Mark Sandvoss is a licensed clinical social worker (LCSW) practicing in Florida with 30 years of experience in the behavioral health field. He has worked with people facing a wide range of concerns, including stress, anxiety, addictions, anger, self-esteem difficulties, depression, relationship and family issues, trauma and abuse, grief, sleep problems, parenting challenges, career transitions, bipolar disorder, and ADHD.

His counseling style is warm and interactive, grounded in respect, sensitivity, and compassion. He avoids stigmatizing labels and focuses on each person’s strengths and capacity for growth. Mark blends client-centered listening with practical tools drawn from cognitive behavioral and existential approaches, and he incorporates mindfulness where it supports coping and self-awareness. This combination helps him tailor treatment to the individual rather than applying a one-size-fits-all method.

He works collaboratively to identify meaningful goals and to design a treatment plan that matches each person’s needs and values. Seeking change requires courage, and Mark aims to support and empower people at every step of that process. He is accepting new clients in Florida and brings decades of experience to help people navigate life’s challenges.

Therapeutic Approaches and Online Care

Mark Sandvoss uses client-centered therapy to create a supportive space where the person's own goals and values guide the work. This approach emphasizes empathetic listening and collaboration, helping people explore what matters most and build on their strengths. Cognitive Behavioral Therapy, or CBT, offers practical strategies to identify and change unhelpful thinking and behavior patterns, which can be especially useful for anxiety, depression, and stress-related concerns. Existential therapy helps people examine meaning, responsibility, and life choices when facing transitions, grief, or questions about purpose. It encourages reflection and personal responsibility while acknowledging life’s uncertainties.

Choosing the right approach is part of the therapeutic process. Mark works collaboratively with each person to determine which methods fit their needs, goals, and preferences, and he adapts techniques over time as progress unfolds. The collaboration helps ensure therapy feels relevant and effective for the individual.

Online therapy offers flexible options for connecting, including video calls, phone sessions, live chat, or text-based messaging. These formats make it easier to fit sessions into busy schedules and to access consistent support from a licensed professional without geographic barriers within the therapist’s service area.
