There are many great and reliable family and marriage therapists in just about every larger community. The best way to find one is to ask for a solid recommendation from friends or family members that you trust who have gone to see one in your area. Other ways to find one are to look online at sites such as psychcentral.com or goodtherapy.org and search for one near you. You can also look up therapists on sites of various psychological associations such as the American Counseling Association, American Psychological Association, or Counseling Psychology on the American Board of Professional Psychology site.
I would ask friends and family for references. Alternatively, your church, community centre or doctor could also give you the names of some they are familiar with. You could look online if you want more privacy, but you never know how reliable the websites are. But of course if you findthe therapist doesnt help you, you dont have to keep returning either.
It really depends on your goals--I work in tandem with many MFT's because sometimes there are urgent issues that need fixed immediately and that is what I specialize in, and other times there are underlying severe issues that require more involvement with other professionals. I am a Strategic Interventionist and I help couples that are on the verge of divorce or separation who are dealing with issues such as infidelity, death of a child, trust issues, anger and abuse issues, and a plethora of other issues. The best way to choose what modality will work best for you is simply by having a conversation. I would be more than happy to talk with you about what your issues are, whether I can help or not, and if I can't or don't feel we are a good match, I have a number of MFT's and other professionals that I can refer you to that will be able to help! :D I wish for you a life filled with Gratitude, Abundance, and Passion!
