Danielle Cotter,
MA, LMFT, PMH-C
Founder, Practice Owner and Licensed Marriage and Family Therapist
Works with: Adults
Available: In-office and telehealth in Minnesota
For more than 15 years, Danielle has had the privilege of sitting with people through some of life’s hardest moments—trauma, anxiety, chronic stress, mood struggles, relationships, transitions, and the seasons when you are not quite sure how you arrived here or how to move forward.
Danielle believes healing happens in many ways and sometimes takes more than words. Her work blends EMDR, nervous system-informed therapy, body-based and experiential approaches, mindfulness, Acceptance and Commitment Therapy, and relational exploration. Together, these approaches help clients understand their stories, listen to their bodies, process experiences that feel stuck, and reconnect with themselves more deeply.
Many of Danielle’s clients are carrying more than others realize. They may be navigating long-standing trauma, women’s or perinatal mental health concerns, burnout, recovery, caregiving, high-responsibility roles, relationship patterns, or the quiet exhaustion of always being the person who holds everything together.
Danielle’s role is not to fix you or tell you who to become. It is to walk alongside you as you make sense of your experiences, feel more grounded in your body, strengthen your connection with yourself and others, and create a life that feels more authentic and aligned.
Therapy with Danielle is warm, relational, compassionate, and collaborative. Sessions make space for difficult experiences while also recognizing your strengths, resilience, creativity, and the parts of you that may have been waiting to be understood again.
In addition to her clinical work, Danielle is the founder of C3+ Supervision Academy. She provides individual and group supervision, supervision retreats, consultation, and professional development for emerging therapists who want to become confident, thoughtful, connected clinicians.

Kate Tande
Clinical Intern
Clinical Intern
Works with: Teens and adults
Available: Add in-office, telehealth, or both
​
Kate is a Clinical Mental Health Counseling intern who brings empathy, authenticity, and respect for each person’s unique story. Her background as a teacher, small business owner, and parent has shaped Kate's ability to connect with people from many walks of life and create spaces where they feel seen and supported. Kate believes meaningful change happens when we engage the whole person—mind, body, emotions, and lived experience—and she draws on approaches that help clients connect with personal identity, internal safety, and self‑trust. Kate strives to offer a grounded, nonjudgmental presence that blends warmth and structure, and she is dedicated to creating a safe, supportive therapeutic environment where clients can explore challenges, develop new insight and skills, and move toward lasting change.
​
In addition to individual wellness, Kate's work is grounded in a passion for prevention. She believes helping clients build awareness and skills that lead to healthier, more meaningful living fosters the capacity to make thoughtful choices and nurture more connected relationships. When individuals grow in these ways, it strengthens their families and communities and positively impacts the well-being of future generations. Kate also believes that learning to navigate distress and uncertainty is a necessary part of healthy living, and that cultivating one’s ability to meet life’s challenges with self-compassion and flexibility supports lasting growth.
​
Kate plans to continue developing her training in trauma-focused modalities and mind-body approaches with emerging interests in better supporting neurodivergent clients, individuals recovering from high‑control environments, those who have experienced complex developmental trauma, and those living with chronic health challenges.

One Shared Commitment to Whole-Person Care
Courage
Healing often begins with the courage to acknowledge that something is not working, ask for support, or gently turn toward experiences that feel difficult or uncertain.

Connection
Meaningful change does not happen in isolation. It grows through safe relationships—with ourselves, our bodies, our providers, and the people who walk alongside us.
Creativity
There is no single path to healing. Creativity allows us to explore new perspectives, combine different forms of support, and develop care that fits the individual rather than expecting the individual to fit a predetermined plan.
