Casey C.R. Nielsen, BA, MHP

Chemical Health and Behavioral Health Intern


I am a Chemical Health and Behavioral Health Intern. I am completing my final year in the Co-Occurring Disorders program at Adler Graduate School, working towards my LADC and LPCC. I have a BA in Sociology and have worked in various positions in the chemical health and behavioral health fields since 2011.

I work from a person-centered, strengths-based, risk-reduction approach and incorporate a variety of techniques based on individual needs. My areas of interest include folks living with serious and persistent mental illness (SPMI), substance use disorders, process addictions, and the LGBTQIAA2S community.

I believe Alfred Alder said it well when he said this of empathy: “Seeing with the eyes of another, listening with the ears of another, and feeling with the heart of another.” For me, empathy is a big part of therapy. I will show you empathy, and I hope to help you look inward to find ways to be gentle with yourself. I look forward to working with you.

Sasha Weist, LADC

Behavioral Health Intern


I am a licensed alcohol and drug counselor (LADC) and a graduate student at the University of Minnesota, Twin Cities finishing up my degree in Integrated Behavioral Health.  I am a behavioral health intern at JustUs Health and am excited to help clients make positive changes in their lives, whatever that looks like to them. 

I enjoy working with a wide variety of clients but have the most experience working with clients in the LGBTQIA+ community. I have a professional interest in issues around depression, grief, anxiety, and co-occurring mental and chemical health issues. I come from a trauma-informed, risk reduction perspective. My approach is dependent on what each client needs, but I tend towards a combination of CBT and interpersonal therapy.

I hope our time together can be a safe place where you feel connected and heard. I think the tools for success already exist within each of my clients when they walk through the door, and our time together is about learning to access those tools most effectively.
