counsel Emilia Gardner wrote a highly-reviewed book about the case called Finishing Machine (available in paperback and eBook on Amazon.com).

When asked by newer lawyers about practical advice in the practice of law, Mike offers the following: “All you need to do to be a good lawyer is return all of your phone calls, treat people as you want to be treated, work hard until there are no hours left in the day and then hire more staff, and destroy liars and exaggerators in cross-examination.”

Hobbies and Interests

Mike works hard and plays hard. After work, by the light of his headlamp, he enjoys tending to his herd of rare American Guinea Hogs, raising poultry (chickens, turkeys, and quail), and fixing fence on their small farm outside of town. He and Jacy also have a large garden and small orchard.

They can their garden produce and often turn their grapes, apples and pears into wine, hard cider and hard perry. They also have a moderate-sized beekeeping operation which assists in higher-than-average yields in the garden and orchard due to having hundreds of thousands of pollinators in their backyard. That also allows his family (and clients) to enjoy a spoonful of honey in their coffee and gives them plenty of raw materials for their homemade mead. At the Lane County Fair, Mike earned a blue ribbon for his wine making.

After retiring a second time from Eugene Rugby Club in 2008, he began devoting his scarce free time to whitewater. When not relaxing on the farm, Mike now enjoys spending his time rafting class IV and V rivers in the Pacific Northwest. A photograph of him and his rafting partner dropping off of 30-ft. Big Brother Falls on the Upper White Salmon was featured in Canoe and Kayak Magazine’s Whitewater Annual in 2011.
