Jillian has 12 years of experience working in the mental health field as a social worker and has her bachelors in criminal justice, with a minor in psychology. During her time working with the mentally ill and vulnerable populations, Jillian learned many conflict resolution and crisis intervention skills, which have ultimately drawn her to the field of mediation. Jillian also practices as a life coach and specializes in relationships and self-worth.

Jillian's passion for relationship health, strong communication skills, and empowerment, have created a desire to use meditation as a means to encourage peaceful dispute resolution. Jillian currently serves as a domestic mediator, in the areas of marriage, divorce, custody, guardianship, adoption, and property division. Jillian is very satisfied to be able to provide a more peaceful means of navigating divorce and other highly emotional conflicts, through mediation. Jillian's style of mediation is a narrow, facilitative approach, which means she addresses specific, measurable problems, with a neutral method, allowing her clients to dictate the outcome.

Steve Pinther - Appointed 

 I first received mediation training in the spring of 2010. At that time I had 30 years of general contracting,producing custom upper end homes in Southeastern Idaho. I also had the privilege to serve the construction industry in many professional positions. I was fortunate enough to be able to see the construction Industry from several different perspectives. I served as president of the Idaho Building Contractors Association (IBCA) and also, served as Chairman of the Idaho State Contractor Registration Board. And because of my service to the contractor board I was able to represent Idaho at the National Association of Contracting Licensing Agencies (NASCLA) and served one year as President of that organization.

My plan was to retire and help other contractors and homeowners resolve their problems. But after 10 more years of building, because people kept calling me, I had not pursued my ambition. But all was not lost during those years because I did volunteer to mediate the Small Claims cases in Fremont, Madison, and Teton county for the magistrate court. I do believe these years in small claims has aided because of the challenges and variety of cases that small claims present.

I have always looked to improve my capabilities and through the years I have been able to receive more extensive training in construction and business disputes. I have also had additional training in Elder mediation to help families resolve issues pertaining to future elder care or resolve estate disputes.I do not engage in any domestic or Child custody mediation.

My experience and training provides me with unique knowledge to be able to assist people, contractors or families in solving their needs in a professional environment.
