John Zoller’s practice of family law began in 1984 as an intern for an Ohio Legal Aid program. Although sometimes shared with representation of hospitals and health insurance companies, John’s time has included the practice of family law ever since. Teaching family law at the college level, delivering CLE presentations and serving as the Ohio representative for Family Law Software all contribute to John’s expertise in this challenging practice area. His focus on non-adversarial processes began in 1991 with training to become a Certified Family Mediator and continued in 2001 with the addition of training in the Collaborative Practice of family law. John’s practice has been limited to family law matters since 2012. Zoller | Biacsi celebrated its 25th Anniversary in October 2018 and continues to thrive with a concentration in non-adversarial family law matters.
