Counseling and therapy are generally two synonymous terms as they can be interchanged. A therapist can provide counseling and psychotherapy. However, a person who counsels called a counselor will depend on the degree he or she has received. Therapy involves a more difficult task to do compared to counseling. So the people conducting that can be psychiatrists, psychologists, or social workers.

This is because they see the therapist and client as equal partners rather than as an expert treating a patient.
