If you are navigating grief, a serious illness, a cancer diagnosis, or the quiet exhaustion of caring for someone you love, I am here for the full weight of it. I also work with people moving through anxiety, depression, infertility, and major life transitions like new parenthood or a shift in your sense of self. My focus is the place where health, loss, and life change intersect, and I believe that even in the middle of the hardest experiences, people have a remarkable capacity for resilience and connection. I am affirming and welcoming of LGBTQIA+ clients.
