Temporary Closure


Due to COVID-19, we have made the difficult decision to temporarily close the office until further notice. The health and safety of our patients, employees, and community is of utmost importance to us and we believe that this is an important step in helping to reduce close contact points and promote social distancing.


If you experience an ocular emergency during this closure, please contact us at [email protected]. We are checking e-mail on a regular basis (phone messages are checked less frequently) and will try to respond to you in a timely manner.


Thank you for your understanding and we apologize for any inconvenience. Wishing you and your families continued safety and good health.
