About Karriann Longtin (She/Her)

Hi, I’m Karriann Longtin, a Psychiatric Mental Health Nurse Practitioner in Illinois and I’ve been licensed as a nurse practitioner since 2008. I’m passionate about making mental health care accessible and breaking down the stigma around it. With a rich background in healthcare, I bring a holistic approach to mental health, focusing on compassionate and comprehensive care.

I’m all about creating a safe, judgment-free space where you can talk openly about your mental health. I stay updated on the latest in psychiatric care to ensure you get the best, evidence-based treatment. I craft personalized treatment plans that fit your unique needs.

Let’s work together to challenge mental health stigma and empower you to seek the help you deserve. Outside of work, you’ll find me enjoying gardening, crafting, watching anime, and listening to fiction audiobooks—especially suspenseful stories and anything with dragons and strong female characters.

See what our patients are saying about Karriann Longtin

Karriann is phenomenal. I came to her 10 months ago a mess. Her patience and ability to really hear what you're telling her? First class. 100% judgement free. She will never look at you that way either. Now, 10 months later? I can smile, I can laugh and I can feel. The days of crying all the time are gone. I highly recommend Lifestance and Karriann. If you're new at this and are just researching? Call and make an appt with her. You won't regret your decision.

I met with Karriann for the first time today after needing to switch providers. I already see someone with lifestance health for therapy and I love her. Karriann came recommended to me by my provider. Karriann took time to understand the issues I came to her with and was very informative and relatable which gave me comfort in being there. I had a great visit and feel comfortable in her care. She is very sweet and knowledgeable.

I do enjoy my therapist very much with this company. She takes time to explain and keeps things really calm and cool. She was able to get me the help and diagnosis I needed to continue on through life. I was very anxious and stressed but it turns out my anxiety was an underlying disorder that I didn't know I had. I am very thankful to lifestance and Kariann Longtin for her help with my mental health journey.

The team at lifestance have helped me so much, I was struggling with somethings and wasn't sure how to deal with them. I learned that taking care of myself and having boundaries has really changed my life. Talking with the people at Lifestance has been so helpful for me that I referred all of my family members to try Lifestance too. You don't know the difference it can make until you try it.

Staff are terrific, testing was scheduled in a reasonable time, and I was able to proceed with treatment for my AuDHD and begin counseling to deal with coping mechanisms, technological advances and apps, as well as trying different meds until I felt truly comfortable with how I felt in my daily life.

This was my first time coming in person. I absolutely love my provider, Kariann. It took me a long time to find someone who listens and makes me feel heard and understood. The office was nice and the receptionist was kind and helpful. No complaints at all.
