Catherine was admitted to the Colorado bar in 2005, having already been practicing law in both Massachusetts since 1990 and New Hampshire since 1995. Catherine graduated from Michigan State University in 1983 with a dual BA in criminal justice and Spanish. Catherine studied abroad in Valencia Spain for her sophomore year of college. Upon graduation she moved to Chicago to attend a post-degree paralegal program at Roosevelt University and upon completion of the program moved to New York City where she was a supervising paralegal and manager of a law firm, supervising over 200 dental malpractice claims, construction litigation, personal injury, and maritime litigation.

Catherine went on to study law at the New England Law School in Boston Massachusetts and received her J.D. in 1989. She was involved in representation of foreign and domestic corporations being sued for allegedly defective products and then began representing plaintiffs in personal injury litigation and social security disability claims. She also developed a large domestic relations practice in both Massachusetts and New Hampshire at the request of her clients who sought representation in family law matters.

Catherine was very involved in the equine community in Massachusetts and New Hampshire and became one of several hundred attorneys in the United States who specialize in Equine Law representing horse owners, racetracks, show barns, breeders and trainers, and other service providers associated with the equine industry.

Catherine relocated to Colorado with her husband in 2005, continuing to focus on the representation of clients in family law matters including divorce, allocation of parental rights, custody, property division, post decree modifications of parenting time, maintenance and child support, adoptions, stepparent adoptions, relocation matters, grandparent rights, preparation of premarital and post nuptial agreements. Catherine recognized the benefits of mediation to parties in family law matters, so participated in a 40 hour course to become a family law mediator. She now devotes a significant portion of her practice to the mediation and arbitration of family law cases.

Catherine has now joined Bradley Devitt Haas & Watkins, P.C. to continue representing clients in family matters and mediation for parties seeking resolution of family law issues.

When not in the office, Catherine is a rewards based dog trainer assisting people with understanding canine behavior and training for more desirable behaviors from their canine companions. She also trained rescue dogs for many years with the Rocky Mountain Cocker Rescue to help ensure successful adoptions for cocker spaniels.
