I've been practicing for 50 years, and, other than word of mouth, which is not without imperfection, I do not know of any completely reliable way you find the details you are seeking.
Start by speaking with friends and family. Get word of moth referrals. Go online and see what others say about the lawyer. Look at various ratings but take those ratings with a grain of salt. Unhappy clients are more verbal than those who were very pleased, and often the client's dissatisfaction is more a result of the outcome than the lawyer's poor performance. Make appointments to consult with attorneys who practice in the area of law you need. The best way to choose a lawyer is a combination of work of mouth and your own gut feeling. Face to face conversation is always the best indicator. The lawyer who is a perfect fit for your friend or neighbor might not be for you. We lawyers are all different. The first rule of the relationship is that both the lawyer and the potential client must be comfortable with each other. Never rely merely on statistics.
The best way to find an attorney is to find someone who'll return your calls, that has some experience in the issues of your case, and that you interact well with. It's really no different than the process for picking a babysitter -- you interview a few and see who you are willing to trust with your children.
This answer is intended as informational only, and does not constitute legal advice or form an attorney-client relationship between us.
Try reviewing a specific area of law on the "super lawyers" website in your state. To be a "super lawyer", among other things, you have to obtain recommended legal elite status from your peers. That would be the first place I search.
