Therapeutic approaches and online care

Dr. Mendonsa uses several evidence-informed approaches to meet different needs. Acceptance and Commitment Therapy (ACT) focuses on helping people clarify personal values, accept difficult thoughts and feelings, and commit to behavioral changes that support a meaningful life - it is often useful for anxiety, stress, and life transitions. Attachment-Based Therapy explores how early and ongoing relational patterns shape current relationships and emotional responses, helping clients improve connection, trust, and intimacy in close relationships. Cognitive Behavioral Therapy (CBT) teaches practical skills to identify and shift unhelpful thoughts and behaviors, which can be effective for depression, anxiety, and routines like sleep and stress management.

Finding the right approach is part of the therapeutic process. Dr. Mendonsa collaborates with each person to determine which methods fit their goals, values, and preferences, adjusting the plan as progress is made. This collaborative focus helps tailor work to the individual rather than following a one-size-fits-all model.

Online therapy offers flexibility and accessibility through video calls, phone sessions, live chat, or text-based messaging. These options make it easier to schedule consistent sessions around work, caregiving, or travel and allow licensed professionals and therapists to provide ongoing support without geographic constraints.
