    also not treating me as if  I was an eating disorder. They treated me like the real, whole person that I had lost sight of. They have an ability to hold nuance gently and they aren’t afraid to wade into the hardest waters, which is so much more helpful than receiving treatment that is guided by a rigid manual. There is an unbelievable amount of safety at Alsana because of this and my gratitude is crazy high!

I took, and continue to take pride in the progress I made and continue to make. Most importantly, I am now capable of self-acceptance and self-love whether I succeed, fail or anything in between.

  • Before coming to Alsana, I had never had a treatment experience in which the "how" and "why" of the eating ...

    disorder were addressed. This has proven to be essential in my treatment at Alsana and also in my daily life as a member of society. Alsana providers led me through so much illuminating self-reflection about topics that I had never before considered relevant to my treatment, recovery, or self in general. Alsana staff appreciate and treat the individual, and I felt this in and outside of therapy sessions. They always humored my random geography facts and propensity to trail glitter wherever I went. 🙂 Ultimately, my treatment experience at Alsana taught me how to be a shamelessly authentic individual, and it gave me a sense of safety to explore what it means to be myself. With so much love,
