A consummate professional who guided our business through a critical transition

After 40 years in practice, Michael Quinlan possesses a rare depth of knowledge that was immediately apparent. Our situation involved restructuring our family-owned manufacturing business, a complex process requiring expertise in corporate law, LLCs, and partnership agreements. Mike’s background, from his Cornell law degree to his four-decade tenure at Jensen Baird, provided a foundation of trust from our first meeting. He didn't just process paperwork; he acted as a strategic advisor, patiently explaining the implications of each decision for our future operations and legacy in Portland. His recent recognition in Business Organizations and Corporate Law is well-deserved, reflecting the caliber of counsel we received. Mike’s approach is both meticulous and pragmatic, born from a genuine understanding of Maine’s business landscape, which he has been part of since returning after law school. He anticipated potential issues we hadn't considered and crafted solutions that protected all parties involved. The process was seamless, and the outcome has positioned our company for sustainable growth. For any business facing formation, restructuring, or complex corporate matters, Michael Quinlan is the attorney you want in your corner.
