CPAs and Legal Assistants

We utilize trained independent contractor professionals who are not attorneys; they work with our clients but do not give independent legal advice. Our office manager & legal assistant Dorenda K. Cisneros has been with the firm for over a quarter of a century. We also work closely with independent CPAs according to the needs of our clients; e.g., return preparation. We often recommend such professionals to our clients from among our nationwide network. It is our practice to hire such professionals under a “Kovel” agreement to protect the attorney-client privilege.
