Welcome to Lawrenceville Internal Medicine

We are a decidedly different kind of primary care practice. From our inception we have been committed to offering patients an opportunity to be heard and involved with their care. We pride ourselves on taking the extra time needed to truly understand our patients and their concerns. We believe in the sanctity of the doctor-patient relationship and hope to restore your belief that high quality medical care is founded in this important relationship. We have united the traditional ideals of practicing medicine to the future of medicine. We were among the first practices to adopt an electronic health record to track your medical history. We utilize an integrated and secure patient portal to enhance communication with our patients. Most importantly, we practice evidence-driven medicine. That is, we base medical decisions on the most current medical literature.

We believe that the marriage between “old-fashioned” values and modern medical decision-making defines who we are as practitioners. We sincerely hope you give us an opportunity to provide your primary care.

As a valued patient of Endocrinology Associates of Princeton, LLC and Lawrenceville Internal Medicine Assoc, LLC (collectively, the “Practice”), we are writing to make you aware of a data security incident involving your email address that came to our attention on October 31, 2019. Although we have no reason to believe that your email address or any other personal information has been accessed or misused in any way, we are writing to make you aware of the incident so that you may take any necessary precautions.

To communicate certain administrative changes concerning the Practice and its operations, the Practice sent a standardized announcement email to patients on October 29, 2019.

The Practice takes the protection of your personal and medical information very seriously. We regularly review our systems and privacy and security practices to enhance those protections. In response to this incident, the Practice has taken steps to prevent the recurrence of similar incidents. The Practice provided supplemental privacy and security training for IT staff, utilizes a different system to circulate email communications to patients and also strengthened security policies and procedures relating to email communications.
We sincerely regret any inconvenience or concern caused by this incident. Although we are not aware that your email address or personal information has been compromised and the risk of potential exposure is low, we want to make you aware of resources you may access to help safeguard your personal information.
