Leah is a Licensed Professional Counselor and Nationally Certified Counselor who obtained her masters’ degree from Oral Roberts University in 2022. Since graduating, Leah has served as a mental health counselor at Hume Fogg High School with the STARS program. STARS is a school-based service offering support to students dealing with various challenges like trauma, violence, PTSD, substance abuse, depression, grief and loss, and bullying. Previously she served as a part-time therapist working with children at Safe Haven Trauma. She is excited to join the NNPA team as a TMS technician and Group Therapy Co-Leader while she continues her work with STARS.

Leah’s approach to counseling is hopeful, creative, and collaborative. While she works with people of all ages, adolescents and young adults are her jam. She operates from a non-judgmental, playful, curious, and empathetic posture, seeking to hear her client’s story and understand without assumption. Working with individuals and families who have experienced unsafe physical and/or emotional environments, establishing trust and felt safety is incredibly important. Leah offers an open space for her clients to come as they are and take the time needed to feel comfortable. No matter what has happened in the past or what you may be facing or feeling currently, there is healing and freedom to be uncovered. In the words of Samwise Gamgee, “Where there is life, there is hope.”

One size does not fit all, and Leah works with her clients in the way best suited for how they are wired. From connecting to the outdoors, incorporating movement, art, play, “walk and talk” and giving room for creative expression, Leah provides therapy through a variety of mediums. Finding the words to express what may have happened can be profoundly meaningful but often not enough. Too this end, Leah is trained in EMDR and she finds this may be the method of choice for helping free clients who have felt “stuck” in certain patterns of thinking and living by gaining access to their inner-world that is found beyond words.

In addition to counseling (which she loves!), Leah’s happy place is outside. You can find her trail running, playing sports, doing yoga, hiking, walking – all things movement. She loves to laugh and is always here for a good pun. She is refreshed by quiet time, baking, reading, puzzling, and writing. A spot of coffee and a warm scone with a friend is one of her favorite things.
