Traumatic Brain Injury (TBI)

We are a team of board certified physicians who routinely evaluate cases of TBI, concussion, and whiplash injuries. After taking a thorough history coupled with a detailed physical examination and review of medical records including imaging, we can comment on causation of injuries as well as prognosis and reasonableness and necessity of treatment.

Dr. Shawn Zardouz has researched the effects of TMS (Transcranial magnetic stimulation) among veterans diagnosed with mild traumatic brain injury (mTBI). He has also studied the effects of onabotulinum toxin (botox) injections among patients with chronic migraine.

Chronic Pain

We specialize in all pain conditions ranging from neck/back pain, neuropathy, and complex regional pain syndrome (CRPS) to facial pain and TMJ (temporomandibular joint) dysfunction. By researching the complexity and mechanisms of chronic pain transmission as well as providing the latest treatments associated with these conditions on a daily basis, we are experts in our fields. We routinely evaluate a variety of cases ranging from slip and fall accidents to motor vehicle accidents and assaults.
