Dr Schreier is an excellent doctor. He is knowledgeable, conscientious and caring. He is the best doctor in town. He is attentive and pays attention to what his patients needs are. I am so glad that he is my doctor.

Dr Schreier and his staff are warm, friendly and very caring. I needed to have my gall bladder removed and was referred his office. My surgery went so well and I had very little discomfort after surgery. I would definitely recommend him. Excellent, caring surgeon!
in Tarzana, Ca |
Dr. Schreier is the best ! Just one visit, and operation went very well. One week after the operation i am not only recovered from the operation but feel like a new person - no more infected gallbladder! Dr. Schreier is kind, trustworthy, knowledgeable, concise, obviously an excellent surgent ! Thank you Dr. Schreier!
Chatsworth, CA |
The only issue I had, but this is the case with any doctor, is that most of the time the hospital costs are separate, so you have to be sure you understand the doctor's fees and the hospital's fees (if hospitalization is required) and talk to your insurance. I got a big surprise from the hospital! Not in a good way.
in Thousand Oaks, CA |
I saw Dr Schreier in the new Thousand Oaks office. He removed a skin melanoma from a visible place on my chest. He did a fabulous job and got all of it out. My incision is almost unnoticable. I highly recommend this Surgeon!!
in woodland hills, ca |
how many ways can you say excellent? I had a situation requiring surgery. Dr. Schreier was outstanding in every aspect. Appointments, explanations, recommendations, follow ups, etc. I can't recommend a better surgeon, who listens and has empathy coupled with a sense of humour and a smile. So imporant.
in Agoura Hills, CA |
Dr. Schreier took my complaint very seriously, even though tests the hospital and my GP performed proved to be somewhat inconclusive. He went out of his way to rule out any other diagnoses before removing my gall bladder. His staff is very courteous and the surgery scheduler, Kerilyn Hurley went above and beyond the call to work with me on scheduling a good surgery date within a limited amount of time. I would highly recommend to anyone seeking a great surgeon with amazing bedside manner.
