In addition to ensuring the best litigation outcomes for clients, he works with many different groups within a business to develop processes surrounding risk avoidance and assessment. Michael is highly familiar with the Occupational Safety & Health Administration (OSHA), the U.S. Environmental Protection Agency (EPA), and the Department of Environmental Protection (DEP) authorities. He has also handled coverage-related litigation including claims of breach of contract and bad faith relative to commercial general liability insurance, and environmental insurance policies.

Michael is a graduate of Allegheny College and Duquesne University School of Law. “I am excited to join Tucker Arensberg,” said Michael. “The firm has a strong reputation for excellence in litigation, and I look forward to working with the team to represent clients in complex and challenging cases.”

She has a proven track record of success in the courtroom. She is also skilled in fact investigation and development and provides clients with analyses and advice concerning issues and risk assessments, as well as strategies and best practices for litigation.

“I am thrilled to be a part of the Tucker Arensberg team and join in their tradition of quality representation in the courtroom,” Kristy said. “I look forward to working with my new colleagues to help clients achieve their legal goals.” Kristy obtained a Bachelor of Arts degree in political science from Allegheny College. She went on to earn her Juris Doctor from Duquesne University School of Law.

Daniel R. Michelmore’s experience includes a diverse range of civil litigation matters in both state and federal courts and at both the trial court and appellate levels. Daniel has represented major electric utilities, motor carriers, and construction, cosmetic, and other companies in a myriad of litigation matters involving commercial disputes, contractual indemnity and insurance coverage issues, labor and employment matters, toxic exposure and environmental contamination claims, design and manufacturing defect cases, and the defense of serious personal injury and wrongful death claims.

Daniel received his Bachelor of Arts degree in International Studies from Kenyon College and his law degree from Washington University School of Law in St. Louis. “I am honored to be joining the Tucker Arensberg team,” said Daniel. “I am confident that I will learn a great deal from my new colleagues and that I will be able to make a significant contribution to the firm’s success.”
