How Allyssa works
Mindfulness tools are used to help people stay grounded when emotions feel overwhelming. Dr. Mattes has six years of professional experience.
During that time she has worked with concerns such as social anxiety, panic attacks, low self-esteem, and motivation struggles. She also supports people facing parenting stress, caregiver strain, chronic illness or pain, and issues linked to autism or intellectual disability. In sessions she focuses on practical skills that can be tried between meetings.
Therapy may include goal-setting, problem-solving, behavior experiments, and simple mindfulness practices. She emphasizes collaboration and respects each person's knowledge about their own life. People can expect a straightforward plan tailored to their needs.
The work is aimed at improving everyday functioning, reducing distress, and building clearer coping options for common challenges.

Online support options
Approaches that translate well to online therapy
Acceptance and Commitment Therapy helps people notice difficult thoughts and feelings without getting stuck, then choose actions that match their values. It can be useful for anxiety, depression, and finding direction when life feels overwhelming. Cognitive Behavioral Therapy focuses on identifying and changing unhelpful thinking and behavior patterns, often using short exercises and between-session practice to reduce symptoms like panic or low mood. Client-Centered Therapy prioritizes an empathic, nonjudgmental relationship so people feel heard while they work on goals.Finding the right approach is part of the process. The therapist will collaborate with each person to choose which methods fit best for their goals, preferences, and daily life. That may mean combining techniques, trying something for a few sessions, and adjusting the plan based on what helps.
Online formats include video calls, phone sessions, live chat, and text-based messaging, offering flexibility for different schedules and needs. Video calls let people work face-to-face when useful, phone sessions use less bandwidth, and chat or messaging can fit brief check-ins or ongoing support between meetings. These options make it easier to access consistent care and to use therapy tools in real-world moments.
