Katherine W. Schill joined LLG after over 20 years’ practice, first at an AmLaw 200 national law firm and then a global company focused on smart, healthy buildings.  She helps clients meet their goals and protect their interests by providing intelligent, practical advice on a wide range of issues.

Kathy has litigated cases large and small, bringing the same level of detail-oriented advocacy to each one.  Taking cases to trial in multiple different venues has taught her how to think quickly on her feet, relate well to both judges and juries, and develop the most persuasive cases possible.  Her writing skills are second to none and many find her first drafts to be final.

Her passion for client service drives Kathy to find the best solution for every situation she encounters and to achieve that solution through effective written and oral advocacy.
