If you are planning to send corrspondence to me through the U.S. Postal Service, it will take about three weeks for your letter to be delivered due to screening procedures. Other packages may take even longer. I ask that you be patient with written correspondence to and from my office, and when possible use alternatives such as email , phone, or fax. Thanks.
