Mark Sandvoss, LCSW

Mark Sandvoss is a licensed clinical social worker (LCSW) in Florida with three decades of experience helping people manage stress, anxiety, depression, addiction, and trauma and abuse. He offers a calm, respectful style and focuses on real problems that get in the way of day-to-day life. Mark aims to help people who are struggling with grief, relationship and intimacy concerns, sleep problems, parenting strain, and sudden life changes.

In sessions he keeps the work practical and straightforward. He listens closely, helps set clear goals, and uses tools to change patterns that no longer work. He draws on cognitive behavioral ideas to notice and shift unhelpful thoughts. He also uses client-centered and existential perspectives to explore meaning and personal values.

Mark emphasizes collaboration and strengths already present in each person. He avoids labels that shame and instead helps people build coping skills for mood disorders, bipolar concerns, ADHD, and compassion fatigue. He also supports those dealing with codependency, fatherhood questions, aging issues, and finding life purpose.

Clients can expect warm, interactive sessions where progress is measured against personal goals. Mark will work with each person to shape a plan that fits their situation and priorities. He encourages small, sustainable steps alongside deeper conversations about identity and values.

With a long history in behavioral health, Mark combines practical strategies and thoughtful conversation to help people move toward a more manageable life. He invites those ready for change to begin the process together.

How Mark’s approaches translate to online work

Client-Centered Therapy focuses on listening and meeting people where they are. The therapist follows the client’s lead, reflects concerns, and helps people find their own solutions to issues like self-esteem, grief, and relationship stress.

Cognitive Behavioral Therapy (CBT) looks at the link between thoughts, feelings, and behavior. It uses specific exercises and practical tools to reduce anxiety, manage mood symptoms, and change unhelpful habits.

Existential Therapy addresses meaning, values, and the big questions that come up during life changes. It can help when someone is rethinking purpose, dealing with aging, or facing transitions.

Finding the right approach is part of the work. The therapist will collaborate with clients to choose methods that fit their goals, needs, and preferences. That might mean blending practical CBT exercises with values-focused conversation and supportive listening.

Confirm which session formats are offered before booking, since the profile does not list specific options. Online work can make scheduling easier, help fit sessions into a busy day, reduce travel time, and allow for shorter check-ins when needed. Talk with the therapist about what will best fit your routine and what methods you’d like to try.
