Our commitment is to our patients.
In our practice, our focus is you—the patient. We respect and value the relationships we have with our patients. Our goal is to provide you with personalized medical care and meaningful access to your physician. Office visits are scheduled to allow enough time to address your needs and concerns, and telephone calls are returned promptly. We take our responsibility for your well being seriously—our responsibility does not end when our office closes. We are available during regular office hours and can be contacted directly after hours for urgent medical issues.
We believe that caring for you before, during, and after an illness leads to a better understanding of your health, better care, and better outcomes. We see patients in our office, at Highland Park Hospital and Northwestern Lake Forest Hospital, and at many local rehab facilities when needed. We are independent physicians, which allows us to refer patients to the best specialists, regardless of network affiliation. We take the time to coordinate care among our patients’ specialists and help our patients navigate the complex healthcare environment.
