Hello, I am a licensed professional counselor (LPC) serving the state of Colorado. I earned my Clinical Mental Health Counseling Masters degree from Regis University. I look forward to empowering you to build resilience, cultivate joy and peace throughout your everyday life and collaborate with you on your mental health goals.
I work primarily with adults experiencing substance use, trauma, depression, and anxiety. I have a Masters Degree in Clinical Psychology with 9 years of experience in private practice, inpatient substance use clinics, and community based mental health centers.
I am a clinical social worker/psychotherapist with 15 years of experience working in various mental healthcare settings. My post graduate training has primarily focused in the areas of trauma (developmental as well as medical) as well as perinatal mental health.
I have spent years in the field working in various agencies including, non profits, residential treatment centers, criminal justice, outpatient care, and schools. I am a Licensed Clinical Social Worker, a Licensed Addictions Counselor, and an Approved Clinical Supervisor providing guidance and support to other mental health professionals in the field. I am most effective with teens and young adults who are navigating their way through some of the most challenging experiences.
I'm Nicole Shelton, a double board-certified Psychiatric-Mental Health and Family Nurse Practitioner (APRN, PMHNP, FNP). My experience in ICU and the ER informs my holistic approach to care. I specialize in treating anxiety, depression, substance use, and trauma across the lifespan. As a military wife and mother, I emphasize lifestyle balance, encouraging patients to integrate nutrition and exercise. I am dedicated to breaking mental health stigma and advocating for veterans and those impacted by trauma, ensuring you feel seen, supported, and empowered on your journey.
I am excited to work with folks 12+ who don't want therapy to feel like a doctor's office. I have experience working with anxiety, low self-esteem, disconnection, and trauma, as well as folks navigating difficult diagnoses and changing life circumstances that leave them feeling stuck, afraid, or alone.
I am a Clinical Mental Health Therapist with over 16 years of experience working with children, adolescents, adults and families in community mental health, educational and private practice settings. Prior to that, I spent 20 years in pastoral ministry. I completed my Masters in Counseling Psychology in 2008 from Northwestern Oklahoma State University, and soon after moved to Northwest New Mexico/Southwest Colorado. My professional experience includes: Administrator of a Residential Treatment Center, Clinical Administrator for Children's Behavioral Health, Student Assistance Coordinator for a school district, Visiting Professor at a School of Social Work, Private Practice, Outpatient Clinical Manager, Health Services Coordinator for a school district, and Integrated Behavioral Health Provider in a family medical practice setting. In addition to working with high risk/high needs children and adolescents, I work primarily with trauma as well as anxiety and depression. I also serve as a Certified First Responder Counselor.
There comes a time in everyone's life when we need support.
Are you sick and tired of trying to manage this alone? You wake up to another difficult day and wonder how you will cope. Anxiety and dread are becoming your best friends. But they don't have to be. You are here because you are ready for change and I am here because I can help you feel better.
