In 2001, Kim began her career at Hanley Center. While working on the women’s unit, she saw a need for more aftercare support, thus creating an Alumni Program that is still in place today. Kim’s joy was connecting alumni to one another and setting up Alumni Chapters across the country, along with inviting the alumni back to celebrate years of recovery on Anniversary night. It was such a rewarding time in Kim’s professional life and one that she has treasured all these years.   

In 2008, under her parent company, Got Real Recovery, Kim founded Butterfly House, one of the first FARR Certified Recovery Residences for women.  She served as Chief Executive Officer of Butterfly House until she closed the doors in late 2016.

In 2017, while working in private practice as a Psychotherapist and Interventionist, Kim was asked by a colleague if she knew anyone who would want to join an outreach team for a treatment center. Much to Kim’s own surprise, she said, “What about me?” And so began 5 years of bringing her gift of working with the addicted and their families to the outreach arena.  And yet, Kim yearned to return to direct care with the alumni and their families.

One of Kim’s mentors recognized her insatiable thirst to return to where she began. With Harmony Recovery Group ready to launch its Alumni Care Initiative, Kim is thrilled to join the team as Alumni Care Director.

Specializing in women’s issues, LGBTQ+, trauma, family, motivational intervention, and building community, Kim combines her own personal experiences along with her education and training to envision and provide a unique blend of care to individuals and families. 

A native New Yorker and long-time resident of Palm Beach County, Kim resides in Wellington with her family. As an alumna herself and woman in long-term recovery, her mantra is “It was in my heart to help a little because I was helped much.”  – Kahlil Gibran
