Therapists come in many shapes and sizes. First look at their credentials and educate yourself on what they mean. Most therapists in California will be an MFT (masters level education) or a PsyD (doctorate level education). Are they licensed? Do they treat the issues that you are dealing with?
Most importantly, are they someone you feel comfortable with? It is important to schedule a session, ask lots of questions, and be honest about how you are feeling. Then, make a decision about if this therapist is the one for you.
