Entering the field of mediation felt like “coming home,” and she feels fortunate to work at what she loves – building connections, and helping people be seen, heard, and understood.  In her free time, Crystal enjoys singing with others, playing board games, and volunteering and connecting at the Norwood Food Pantry. 

Halee Burg

Halee helps clients become unstuck. She supports clients in having the hard conversations – conversations to discuss the topics on which they disagree; conversations to share and better understand each other’s perspectives; conversations to identify the issues and goals most important to them; and conversations to brainstorm and evaluate options for resolving their deepest concerns.

Halee provides divorce and post-divorce mediation, marital mediation, and mediation with cohabiting and/or unmarried couples. Halee also supports adult families, siblings and their parents, as they work through the challenges of aging. And Halee assists business partners, friends, co-workers and/or or other parties in tackling difficult conversations. Halee encourages parties to create thoughtful, durable, comprehensive agreements that work for each person at the table, and that may also consider absent “stakeholders” – those who may be impacted by the parties’ decisions but are unable to participate.


A former practicing attorney who now focuses solely on mediation, to give back and help ensure broader access to mediation, Halee participates in community and court mediations through a number of greater Boston community mediation programs. 

As an active member of the Massachusetts Council on Family Mediation, the Academy of Professional Family Mediators, the National Association of Divorce Professionals, and the New England Association for Conflict Resolution, Halee continually expands her knowledge of the field, regularly participates in dialogues with colleagues about best practices and approaches, and develops relationships with professionals in related fields whose expertise helps support clients as they work to make informed decisions.

 Halee has authored a number of articles that have been published on mediation websites, on topics ranging from family mediation to cohabitation.  For your convenience, several of these articles may be found at https://www.mediate.com/author/Halee-Burg/1513 .

A graduate of the University of Rochester (BA, Psychology, summa cum laude) and the Boalt Hall School of Law at the University of California, Berkeley (J.D), Halee discovered she also enjoyed being on the other side of instruction, and regularly teaches adult education classes regarding divorce in Massachusetts.

 When not helping people become unstuck, Halee keeps busy pursuing her other passions – photographing beautiful landscapes, getting lost in a good novel, traveling, cooking, golfing, or spending special time with friends and family.

Arline Kardasis is a mediator, trainer, conflict coach and co-founder of Agreement Resources, LLC and Elder Decisions®.  Her adult family mediation and conflict coaching practice focuses on decision-making regarding aging parents, sibling communication, shared real estate and vacation properties, personal property distribution, and family businesses matters, including succession planning.

Beyond her work with adult family members, Arline provides mediation and conflict coaching around a variety of other matters, including business partnership disputes, and divorce, post-divorce and parenting plans.


Arline designs and delivers trainings for mediators, lawyers, social workers, eldercare professionals and public audiences.  She has presented workshops and seminars around the United States on the use of mediation for resolving adult family disputes – and participants have traveled to Massachusetts to attend these programs from more than 20 states and from Germany, the UK, Switzerland, Canada, New Zealand and Australia.

As a thought leader in the field of elder and adult family mediation, she has been invited to speak at numerous programs and to a variety of organizations, including the Harvard Law School Program on Negotiation, the Sino-U.S. Judicial Mediation Exchange Program, The American Bar Association, the National Association of Professional Geriatric Care Managers, and the National Academy of Elder Law Attorneys (NAELA).

Arline came to mediation in 2001 after 20 years as a small business owner.  During that time, she facilitated agreements among fellow members of a national business group, where she served as President.  After the sale of her business, it was that very satisfying work as a conflict-resolver that led her to enthusiastically pursue a “next chapter” in mediation, where she finds it an honor and a gratifying challenge mediate difficult and essential decisions.

 At home, Arline enjoys time with her husband and their two West Highland White Terriers, and regularly finds time for her other interests on the tennis court and on the pottery wheel.
