About Me

Jenna works with individuals ages 16+ experiencing a wide range of mental health concerns. She specializes in treating trauma, OCD, and eating disorders and has a special interest in working with clients who are struggling with issues of overcontrol and self-worth. As an experienced client herself, Jenna believes everyone can benefit from the insight and personal growth therapy brings and strives to offer this to her clients with her down-to-earth approach. Her goal as a therapist is to provide clients with a space to be truly understood and develop tools to better navigate their thoughts and emotions. Throughout the therapy process, she works collaboratively with her clients to set and achieve practical goals that are realistic for their lives right now.
