Dear Dr Offenberger,

I just wanted you to know I had brought in a neighbors family member to your clinic a few weeks ago and was so very impressed with how well organized and professional your staff were in showing such care and kindness to patients. It really did impress me and others too, as it's rather a rarity to see how the patients were not rushed in and out but taken good care of.

It all adds to feeling confident, safe and so cared for by your unique staff. I must admit the patients also raved about you, which is also an added bonus to know how one has such confidence in their doctor.

I do hope such good caring staff prevails and how well they conduct themselves only makes more people turn to you. You are all super nice and deserve the good credit, this was the office on Balboa in Granada Hills.

Thank you all. With kindest regards,

H. Maynard


I want to take a second to give your entire staff praise for its tremendous service and hospitality, especially Dominic. I cannot say enough of how amazing she has been to Kamila on the times that she did her injections and not just being gentle but so very calming.

Kamila was so scared of needles and being around Dominic made her loosen up and she always looked forward to having her.

Warm Regards,

Lina C
