About Us

Biller, Sachs, & Robert, a partnership of LLCs, is dedicated to providing our clients with professional, reliable, and cost-efficient representation. Our clientele encompasses a wide range of individuals and professionals, including many business organizations as well as municipalities. Biller, Sachs, & Robert is a partnership that includes Attorney Jon Biller, Attorney Brianna Kastukevich Robert, and Attorney Jeffrey Sachs.


Attorney Jon Biller has been litigating insurance coverage matters on behalf of policyholders for over 35 years and has recovered millions of dollars on behalf of his clients. Attorney Biller has also been a licensed Public Insurance Adjuster for over 40 years and continues to assist his clients in the resolution of their property damage claims.


Attorney Jeffrey Sachs is a third-generation legal advisor with over three decades of experience in transactional law.


Attorney Brianna Kastukevich Robert has been with the firm for almost a decade and her primary focus is insurance coverage litigation on behalf of policyholders and the representation of victims of serious personal injuries.


We are located in Hamden, Connecticut. Our attorneys are admitted to practice law in the States of Connecticut, New York, and Georgia; as well as the United States District Court. 


In an ongoing effort to better serve our clients, we are continually upgrading all of our resources. Members of our firm are active in many professional associations and civic organizations and frequently serve as guest speakers in their respective practice areas. Our attorneys utilize a team approach toward case resolution, collaborating with each other, our law clerks, and legal staff for assistance. In order to best represent our clients' interests, we also employ the services of accountants, engineers, adjusters, and other consultants, as needed.


It is our practice to assign an attorney, usually a partner, to each matter brought into our firm. That attorney has an ongoing responsibility for that matter until its ultimate resolution. It is also our practice to ensure that the responsible attorney maintains continual contact with our client.


When possible, we attempt to avoid litigation to resolve our clients' concerns so that we may provide them with the timeliest and most cost-effective representation. However, our firm takes great pride in our trial record and willingness to stand behind our clients and to litigate to the fullest extent of the law. We have a successful trial record and have argued several appeals before the Connecticut Appellate and Supreme Courts.


We pride ourselves in the representation of our clients, our ability to effectively communicate with them, keep their primary goals in mind, and provide them ongoing assistance with all of their legal and professional matters.
