At Optimum Neurology, we want our patients to live their best, most complete lives.

Neurological conditions can be incredibly disabling. From physical symptoms like tremors or weakness to mental symptoms like mental status changes or exhaustion, patients come to Optimum with a wide range of complaints.

David S. Tabby, D.O., with the help of Michelle Roque, provides patients with the care they need to stabilize their disease or find a new, healthier treatment. We take pride in offering the most modern and up to date treatments as we approach each patient’s condition and symptoms with a whole-patient approach. Many neurological conditions can be triggered or worsened by lifestyle factors; we help our patients understand what daily living items can be adjusted to improve their functioning.

If you have been recently diagnosed with a neurological condition, are looking for a fresh take on your disease and its treatment, or have noticed new or worsening symptoms, contact David S. Tabby, D.O., at Optimum Neurology for a consultation.
