About our Firm

Georgia’s Compassionate Family Law Firm

Fierer & Buerlein

Our Practice

Fierer & Buerlein, LLC’s founding partners, Gillian Fierer & Austin Buerlein have 30 years combined experience. Our attorneys started their legal careers at larger firms, but appreciate the boutique firm feel and the individual attention they can provide their clients at FB.

Committed, Compassionate Lawyers

We understand that domestic relations cases are saturated with anxiety and emotion. Although divorce and custody cases involve legal processes, they are often edged in human conflict and feelings of rejection, resentment, and loss. Transitioning through these legal corridors calls for the kind of competent and compassionate counsel that the attorneys at FB provide.

Our Attorneys represent clients in all kinds of domestic relations actions and have successfully represented thousands of clients throughout Georgia. We practice in the metropolitan Atlanta and in surrounding counties and are skilled at handling all divorce and child custody cases, including high asset divorces and complex custody modifications.

Our experienced legal team is also skilled and trained as mediators, arbitrators, and guardians ad litem.
