Explore Our Surgical Procedures
Conditions We Treat
Cranial & Cerebrovascular
- Aneurysms: Structural weaknesses in cerebral arteries requiring precise evaluation.
- Arteriovenous Malformations (AVMs): Complex tangles of abnormal blood vessels in the brain.
- Chiari Malformations: Structural defects in the base of the skull affecting brain tissue.
Tumor & Skull Base
- Gliomas & Glioblastomas: Primary brain tumors demanding immediate, aggressive strategic intervention.
- Meningiomas: Typically benign but critically located tumors arising from the protective membranes.
- Colloid & Pineal Cysts/Tumors: Deep-seated masses affecting fluid pathways.
Spine & Spinal Cord
- Degenerative Spine Conditions: Comprehensive management for chronic structural changes.
- Herniated Discs & Stenosis: Alleviating debilitating nerve compression and spinal narrowing.
- Spondylolisthesis & Complex Spine: Correcting instability and spinal alignment.
- Spine & Spinal Cord Tumors: Delicate removal of primary and metastatic lesions.
Advanced & Appropriate Procedures
Endovascular Treatments
Minimally invasive, catheter-based interventions to treat complex vascular lesions from within the blood vessels.
Endoscopic Procedures
Utilizing high-definition scopes for specialized, minimally disruptive pathways, including transsphenoidal approaches for pituitary tumors and endoscopic third ventriculostomy.
Tumor & Radiosurgery
Highly targeted, precise surgical resection paired with stereotactic options to address skull base and deep-brain lesions.
Keyhole & Minimally Invasive Surgery
Ultra-precise cranial approaches leveraging natural corridors- such as the eyelid or eyebrow- to minimize recovery time and cosmetic disruption.
Spine Procedure & Reconstruction
Tailored surgical stabilization utilizing advanced spine instrumentation and fusion techniques to restore structural durability and biomechanical integrity.

Meet Dr. Michaela Lee
Fellowship-Trained Spine and Cerebrovascular Neurosurgeon Dedicated to Precision, Partnership, and Patient-Centered Care.
Dr. Michaela Lee is a board-certified neurosurgeon specializing in complex spine, cerebrovascular, and skull base surgery. She completed her neurosurgical residency at The George Washington University Medical Center in Washington, D.C., where she also pursued an enfolded fellowship in complex spine surgery.
To further her expertise, Dr. Lee completed a prestigious Cerebrovascular and Skull Base Fellowship at the Barrow Neurological Institute under the direct mentorship of Dr. Peter Nakaji- one of the most widely respected authorities in neurosurgery. She also heavily utilizes minimally invasive and endoscopic techniques that explicitly support faster, smoother recovery timelines for her patients.
Dr. Lee founded Helios Neurosurgery on a clear principle: Be a good human while treating them. Her clinical philosophy trades performative drama for clear, quiet command, ensuring every patient and referring physician experiences unparalleled technical capability delivered with genuine respect and approachability.
