Thyroid Surgeon in Hermosa Beach
Hermosa keeps life simple: the Strand, the pier, and as few reasons to sit on a freeway as possible. When the reason is a thyroid or parathyroid finding, it is worth making the trip count. Dr. Jason S. Cohen, MD, FACS, a board certified surgical oncologist who operates on these glands exclusively, structures care so Hermosa patients drive north only when it matters.
Small Town Simplicity, Big City Surgery
A finding in the neck tends to surface casually here: a lifeguard physical, a scan after a surfing shoulder, a wellness panel with calcium a notch high. The town’s instinct is to keep things low key, and the right specialist visit preserves exactly that: one thorough evaluation instead of a season of scattered appointments.
From the Sand Section, the hill, and east of Valley Drive, the 405 north to the 10 east and off at La Cienega runs forty to fifty minutes to the Cedars-Sinai Medical Towers. Telehealth does the rest of the work from a barstool at home.
Dr. Cohen reviews the imaging himself, examines you once, and speaks plainly: most nodules watch, some operate, and either way you leave with the reasoning, not just the verdict.
Six Services, One Surgeon
Hermosa Beach patients use the full practice, not just the thyroid clinic.
Thyroid & Parathyroid Surgery
Thyroidectomy, lobectomy, and focused parathyroid operations with nerve monitoring throughout.
Minimally Invasive Surgery
Small, carefully placed incisions and faster recoveries wherever the diagnosis allows.
Surgical Oncology
Fellowship trained cancer surgery, from thyroid malignancies to complex tumors.
Robotic Surgery
Da Vinci robotic technique for precision in confined anatomy, adopted early by Dr. Cohen.
Breast Cancer Surgery
Oncologic breast surgery from the former director of the Cedars-Sinai surgical oncology and breast clinic.
General Surgery
Advanced laparoscopic general surgery, handled with the same specialist standards.
What Rides Up From the 90254
The usual suspects: nodules flagged on incidental imaging, early thyroid cancers in people who found them by paying attention, goiters that started photobombing, and parathyroid disease unmasked by a kidney stone or a DEXA scan.
None of these needs panic; all of them need one competent look. The consultation exists to sort the watchers from the operations, and the majority land in the first pile.

The Least Surgery That Fully Works
The bias here is conservative: monitor when monitoring is safe, remove half the gland when half suffices, and reserve total thyroidectomy for the cases that genuinely require it. Smaller operations mean faster paddling.
Every case runs with nerve monitoring and magnification; parathyroid operations confirm the cure with hormone levels before closing; incisions hide in natural creases.
Three Steps, One Freeway Day
Video First
Imaging and labs go ahead; the consultation happens by telehealth and reaches real conclusions.
One Trip North
The examination and any remaining workup stack into a single visit to the Medical Towers.
Surgery and Back to the Strand
The operation at Cedars-Sinai, typically one night or less, one check about a week later, then video from home.

Frequently Asked Questions
How far is the office from Hermosa Beach?
Forty to fifty minutes north: the 405 to the 10 east, off at La Cienega and up to 3rd Street. The telehealth first structure keeps most patients to two or three total trips.
When can I surf again after thyroid or parathyroid surgery?
Ocean immersion waits for the incision to fully seal, usually about two weeks, while walking and light land training return within the first week. Your timeline comes in writing before the operation.
A DEXA scan showed bone loss and my calcium runs high. Connected?
Often, yes. An overactive parathyroid gland strips calcium from bone, and declining density in an otherwise fit adult is a classic presentation. Confirming it takes bloodwork and imaging; a focused operation cures most cases.
Do I really need a subspecialist for a small nodule?
You need one correct read more than you need proximity. Most small nodules earn surveillance, but the features that matter are subtle on ultrasound, and a surgeon who reads them daily calibrates the plan properly the first time.
What else does Dr. Cohen operate on?
Parathyroid disease, thyroid cancers with neck dissection when needed, breast cancer, robotic procedures, and advanced laparoscopic general surgery. He is a fellowship trained surgical oncologist.
Where does surgery happen?
At Cedars-Sinai, next to the consultation office. Most patients stay one night or less before the drive back down the 405.
