Book a therapist or psychiatrist in Slidell, LA covered by Cigna

I am a Licensed Clinical Social Worker with over 10 years of experience supporting individuals, adolescents, young adults, and families through challenging life experiences. I understand that opening up to someone you’ve never met can feel intimidating, and my goal is to create a calm, supportive, and nonjudgmental environment where you feel safe sharing your story. I work with clients navigating anxiety, depression, trauma, complex trauma, relationship struggles, emotional overwhelm, and life transitions that can leave people feeling stuck or uncertain about how to move forward.

My experience includes working in private practice and community-based settings with adolescents and young adults who may be at risk or navigating difficult family dynamics, identity development, stress, and trauma-related challenges. I have also trained in play therapy and incorporate developmentally appropriate techniques when working with younger clients. I earned my Master’s degree in Social Work from the Tulane University School of Social Work and strongly believe the therapeutic relationship is the most important part of meaningful change. When I’m not working, I enjoy spending time with friends and family, reading, and walking my little black dog, Buddy!

Welcome. I’m glad you’re here.

Reaching out for support can feel overwhelming. I aim to create a safe, collaborative, and grounded space from the beginning. I meet clients where they are and move at a pace that feels manageable and respectful.

I work with children, adolescents, adults, couples, and families experiencing anxiety, trauma, addiction, and relationship challenges. I also specialize in complex and developmental trauma.

I support clients in integrating their spiritual and cultural values into therapy when desired and clinically appropriate. I was born in New Orleans and bring a culturally informed perspective shaped by my Latina, Indigenous, Christian, and Sephardic Jewish backgrounds.

I became a therapist because I have a deep commitment to helping people recognize and build their own strengths, especially during periods of feeling stuck, overwhelmed, or disconnected. I understand that seeking support takes courage, and I work to create a space where clients feel heard, understood, and supported throughout the process.

I earned a Master of Social Work (MSW) and PhD from Tulane University, as well as a Master of Public Health (MPH) from Tulane University’s School of Public Health and Tropical Medicine. I am a Licensed Clinical Social Worker (LCSW) in Louisiana and Texas, and a Licensed Independent Clinical Social Worker (LICSW) in Minnesota. I also hold a Licensed Addiction Counselor (LAC), Licensed Prevention Professional (LPP), and Certified Employee Assistance Professional (CEAP).

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 bring to my work both professional ( LCSW/ Social Work) training and decades of lived experience. As a first generation American who grew up on the Louisiana bayous, I have traveled widely through Europe, India and many other parts of the world immersing myself in diverse cultures, faiths, and perspectives. I am well versed in the arena of substance abuse and recovery work. I have supported people through the dying process, grief and loss; and, have helped many walk through their fears, their sense of hopelessness, despair and lack of purpose. I approach anxiety and depression holistically by focusing on the mind/ body/ spirit connection. My own journey has taught me that healing is always possible and that we are all WORKS IN PROGRESS.

Looking for someone who will truly listen? I believe everyone needs support, and I strive to be that steady presence in therapy. Clients often describe me as warm, open-minded, and easy to talk to. My goal is to create a space where you feel heard, respected, and comfortable being yourself.
