Exceptional and thorough care. The doc helped me navigate all the issues which got me off track. Has a no-nonsense, 'get right to it' approach. First time someone did the talk therapy as well - takes the time to really work with me - others saw me briefly and wrote a prescription, that was it. If you're going through the motions, don't bother. if you are finally ready to change see this doc asap.
