Autonomic Dysfunction

• SIGNATURE

Autonomic Clinic

We use dedicated autonomic nervous system tests (HRV, tilt-table, Valsalva maneuver) to identify hidden causes, while our neurosurgery and neurology specialists simultaneously correct structural and functional imbalances.

Brain & Nerve Clinic

Our neurosurgery and neurology specialists assess migraines, tension and cluster headaches, dizziness, and brain fog together, then plan care around each patient’s symptoms.

Pain & Regenerative Clinic

We address the root causes of chronic pain through regenerative injection therapies including prolotherapy, PRP, and PDRN, promoting self-healing of damaged ligaments, tendons, and cartilage tissue under ultrasound guidance.
