Are you tired of carrying the weight of everything on your own? Ready to stop feeling stuck and start creating meaningful change? I help adults navigate anxiety, depression, trauma, grief, relationship and intimacy concerns, family challenges, OCD, health-related stress, sexual identity exploration, seasonal affective disorder, work stress, and major life transitions. You deserve a space where you feel genuinely heard, understood, and supported. Together, we'll uncover what's keeping you stuck, explore new perspectives, and develop practical strategies that help you move forward with greater confidence and clarity.
Life is full of ups and downs, and I have learned from both personal and professional experience that 'suffering in silence' is not really sustainable or healthy for anyone. You deserve to feel heard and to function at your best level. I have 6 years' experience post-graduation from the University of Texas with helping folks do just that. From nonprofits, to medical clinics, to correctional facilities, to teletherapy, I have connected deeply and partnered with many clients and families to trudge through some of their darkest hours and find more validation, calmness, and acceptance. My fluency in Spanish has given me opportunities to break down walls and connect with hundreds of clients whose cultural background is different than mine. I would be honored to have the chance to see if working together is a good fit for your healing journey.
I am a board-certified Psychiatric Nurse Practitioner with 2 years of advance psychiatric practice and a total of 15 years of experience in healthcare. I specialize in evidence-based care for adults living with anxiety, depression, ADHD, stress, and life transitions, combining thoughtful medication management with practical strategies that help clients build a deeper understanding of their mental health.
In addition to my clinical practice, I am an author and whole-body wellness advocate. My book, BePurBold: A Woman's Journey to Whole Body Wellness, reflects my belief that lasting mental health is rooted in lifestyle, resilience, and whole-person well-being. My goal is to offer a supportive, non-judgmental environment where clients feel heard, valued, and active partners in their own care.
I am a licensed clinical social worker with experience in community mental health, crisis intervention, and counseling. I specialize in supporting individuals who have experienced trauma and adversity, and I approach therapy from a holistic perspective—seeing each client as a whole person within the context of their environment.
My work is rooted in being trauma-informed, nonjudgmental, and collaborative. I often integrate somatic therapy and mindfulness, recognizing that trauma is carried not only in the mind but also in the body. My goal is to create a safe, supportive space where clients can explore their experiences, build resilience, and move toward healing.
Is your experience with pregnancy, postpartum, or parenthood not going as you thought it might? Or are you finding the transition to motherhood stressful and life changing? Though it can be joyful, it can also be a vulnerable time filled with overwhelming stress, worry, sadness, or even grief. If this sounds at all like you, please know I am here to help.
Hello, and welcome. My name is Patricia Mathison, and I am a Licensed Mental Health Counselor (LMHC) dedicated to supporting individuals in navigating life’s challenges with compassion, clarity, and practical tools for growth.
I bring a strong professional background in mental health counseling, with experience working with diverse populations. My work has allowed me to support clients through concerns such as anxiety, depression, life transitions, relationship difficulties, and stress-related challenges.
I earned my Master’s in Counseling and Psychology from Lesley University, where I received comprehensive training in evidence-based therapeutic approaches. I continue to stay current in the field through ongoing professional development and training.
My areas of specialization include anxiety and depressive disorders, trauma, mood disorders, self-esteem, or relationship issues. I often draw from approaches such as Cognitive Behavioral Therapy (CBT), person-centered therapy, mindfulness-based techniques, tailoring each session to meet the unique needs and goals of the individual.
I believe therapy is a collaborative process built on trust, respect, and authenticity. My goal is to create a safe, nonjudgmental space where you feel heard and supported as you work toward meaningful change.
Whether you’re seeking support for a specific concern or looking to better understand yourself, I am here to help you move forward with confidence and resilience.
