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

Whether you're new to therapy or returning after past attempts that didn’t quite help, I offer a space to go deeper—beyond symptoms, toward lasting change. My focus is on understanding the roots of your struggles so our work can make a meaningful and enduring difference.

I work with adults facing relationship difficulties, identity concerns, anxiety, depression, trauma, loss, and grief. I also have specialized experience supporting those living with cancer or other medical illnesses. As a psychiatrist, I can prescribe medication when it's helpful—always within the context of a thoughtful, ongoing therapeutic relationship.

If you’re curious about how therapy could support you, I invite you to explore my approach or securely request an appointment. I look forward to learning more about you and how I can help.
