Warren Goldenberg, a partner at Hahn Loeser’s Cleveland office, has more than 35 years of experience as a business law attorney. Warren has extensive experience in mergers and acquisitions, debt and equity financing, technology transfer and commercialization, clinical trials, financial restructuring, joint ventures and strategic alliances, licensing and distribution agreements, entity formation, shareholder disputes, and stock option and restricted stock plans. Warren’s merger and acquisition practice focuses on technology companies and healthcare providers.
Warren’s law practice focuses on technology and healthcare companies and technology transactions, particularly in the life sciences, information technology and materials industries. He has extensive experience representing startup companies, universities and Fortune 500 companies. Warren’s experience with technology companies dates back to the early 1990s when he represented U.S. Biochemical Corp., including the spinoff of Ribozyme Pharmaceuticals, which ultimately went public. Warren oversaw the sale of USB to Amersham Life Sciences.
In addition to practicing law, Warren has served as a startup executive for four life sciences companies. Warren is currently the COO of KeborMed Inc. (www.kebormed.com), which is a Platform-as-a-Service for cloud connected medical devices. KeborMed is an early revenue stage company which has a strategic marketing alliance with Ximedica and is working on a clinical study with University Hospitals of Cleveland.
From 2010 to 2015, he served as the part-time CEO of Fluence Therapeutics Inc. in Akron, Ohio.

From 2006 to 2009, Warren served as part-time CEO of CardioInsight Technologies Inc., a Case Western Reserve University/University Hospitals spin-off, in Cleveland. CardioInsight is commercializing electrocardiographic imaging, which is used to guide ablation therapy for atrial fibrillation and other arrhythmias. (CardioInsight was sold to Medtronic in June 2015 for $93 million, plus an earnout.) Under his leadership, the company closed a Series A venture capital financing and raised grant funding from the Global Cardiovascular Innovation Center. It also grew to seven employees, initiated clinical trials and hired a full-time CEO in connection with a Series B financing.
Warren formed Imalux Corp. in Cleveland and managed the company from 1996 to 2001. Imalux commercialized optical coherence tomography imaging technology developed at the Russian Academy of Sciences for catheter-based imaging of epithelial tissues.
