After years of seeing multiple specialists with little progress, we were fortunate to find Dr. Sullivan at Initia Nova. He is knowledgeable, compassionate, and truly listens. The SPG and other nerve blocks he provided have made a huge difference for my son’s headaches and migraines. Highly recommend! update; I really can’t say enough about Dr Sullivan and his team you will not find a practice anywhere that is more personal and caring about your well being. Dr Sullivan knows you personally you are not just a file he grabs when he walks in like most practices these days. He will listen and his experience w medicines and out of the box thinking for your personal pain both mentally and physically truly reflects his passion for his patients. We drive 1.5 hours each way just to see him because finding someone who cares that much is worth the drive.
