Dr.Blum is great ortho, However a very poor billing practice. Do your research before seeing him. Also be aware of hidden charges, don't leave use a credit card with him, he keeps it on file, and then they charge your credit card for the full balance. Most peoples claims are denied due to poor documentation by his office. Also BE AWARE ANAHEIM SURGICENTER, its in his same office its owned by him, and it is not contracted by ANY insurance company, most claims are denied leaving you with a hefty bill!!!!!
