I just turned 30 and believe I am a between 5/6 on norwood scale. My pops went and saw Dr. Ziering and put down a non-refundable payment for both of us for the middle of September. My pops never considered seeing another doctor. I have been searching the web and have read some negative reviews of Dr. Ziering from Newport Beach. I told my pops and set him up with Dr. Siporin next week. I have heard many good things about Dr. Siporin. If all goes well with Dr. Siporin we will go with him and lose the $1000 non-refundable payment because this is a huge decision. We are choosing doctors in Los Angeles/OC area only. Any comments on Ziering or Siporin? Thanks.
