I had a VBAC in '09 and discovered that the physician's and his/her partners' birth philosophies can influence your personal VBAC success.
It's important to ask why, what and is this necessary throughout your pregnancy in order to obtain a more positive outcome. The outcome may not be as you expect, but you'll have a greater sense of well being, knowing you were present during decision making. Dr. Snider seems open to VBAC's, as does his practice.
I have only heard positive comments regarding his bedside manner as well.
