Dear Patients,

I wanted to share with you that my husband, Dr. Jerold Yecies, passed away on March 12th. He practiced in Stockton for 47 years. Jerry felt very privileged to be your physician and he was deeply concerned for the welfare and health of each and every one of you. He was dedicated to staying at the forefront of emerging science and treatment for asthma and allergy. He saw a full day of patients the day before he passed away and that is exactly as he would have wanted it. It was his life’s work.

Dr. Yecies’ partners, Dr. George Bensch, Dr. Gregory Bensch, and Dr. Michael Balduzzi will be available to continue your care with the same dedication that he provided. They have full access to your medical records and will be able to provide the best continuity of care.

Wishing you good health,

Judith Yecies
