Deciding to do therapy is an important step in the process of meeting with a therapist, but a couple steps remain after doing so. Most importantly, one has to figure out a therapist to work with. But, finding a good therapist is a bit trickier than finding other service providers. You can't hop on Facebook and ask for recommendations for a good therapist, but doing so for a plumber or HVAC person would be perfectly acceptable. Another reason is the lack of good information about therapists. Services like Yelp or Angie's List provide us with all sorts of reviews on different businesses, but similar information is uncommon for therapists.
If a person was looking for a therapist and didn't know where to start, a web search likely would be the first step, and the first results would be from PsychologyToday.com and GoodTherapy.org. Different profiles would come up, and you could read about the different therapists including their credentials, their approach, and what types of insurance they accept. A phone call would be a perfectly acceptable next step to get a sense of who they and whether it would be a good fit. The Psychology Today article linked to below comprehensively lists some good questions, but here are some of them:
