Dr. Alexander Tereshchenko is a psychotherapist & psychiatrist based in Sioux Falls, SD

Whether you're new to therapy or have tried other approaches without success, I’m here to help. My focus is on getting to the root of the issue so that our work together makes a meaningful difference from the start. If you're curious about how therapy could benefit you, let’s talk.


I help adults with anxiety, depression, trauma, relationship issues, identity struggles, loss and grief. I also specialize in working with cancer patients or those coping with medical illness. I offer medication management to those I see in regular therapy as well.

I invite you to learn more about my therapeutic philosophy or securely request an appointment. Together we can improve your future — I look forward to the journey.
