About Allyssa
Dr. Allyssa Mattes is a licensed psychologist practicing in Indiana. She draws on six years of clinical experience to help people manage stress, anxiety, depression, and related concerns.
Dr. Mattes focuses on practical strategies that fit into daily life rather than abstract theory. Her approach blends cognitive-behavioral techniques with mindfulness and acceptance-based ideas.
Sessions often include skill practice for managing worry, mood, and attention. She works with clients on organization and executive function challenges linked to ADHD.
Background and approach
Dr. Mattes pays attention to how health and brain injury affect thinking and mood. That means she will consider factors like chronic pain, traumatic brain injury, or other medical issues when planning support.
She also addresses caregiver stress and isolation that can follow long-term illness. Parents who feel overwhelmed can get help sorting priorities, building routines, and improving communication. People struggling with social anxiety, panic, low self-esteem, or motivation can expect concrete tools and step-by-step plans to try between sessions.
She values a collaborative relationship where the client’s experience guides treatment choices. Dr. Mattes explains options plainly and checks in about what is or isn’t working.
Her practice emphasizes steady progress and realistic next steps.
How these approaches translate to online care
Acceptance and Commitment Therapy (ACT) focuses on noticing difficult thoughts without getting stuck in them and choosing actions that align with personal values; it often helps with anxiety, low mood, and life direction. Cognitive Behavioral Therapy (CBT) teaches practical techniques to spot unhelpful thinking patterns and test them with real-life experiments, which is useful for panic, social anxiety, and worry. Mindfulness therapy involves short attention and breathing practices to reduce reactivity and increase focus, supporting stress and emotional regulation.Finding the right mix of methods is part of the work. Dr. Mattes collaborates with each person to choose approaches that match their goals and daily realities. Together they try strategies, review what helps, and adjust plans based on progress and preferences.
Online formats can make consistent care easier to fit into life. Video calls allow for face-to-face interaction and live skill coaching, phone sessions can be a lower-bandwidth option for check-ins, and live chat or text-based messaging work well for brief updates, homework support, or shorter check-ins between sessions. These options offer flexibility for people juggling work, caregiving, or medical appointments while keeping therapy focused on tangible skills and steady progress.
