I have certainly worked with T's willing (and maybe more eager than myself) to set specific goals with specific treatment plans. I would suggest finding a more goal-oriented therapist if that is what you are looking for. Generally, T's that work for community clinics are more goal-oriented out of necessity (their funding sources requireit). More behaviorally-oriented T's, or ones specializing in shorter-term therapy would also be ones to look at.
I'm actually somewhat the opposite. While I have set goals I want to accomplish (ex: processing my trauma to lessen flashbacks and other unwanted PTSD symptoms), I also generally am looking for support from my T around every-day stressors.
I think some T's fall into "go with the flow" for every client because it tends to be easier - you support the client with whatever they come to you that day. While it can be great for some, it can be pointless for others.
Keep looking if you still want help with whatever you sought therapy for, and ask in the first session how they can help you. Let them know you are looking for concrete, measurable progress with a set treatment plan.
