Background and Experience

Penny is a Psychiatric Mental Health Nurse Practitioner seeing clients on an outpatient basis. She previously worked in various areas of nursing, including women’s health, diabetic education, trauma, adolescent residential care, disaster relief (team leader with Volunteer Medics Worldwide and The Bridge Church Network). and as a faith-based counselor.

As a Board Certified PMHNP, Penny can evaluate, diagnose, treat, prescribe for, and do therapy for mental health issues in all age groups. She is currently working with adults only, while consulting with Pediatric Nurse Practitioners in rural areas.

Penny views mental health as inseparable from spiritual, emotional, and physical health. She integrates wellness and psychiatric care with faith, using therapy and education as tools for healing. She promotes holistic psychiatric care through the use of dietary measures, supplements, medical foods, alternative treatments, and Mindfulness techniques along with medicines and psychotherapy (individual and group).


Special Interests and Services

Penny approaches therapy from both an existential and cognitive behavioral view: she sees the need to ask and have answered the foundational questions of life (why am I here, what is the purpose of pain, what happens when we die?) while addressing the thoughts and behaviors that go with those questions. She is trained to do individual, family, and group therapy for everyone, but believes God has gifted her to counsel female sexual assault survivors both individually and in groups.

Penny has conducted seminars on healing sexual trauma and abuse, in conjunction with HOPE (directed by Amber McCutcheon). She has facilitated seminars on EMDR therapy and bariatric (weight loss) surgery. She has been a leader and facilitator for Conquering Addictions groups and has given continuing education lectures on PTSD, sex trafficking, and sexual assault (in conjunction with SLU and The Covering House).

She is co-founder of a ministry called Dignity: Liberia that takes medical, counseling, and educational teams to Liberia, West Africa where they work with female fistula survivors and with girls who have suffered trauma.

Penny is working on obtaining certification in Eye Movement Desensitization and Reprocessing (EMDR) therapy for trauma and MAT certification to treat opioid abuse disorder.
