Both, really. Psychiatry has become more biology-oriented in recent times, but many psychiatrists (myself included) believe that some symptoms cannot be cured with medications, and instead require an understanding of unconscious workings of the mind for their resolution.
It takes a number of years to become an analyst. Some analysts were first trained as psychiatrists; others were initially social workers or psychologists. There are not a lot of analysts out there so they tend to have close-knit academic societies, and also tend to all know each other, or know of each other.
There is little quality control when it comes to finding a psychotherapist, so I often suggest that people look to the nearest psychoanalytic society in order to find a therapist-- IF one is looking for a 'psychodynamic' therapist. On the other hand, If one is looking for supportive therapy or CBT, the analytic community might not be as helpful.
