Most cover law firm performance in fragments. You read about a lateral hire one week, a single ranking category the next, and a revenue headline once a year.

I wanted to pull these puzzle pieces together. This profile delivers a complete, analytical look at where Polsinelli stands today.

We look beyond the superficial marketing brochures. We evaluate their market positioning, core profit metrics, rapid lateral expansion, and active litigation exposure.

Who Is Polsinelli?

Polsinelli is a prominent American law firm. Three young attorneys, including Jim Polsinelli, founded the firm in Kansas City, Missouri, in 1972. They launched the practice to serve business and real estate clients in the city’s historic Country Club District.

The firm expanded steadily over the following decades. They combined organic talent cultivation with aggressive, calculated law firm mergers.

Key historical combinations built their modern foundation. The firm completed a pivotal merger with St. Louis-based Suelthaus, PC, in 2004.

They executed a massive combination with Kansas City-based Shughart Thomson & Kilroy in 2009. These strategic moves created the nationwide corporate litigation and transactional platform that Polsinelli operates today.

How Big Is Polsinelli Today?

Polsinelli operates as an established Am Law 100 firm. This placement ranks it among the 100 highest-grossing law firms in the United States.

The firm’s physical footprint spans more than 25 offices nationwide. Their office network extends from Boston and New York on the East Coast to Los Angeles and Seattle in the Pacific Northwest. More than 1,200 active attorneys staff these locations.

The firm holds widespread legal accolades. Chambers USA recognizes Polsinelli with 70 ranked departments and 135 individually ranked attorneys across its national network.

Their practice depth covers diverse legal sectors, including healthcare, commercial construction, and intellectual property.

This broad distribution of ranked practices distinguishes Polsinelli from its peers. Many Am Law 100 firms rely heavily on one or two flagship practices to survive. Polsinelli maintains balanced operational strength across dozens of distinct transactional and regulatory departments.

Financial Growth: Inside The $1.21 Billion Year

The firm’s financial trajectory highlights its rapid upward mobility. Financial reporting compiled by The American Lawyer reveals that Polsinelli’s gross revenue reached $1.21 billion. This represents a 25.5% increase over the previous fiscal year. Net profit grew even faster, surging 33.6% to reach $722 million.

True firm health appears inside their core efficiency metrics. Revenue Per Lawyer (RPL) jumped 15% to hit $1.083 million. Profits Per Equity Partner (PEP) crossed a monumental threshold, surging to $3.07 million per equity partner.

2024 Gross Revenue: $964M	2025 Gross Revenue: $1.21B	25.5% Jump
2024 Partner PEP: $2.50M	2025 Partner PEP: $3.07M	23.0% Jump

CEO and Chairman Chase Simmons attributes this financial surge to historical preparation. He notes that multi-year investments in infrastructure are paying off.

Simmons emphasizes that the firm’s culture remains grounded despite the massive revenue spike. He points out that the firm retains its identity whether generating $950 million or $1.2 billion.

The firm’s climb is remarkable. Polsinelli occupied the No. 113 spot in the Am Law revenue rankings in 2013.

Today, they sit firmly within the top tier. They built this growth through systematic lateral hiring, data center practice development, and rising midmarket deal flow. They avoided high-risk, volatile mega-mergers.

What Polsinelli Is Known For

Polsinelli concentrates its primary resources on six core market sectors:

• Healthcare
• Finance and Banking
• Real Estate Development
• Technology Transactions
• Private Equity
• Life Sciences

Their national healthcare department is an industry titan. Legal directories regularly cite it as one of the largest concentrations of healthcare attorneys in the United States. The practice holds top-tier national rankings from both Chambers USA and the Best Law Firms index.

Real estate serves as another pillars of strength. Polsinelli’s transactional teams have closed thousands of commercial mortgage loans across all 50 states. Their corporate and M&A practices carry a National Tier One ranking.

Their intellectual property department mirrors this immense scale. The firm describes its IP group as one of the largest full-service practices in the nation. Their patent and trademark attorneys hold more than 100 combined technical and scientific degrees.

This tech background helps them service high-end artificial intelligence and life science clients, as detailed by the Kansas City Business Journal.

Recent Lateral Hiring and Expansion Strategy

Polsinelli’s modern expansion strategy relies on targeted lateral poaching. They focus heavily on expanding their private equity and healthcare benches in major business hubs like Chicago and South Florida.

The firm added high-profile shareholders in Chicago. Private equity M&A heavyweight Kevin Uhler joined the firm from Freshfields. Corporate shareholder Christian Fabian moved to the firm from Honigman, according to tracking data from Bloomberg Law.

On the real estate transactional side, Philip Piecuch joined the Chicago office from Katten Muchin Rosenman.

The firm also builds out its healthcare M&A bench nationally. Jonathan D. Salm joined Polsinelli’s Fort Lauderdale office as a healthcare M&A shareholder.

Firm leadership notes that these hires strengthen their ability to handle complex medical transactions nationwide. This practice-specific recruiting engine drives their financial growth.

Polsinelli In The News: A Current Legal Dispute

Polsinelli’s recent media coverage does not focus entirely on financial success. The firm currently faces high-stakes legal challenges in federal court.

Medical device manufacturers Choice Spine LLC and Zavation Medical Products LLC have filed lawsuits against the firm, according to reports from Law360.

The plaintiffs filed bad-faith patent infringement lawsuits in Tennessee and Mississippi federal courts.

The suits name Polsinelli, two of its attorneys, and their longtime client, Missouri-based inventor Dr. Roger P. Jackson. The medical device companies accuse Polsinelli and Dr. Jackson of conspiring to assert invalid or expired spinal fixation patents for financial gain.

The dispute escalated further. The medical device companies filed formal motions to disqualify Polsinelli from representing Dr. Jackson in these actions.

The plaintiffs argue that because Polsinelli and its individual attorneys are co-defendants in the malpractice and bad-faith suits, a conflict of interest exists. They claim the firm and the doctor hold diverging liabilities that legally bar continued representation.

Polsinelli and Dr. Jackson filed motions to dismiss the actions. They argue that state-level bad-faith patent statutes do not apply to commercial manufacturers and distributors. The federal courts have not issued final rulings on the dismissal or the disqualification requests.

Our Verdict On Polsinelli

Polsinelli represents an impressive story of scale. They successfully transformed a regional Missouri practice into a dominant national player. They achieved this through practice diversity, data center market capitalization, and aggressive partner recruiting.

However, immense scale brings serious litigation exposure. The pending bad-faith patent lawsuits and disqualification motions require close monitoring. The outcomes could impact their intellectual property litigation reputation moving forward.
