Our medical practice faced a challenging professional liability claim that threatened both our reputation and financial stability. Engaging John Zen Jackson of Greenbaum, Rowe, Smith & Davis was a pivotal decision. His five decades of experience, particularly his deep focus on healthcare litigation and administrative proceedings, were immediately evident. He demonstrated a masterful understanding of both the legal nuances and the medical standards of care involved. While his strategic counsel was invaluable—leading to a very favorable resolution—there were occasional delays in receiving email responses, likely due to his demanding caseload. His recognition as a multiple-time 'Lawyer of the Year' in medical malpractice defense is well-deserved. Mr. Jackson’s calm, authoritative presence and his firm’s resources in Iselin provided immense reassurance throughout a stressful process. We highly recommend him for any healthcare entity navigating litigated or credentialing issues.
