Mark Sandvoss, LCSW

Mark Sandvoss is a Licensed Clinical Social Worker (LCSW) in Florida with three decades of experience in behavioral health. He helps people facing stress, anxiety, depression, addictions, anger, and self-esteem concerns. He also supports those dealing with trauma, grief, relationship and intimacy challenges, sleep problems, and parenting strains.

He works in a warm, interactive way and focuses on clear, practical goals. Sessions are respectful and direct, and he avoids stigmatizing labels. He explains options plainly and helps people choose what to try next.

Mark draws on several approaches to tailor the work to each person. He uses client-centered methods to follow what matters most to the person in the room. He applies cognitive behavioral techniques to identify and change unhelpful patterns of thinking and behavior. He also brings existential and mindfulness ideas to help with meaning, values, and staying present.

Over 30 years of practice have included support for people with bipolar disorder, ADHD, compassion fatigue, codependency, and issues around fatherhood and life purpose. He also lists aging and geriatric issues among his additional focuses and can address concerns that come with later life transitions.

Mark asks new clients to set goals together and build a plan that fits their needs. To begin, prospective clients complete a short matching questionnaire and then schedule a first appointment based on his availability.

How Mark blends talk therapy and practical tools online

Client-centered therapy focuses on the client’s experience and priorities. The therapist listens closely, follows what matters most, and helps people shape goals that fit their life. Cognitive Behavioral Therapy, or CBT, looks at the link between thoughts, feelings, and behaviors and offers concrete techniques to change patterns that cause distress.

Choosing an approach is a collaborative process. The therapist will discuss options, try methods that match the client’s goals, and adjust the plan as needed. People often try a mix of approaches until they find what helps most.

Session formats are not specified in the biography, so confirm current online options before booking. Many people find online work helps fit therapy into a busy week and makes attending more consistent. Online meetings can reduce travel time, allow for shorter check-ins when needed, and make it easier to schedule sessions around work or caregiving. A practical plan is part of the work: setting goals, trying small changes between sessions, and tracking what shifts over time.
