Intake Process
To simplify your experience in finding the right attorney, here is the intake process so you know what to expect when calling our office.

1
Our intake process helps us determine if we can handle your matter while managing the needs of our existing clients. Our case intake manager will ask you basic questions. Feinberg & Waller, APC, limits the number of cases we accept because we’ve found that selectivity advances our commitment to excellence.

During the intake process, we run a conflict check to ensure we have not previously spoken with the other party in your matter. If we determine that there is no conflict, our case intake manager will go over our option of hourly billing or a tailored fixed pricing structure and the price range should the potential client choose to retain us hourly. While some clients may prefer to be billed hourly, our fixed pricing model may better align with your matter by offering personalized pricing structures and client participation in pricing decisions. Our price caps provide financial certainty, empowering you to make informed decisions while shifting the risk away from unpredictable costs.
