Is there a Dr. in Northern CA. that does Sculptra butt lifts?

I appreciate your question.Don't let the distance discourage from finding the right doctor for this procedure. We inject Sculptra on a regular basis in my office. We use it all
over the body and have been injecting Sculptra into the buttocks since
last summer. Sculptra to the buttocks is a newer procedure, but the
patients I've treated have had good results. 
Getting good results
is about selecting the best patients for this procedure. We start all
our patients with 8 vials and can do another 8 vials 6 to 8 weeks after
the initial injection. You can go all the way up to 20 vials and
get some significant enhancement.
This procedure is not meant to be a replacement for a Brazilian buttock lift with fat injections. It is a different kind of procedure and results. Sculptra is safe, is done in the office, and makes your body generate
volume by building up collagen. That means you can work out later and
you won't lose volume if you lose weight or if you had fat grafting. It
is a safe option compared to surgery. I don't think the distance from
here should discourage you from finding an expert injector.
Maintenance injections will be required by most patients. Watch my video link below to see how it's done!

Far more important than the technique is the skill and experience of your plastic surgeon. Choose your surgeon rather than the technique and let them explain why one technique may be better than another.  See the below link on some suggestions on finding the most qualified Plastic Surgeon for you.  Always insist on a board certified plastic surgeon.
