Anxiety and depression therapists and psychiatrists in League City, TX

Hi there! My name is Marynna Tymme Reyes-McCallister. Everyone calls me by my middle name - Tymme (Time). I have a M.Ed. in Clinical Mental Health Counseling from Lamar University. I have experience working in non-profits, schools, and private practice with children, teens, individuals, families and groups.

I know what it’s like to want change and feel unsure where to begin. That’s why I created Oh Shift-a space to pause, breathe, and start again. As a dual-certified Nurse Practitioner with over 10 years of experience, I bring clinical expertise grounded in genuine compassion. I don’t believe you’re broken, I believe you’re becoming. Your story matters, and this work is about helping you shift into the next version of yourself with clarity, confidence, and intention.

My primary goal is to provide a helping hand to clients in need. Clients will find that I am able to listen and provide helpful strategies to help navigate through whatever journey they find themselves on. Whether it be a young child, adolescent, or adult, I am able to keep them at the center of the therapeutic process and help them discover peace and purpose.

I graduated Summa Cum Laude from the University of Houston and obtained a Masters of Education in Counselor Education from the University of St. Thomas. I was an educator for 13 years including 5 as a school counselor/administrator.

As a school counselor, I have assisted students with disabilities, trauma, mood and personality disorders. I have also worked with parents who find themselves in a cycle that they feel cannot be broken. My intention is to help clients identify hurts, hang-ups, and habits that keep them from living to their full potential and work through them.

I am EMDR trained and provide trauma informed care. I have also utilized Cognitive Behavioral Therapy and various interventions from Dialectical Behavioral Therapy to treat clients with anxiety, depression, and self-harming behaviors.

Whatever it is you are facing, I am willing to listen and provide sound care. As a fellow human, I understand the needs that can arise from trauma, hurt, and misunderstanding. If you are in need of an ear to hear and a heart to care, please contact me. I am here to help.

For me, helping others has always been deeply personal. I believe every person deserves to feel heard, seen, and understood. I am a Licensed Professional Counselor with a Master of Science in Clinical Mental Health Counseling from the University of Houston–Clear Lake. I enjoy working with individuals navigating chronic pain or illness, adjustment challenges, and caregiver burnout. I bring a compassionate, collaborative approach to therapy and strive to create a space where clients feel safe, supported, and respected as we work together toward meaningful and realistic goals.

I have spent over 40 years teaching, training, and developing mental health programs for individuals from 4 to 84 find hope once again. I am a life-long learner and add at least one certificate a year to ensure clients are given multiple approaches to what they encounter. I am very honest and direct, but also understand the need for pause and reflection. You know the level of your pain and suffering. My job is to meet you where you are and lead you to the place you want to go.
