Background and approach
He has written and published articles in journals, books, and monographs. He is licensed in Texas as an LMFT, Licensed Marriage and Family Therapist, and an LPC, Licensed Professional Counselor. In sessions he aims to build a calm, nonjudgmental space where people can speak openly about stress and anxiety.
He uses plain language and practical steps so people can try changes between sessions. He encourages small, manageable goals rather than big leaps. Dashiel helps people who face addictions, trauma and abuse, depression, relationship and intimacy concerns, coping with life changes, and ADHD.
He also has an additional focus on working with intellectual disability related challenges. He offers multiple ways to connect, including video calls, phone sessions, live chat, and text messaging. Signing up starts with a short matching questionnaire and then scheduling is arranged based on therapist availability.
Evidence-based approaches and online care
Dashiel draws on well-established, evidence-based therapeutic techniques that focus on changing unhelpful thinking and behavior. One common approach helps people notice and reframe anxious thoughts, then test new ways of acting to reduce worry and avoidance. This method is useful for everyday anxiety, stress, and worry.He also uses approaches aimed at coping with trauma and addiction by teaching grounding skills, emotion regulation, and step-by-step behavior changes. These tools help people manage intense feelings, reduce urges, and rebuild routines after difficult experiences.
Choosing the right approach is a collaborative process. He will work with each person to identify goals and preferences, then adapt methods as therapy progresses. The plan is adjusted over time so it fits the client's needs and life situation.
Online sessions are offered by video call, phone, live chat, or text messaging to provide flexibility. Video works well for regular weekly sessions and face-to-face conversation. Phone can fit a quick check-in or when bandwidth is limited. Live chat and text are useful for brief updates, check-ins between sessions, or when messaging fits a busy day. These formats make it easier to fit therapy into work, family life, and other routines.
