Bipolar disorder therapists & psychiatrists in Shreveport, LA

Hello! I have spent 4 years working in a clinical setting with all types of clients, specializing in mood disorders, PTSD, and individuals who have auditory and visual hallucinations. I try to demystify mental health and the stigmas surrounding it.

My name is Shanna McMullen, and I am a Psychiatric Mental Health Nurse Practitioner with a Master of Science in Nursing from Northwestern State University of Louisiana. I work with adults and seniors, and I bring a broad, inclusive, and genuinely creative approach to mental health care.

My clinical areas span anxiety, depression, bipolar disorder, PTSD, OCD, ADD/ADHD, panic disorders, chronic conditions, sleep disorders, stress, relationships, and family concerns. I offer dedicated support for maternal mental health — including prenatal and postpartum experiences — and I am deeply committed to affirming, knowledgeable care for LGBTQ+ individuals, including those navigating gay, lesbian, bisexual, and transgender experiences, as well as men's and women's mental health needs.

One thing that sets my practice apart: I incorporate Art Therapy as one of my therapeutic approaches — using creative expression as a powerful pathway to insight, healing, and self-discovery for clients who connect with that kind of work.

Whatever brings you here, you will be met with openness, care, and the full breadth of what I have to offer.

I am a Licensed Clinical Social Worker (LCSW) in Arizona and Louisiana with over 17 years of experience in trauma-informed psychotherapy. I earned my Master of Social Work from Tulane University in 2008 and have worked across inpatient and outpatient treatment settings, university counseling, grief and bereavement care, and trauma-focused programs. I am EMDR trained (finalizing certification) and integrate CBT, DBT, IFS-informed parts work, somatic approaches, and mindfulness-based therapies.

I specialize in complex PTSD, sexual trauma, religious and spiritual trauma, attachment wounds, ADHD, anxiety, and shame-based relational patterns. Many of the individuals I work with are high-functioning on the outside but feel lost, fragmented, or deeply self-critical on the inside.

Clients often describe me as warm, loving, affirming, and validating. I also bring a teacher’s heart into the room. I believe understanding how trauma impacts the nervous system, relationships, and even women’s biological health helps reduce shame and restore clarity. I see therapy as sacred work. You are not a diagnosis to me; you are a whole person whose nervous system learned to survive.

With over 20 years of experience in the mental health field, I am deeply committed to helping individuals and families heal, grow, and reconnect with their strengths. My work is grounded in trauma-centered therapy, recognizing that many emotional and behavioral challenges are rooted in experiences that deserve compassion, understanding, and skilled support.

Throughout my career, I have worked extensively with children, adolescents, and families, helping them navigate life transitions, relationship challenges, and the impact of trauma. I believe therapy should be a safe space where clients feel heard, valued, and empowered to move forward with confidence.
