Sioux City's Estate Planning, Real Estate, and Business Law Attorney — Practicing Iowa Law Since 1976
Serving Woodbury County and Northwest Iowa
John Daniels has practiced Iowa law for nearly 50 years, serving Sioux City families, farmland owners, and out-of-state heirs with wills, trusts, and estate plans built to last.
One Attorney. Four Decades of Iowa Legal Experience.
Daniels Osborn Law Firm is John Daniels — a solo practitioner admitted to the Iowa Bar in 1976, with a J.D. and MBA from the University of Iowa. Before returning to private practice, John served as General Counsel and CEO of St. Luke's Health System, one of Sioux City's largest regional medical centers. That combination of courtroom experience, institutional leadership, and deep community roots is uncommon in a solo practice — and it's what clients in Sioux City and across Northwest Iowa have relied on for nearly five decades.
Every matter is handled personally by John. No intake staff, no referral routing, no paralegal handoffs. When you call, you reach your attorney.

John was extremely helpful settling my dad’s estate, making sure all documents were filed in court correctly, and even settling a small posthumous lawsuit. He kept me up to date on progress of estate progression and was very approachable with any questions I had. Very competent!
Michele V.
John took on a very complicated real estate transaction for our family. We are in California and property is in Iowa. From our first meeting John was excellent and personable. He kept us informed and updated on progress all along the way, and explained things in laymans terms so they were easy to understand. We couldn't ask for a more professional attorney to handle our real estate transaction. We felt very comfortable with John handling everything for us...even from afar!! 5+++stars!

Sid M.
John has assisted us with multiple property acquisitions as well as the formation of our LLC, and his expertise has been invaluable every step of the way. One of the acquisitions turned out to be particularly complex, requiring extensive coordination with both city and county officials. Despite the challenges, John navigated the process with skill and persistence, ultimately securing everything we expected and even more. His professionalism, knowledge, and dedication truly set him apart. We highly recommend John for any real estate transactions—he’s someone you can trust to get the job done right.

Vicki K.
John Daniels has completed numerous Title Opinions for my clients in my 30 year real estate career. I highly recommend John and feel confident my clients are in the best hands. He has reviewed documents and helped solve Title issues numerous times. I referred John to family for estate planning and they were extremely happy with his services. John helps you resolve issues and always goes above and beyond! He has an eye for detail and is a very competent attorney!
Jan B.
In residing outside of IA, I needed an IA attorney who would not only be able to represent me in tackling the state’s complex estate/probate and guardian/conservatorship laws but also an attorney that would be willing to do so remotely. John checked all of those boxes and much more. He’s an expert in those fields but also one of the most professional, empathetic and kind attorneys that I have worked with especially given the immediacy of circumstances/decisions that I faced. I feel very fortunate to have been referred to John and highly recommend him to others.

Estate Planning Questions — Answered Directly
What's the difference between a will and a trust?
A will goes through probate, which is a public court process. A trust does not — it allows assets to pass privately, often faster, and with more control over timing and conditions. Which one fits your situation depends on your assets, your family structure, and your goals.
Can I manage an Iowa estate from out of state?
Yes. John works regularly with executors, trustees, and heirs who live outside Iowa but are responsible for Iowa-based estates, farmland, or trust administration. Most of the work can be handled remotely.
Do I need both a will and a trust?
Possibly — and the answer depends on specifics, not a general rule. John will walk you through what each document does and help you decide based on your situation, not a standard package.
How do I keep the family farm in the family?
Custom estate plans, trusts, and entity structures can preserve farmland ownership and reduce conflict across generations. Iowa farm families in Woodbury, Plymouth, Sioux, and Monona Counties face specific considerations — John has handled this work for decades.
How do I find a trusted estate planning attorney in Sioux City, Iowa?
Look for someone with a verifiable record in Iowa — bar admission year, specific credentials, and direct client access. John Daniels has been licensed in Iowa since 1976 and handles every matter personally.
