About Mark

Mark Sandvoss is a licensed clinical social worker with three decades of experience helping people manage stress, anxiety, depression, addictions, and relationship concerns. He listens without judgment and focuses on practical steps people can try between sessions. His style is warm and interactive, and he aims to treat people with respect and compassion.

Mark blends several ways of working to meet each person's needs. He draws on existential ideas to help people find meaning and direction when life feels empty or uncertain.

Background and approach

He uses cognitive behavioral techniques to spot and change unhelpful thinking and behaviors that keep problems going. Client-centered principles guide how Mark works in sessions. He pays attention to each person's experience and builds goals together rather than imposing a plan.

Mindfulness practices are offered when breathing, grounding, or noticing the body can help reduce anxiety or improve sleep. Mark has helped people cope with trauma, grief, anger, intimacy-related concerns, and parenting strain. He also supports work on self-esteem, life purpose, compassion fatigue, and mood instability.

He has worked with long-term challenges such as bipolar mood disorder as well as situational issues like career change and caregiving for older adults. Sessions focus on clear, achievable steps and on understanding the choices people face. Mark encourages collaboration: he and the person set goals, try techniques, and adjust the plan as needed.

His approach aims to be straightforward and humane for people looking for change.

Online support

How Mark’s approaches translate to online therapy

Existential Therapy focuses on meaning, choice, and values. Online sessions allow people to talk about life direction, purpose, and loss and to reflect on tough choices in a conversational way. Client-Centered Therapy emphasizes listening and empathy; over video or phone the therapist mirrors concerns and helps people feel heard, then works with them to set goals. Cognitive Behavioral Therapy (CBT) helps identify thoughts and behaviors that keep problems going and tests small changes; it translates well to online work with homework and short experiments between sessions.

Choosing an approach is a collaborative process. The therapist will discuss goals, preferences, and practical needs and then try methods that feel right. If something isn’t working, the plan is adjusted together rather than fixed in advance.

Online formats offer flexibility and different ways to connect. Video calls are useful for deeper conversation and seeing nonverbal cues. Phone sessions require less bandwidth and can be easier to fit into a busy day. Live chat and text-based messaging are useful for brief check-ins, tracking progress, or getting support between sessions. These options make it easier to keep therapy consistent around work, caregiving, or travel.
