I found Dr. Dorothy Buckner https://my.cigna.com/web/secure/consumer/directory/doctors/2702833?latitude=37.3394444&longitude=-121.8938889&city=where-I-live&stateCode=CA&zipCode=&formattedAddress=where-I-live%2095108&locationId=220191025221023317828122932251 but I could not find a Dr. Jennifer Barron. Are you sure that this is the right name and spelling?
