Dr. Allyssa Mattes is a clinical psychologist practicing in Indiana. She has six years of professional experience and works with people facing stress, anxiety, depression, ADHD, and concerns about parenting and self-esteem.

Her approach blends clear, practical tools with attention to personal goals. She often uses Cognitive Behavioral Therapy, mindfulness techniques, and client-centered methods to help people change unhelpful thinking and build routines that work for daily life. Sessions focus on what a person wants to do differently and on small steps to get there.

Dr. Mattes draws on experience with neurological and health-related issues when those factors are part of the picture. She also addresses social isolation, motivation, communication problems, caregiver stress, chronic illness and pain, and difficulties with impulsivity or executive functioning. These topics are woven into treatment when they affect mood, behavior, or daily functioning.

Her style is collaborative. She invites people to share their perspective and helps tailor plans around individual strengths and limits. Techniques may include skills practice, behavioral experiments, and mindfulness exercises to reduce symptoms and increase coping options.

Sessions are offered in English and can be scheduled in formats that fit different needs. She holds the credential IN Psychologist 20043674A and provides care with attention to clear goals and steady progress.

CBT, ACT, and Mindfulness for online care

Dr. Mattes often draws on Cognitive Behavioral Therapy to help people identify and change unhelpful thought patterns and behaviors. CBT is practical and problem-focused, which can help with anxiety, mood issues, panic, and daily routines that feel out of control.

She also uses Acceptance and Commitment Therapy to help people clarify values and take action even when uncomfortable thoughts or feelings are present. ACT can be useful for facing chronic stress, caregiver strain, and long-term health challenges. Mindfulness Therapy is used alongside these methods to build attention and reduce reactivity, supporting calm and better decision making in stressful moments.

Finding the right approach is a shared process. She will talk with each person about goals, preferences, and what has or hasn't helped before, then recommend approaches to try together. Adjustments are made over time based on progress and feedback.

Online sessions are offered by video calls, phone sessions, live chat, or text-based messaging. Video helps when visual cues and face-to-face interaction matter, phone works well for lower bandwidth or quick check-ins, and messaging fits brief updates or ongoing support between sessions. These options make it easier to schedule therapy around work, caregiving, or medical needs while keeping focus on practical skills and steady progress.
