Jim grew up in St. Louis, Missouri, and attended the prestigious St. Louis Country Day School. He took his undergraduate studies at Southern Methodist University in Dallas, Texas, earning a Bachelor of Arts Degree in Political Science and a minor degree in History.

After graduating from Southern Methodist University in 1990, Jim became involved in the political arena, successfully managing two campaigns in St. Louis County for the Prosecuting Attorney of St. Louis County. Jim then took his political skills to the nation's capital working for Congresswoman Joan Kelly Horn as her direct media director and her legislative assistant on judicial affairs.

Jim then returned to St. Louis and attended Washington University School of Law.

After graduating in 1998, he moved to Florida and worked exclusively in Family Law for four years.

Jim's family law practice consists of protections orders, paternity actions, enforcement actions, modification actions and simple to very complex dissolutions. Jim's experience encompasses contested complex financial cases (utilizing forensic accountants) and complex custody matters (including national and international relocation cases). These complex financial issues encompass business valuations, asset distributions and income analysis (including marijuana businesses). These complex custody matters encompass the full range of parental and children issues (including marijuana and alcohol issues). Further, Jim's experience includes the entire spectrum of family law litigation including, but not limited to, initial client meetings, all discovery compliance and execution, temporary orders hearings, expert witness utilization and permanent orders hearings.

In 2003, Jim returned home to St. Louis, where he continued his family law practice but also expanded into commercial litigation matters.

Jim's commercial litigation practice consists of business litigation, real estate litigation, construction law litigation and other complex civil litigation. Jim's practice consists of all aspects of complex civil litigation including, but not limited to, client meetings and exploration and development of litigation/settlement strategy, written discovery, motion practice, deposition of lay and expert witnesses, pretrial procedures, preparation of legal memorandums and trial briefs, voir dire and all aspects of trial counsel.

In 2009, Jim re-located to Boulder, Colorado, and continued to focus his practice on family law matters and commercial law matters.

Jim's practice also includes a significant focus on all aspects of mediation and arbitration and he remains in the forefront of the utilization of alternative dispute resolution techniques to resolve disputes before resorting to costly and lengthy litigation. What sets Jim apart from other lawyers is his unique expertise in the areas of family law and commercial law combined with practical solutions to legal problems that apply the right combination of creativity, legal and industrial knowledge, innovation, and commitment. Clients can rely on Jim to be approachable, responsive, efficient, and effective.
