Therapeutic Approaches and Online Care

Dr. Allyssa Mattes draws on cognitive behavioral therapy and acceptance and commitment therapy alongside mindfulness-informed techniques to support clients in online sessions. Cognitive behavioral therapy helps people identify and change unhelpful thoughts and behaviors that contribute to anxiety, depression, and stress, offering practical strategies for managing symptoms and improving daily functioning. Acceptance and commitment therapy emphasizes values-guided action and accepting difficult thoughts and feelings while building psychological flexibility - an approach that can be useful for chronic stress, avoidance, and motivation challenges. Mindfulness-informed techniques focus on present-moment awareness and skills for grounding attention, which can reduce reactivity and support emotional regulation.

Finding the right approach is part of the therapeutic process, and Dr. Mattes collaborates with each person to determine which methods best fit their needs, goals, and preferences. This collaborative stance helps tailor treatment over time so that therapy remains aligned with what matters to the client.

Online therapy with Dr. Mattes is available via video calls, phone sessions, live chat, and text-based messaging, offering flexibility for different schedules and communication styles. These options make it easier to access consistent care from licensed professionals and therapists without the need to travel, supporting continuity of treatment across life transitions and busy routines.
