Stephanie Mastroantonio, LCSW - Therapist in Colorado

About Stephanie

Stephanie Mastroantonio is a licensed clinical social worker with nine years of experience in Colorado. She focuses on helping people manage life changes, workplace stress, and the emotional fallout from family-of-origin and attachment concerns. Her work often centers on building self-compassion and clearer communication skills.

Stephanie uses straightforward talk and practical exercises to help people move forward. Sessions focus on what matters most right now, whether that is coping with a mood diagnosis, improving sleep, or sorting out parenting stress.

Background and approach

She aims to create an empathetic space where people can name hard feelings like guilt, shame, or burnout and take small steps toward change. Her practice draws on Attachment-Based Therapy to look at how early relationships shape current patterns.

She also uses Acceptance and Commitment Therapy to help people clarify values and take committed action, and Cognitive Behavioral Therapy to address unhelpful thoughts and behaviors. These tools are selected to match each person’s needs rather than as a one-size-fits-all plan. Stephanie pays attention to cultural background and the stresses caregivers and women often carry.

She works with people dealing with adoption and foster care questions, caregiver strain, career transitions, and relationship communication problems. Her approach is respectful, direct, and focused on achievable goals. People who want practical skill-building and a supportive listener may find her style a good fit.

She guides clients through concrete steps while keeping bigger life goals in view.

Online support

How attachment work and practical therapies fit online

Attachment-Based Therapy looks at how early relationships shape current patterns. Online sessions can help people notice those patterns and practice new ways of relating in day-to-day life. Acceptance and Commitment Therapy, or ACT, focuses on clarifying values and taking committed steps toward them while learning to accept difficult feelings. That approach is useful for people managing mood conditions, career changes, or caregiving stress. Client-Centered Therapy emphasizes a respectful, nonjudgmental conversation where the person sets the pace and goals.

Choosing the right approach is a team effort. The therapist will discuss preferences, previous therapy experiences, and current goals to choose or combine approaches that make sense. That work unfolds collaboratively, with regular check-ins to adjust methods as needed.

Online therapy offers flexibility through video calls, phone sessions, live chat, or text-based messaging. Video sessions allow visual cues and a deeper conversational flow. Phone sessions can be easier when bandwidth is limited or a shorter check-in is needed. Live chat and text messaging are useful for quick skill practice, ongoing coaching, or when writing helps a person process thoughts. These options help people fit therapy into busy lives and stay connected across different schedules.
