Our current and past life circumstances can often leave us with feelings of stress, anxiety, and sadness. These emotions can be confusing and difficult to manage and process. My goal is to come alongside clients to reach personal goals, using warmth, understanding, and acceptance. I will work with you, with you in the driver’s seat, to set goals, explore and gain understanding of yourself, process your emotions in a safe space, reframe negative beliefs about yourself, and find solutions that work for you. I enjoy working with clients with a variety of concerns including general anxiety, depression, trauma, and relationship issues.

Welcome! I am a health psychologist who is interested in helping people reach their maximum potential in their physical, mental, and spiritual health. I believe that counseling can promote self-efficacy, healing, peace, hope, and a sense of purpose. I believe that individuals are created wonderfully in body, mind, and spirit. In order to reach full potential of health, each domain must be addressed for whole body wellness. I practice with the intent of finding natural solutions to wellness.
I have been in private practice for six years and my rich background in counseling includes over seventeen years as a school counselor in elementary, middle and high school. I enjoy working with children, teens and adults on pursuing treatment goals for counseling using positive solutions towards improved mental health. I am certified in EMDR therapy and I am a trauma informed therapist who also has been trained in Acceleration Resolution Therapy (ART) and Progressive Counting.
