Biography
Hal’s passion for the law stems from his admiration for his father, Robert Koelsch. Growing up, Hal saw firsthand the meaningful difference the right attorney could make in the lives of clients and their families. When Robert Koelsch unexpectedly passed away during Hal’s senior year of college, Hal chose to honor his father’s memory by following in his footsteps and pursuing a legal career.

His experience includes matters involving breach of contract, breach of fiduciary duty, tortious interference, trade secret misappropriation, shareholder disputes, bankruptcy collection matters, intellectual property rights, deceptive trade practices, declaratory judgments, wrongful termination, personal injury, and statutory and common-law fraud.
In addition to his litigation practice, Hal has assisted sophisticated business clients with transactional and regulatory matters, including contract review, intellectual property assignment and licensing, and pre-litigation dispute resolution. He has also advised clients on compliance issues involving federal and state regulations, including USERRA compliance and PACE financing requirements.
