Thyroid Surgeon in Marina Peninsula
Life on the Peninsula runs between the main channel and the sand, and it rewards keeping obligations off the strand. When the obligation is a thyroid or parathyroid finding, Dr. Jason S. Cohen, MD, FACS, a board certified surgical oncologist devoted to these operations, keeps it to a handful of trips from the Cedars-Sinai Medical Towers.
Walk Street Living, Corridor Grade Surgery
The Peninsula’s walk streets breed a particular efficiency: everything you need within a bike ride, and everything else planned carefully. A neck finding belongs in the second category, planned once, evaluated properly, and resolved without becoming a recurring calendar item.
Via Marina to Washington Boulevard, east to La Cienega, and north to 3rd Street reaches the Cedars-Sinai campus in about thirty minutes from the 90292 walk streets. The consultation itself happens by video first, so the drive waits for the examination.
Dr. Cohen reads your imaging personally, examines you once, and gives a recommendation built to hold: surveillance with real dates, targeted testing, or an operation sized exactly to the finding.
Six Services, One Standard
Peninsula residents use the full breadth of Dr. Cohen’s practice.
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 Comes Off the Peninsula
The caseload mirrors the lifestyle: nodules found on thorough wellness imaging, early thyroid cancers in people who monitor themselves closely, parathyroid disease surfacing as kidney stones or fatigue on the water, and goiters that paddleboarding posture stopped hiding.
Early findings deserve proportionate responses. The consultation exists to sort watchers from operations, and to say so plainly either way.
Paddling feels harder and calcium runs high? Fatigue with elevated calcium has a fixable cause more often than people expect. Call 310-986-3359.
Small Surgery, Fast Water Return
Operations stay as small as the disease allows: lobectomy where sound, focused parathyroid removal with intraoperative hormone confirmation, incisions short and creased.
Nerve monitoring runs continuously in every case, and recovery plans are written for the Peninsula: when the bike path returns, when the water does.

Frequently Asked Questions
How long is the drive from the Marina Peninsula?
About thirty minutes: Via Marina to Washington, east to La Cienega, and north to 3rd Street, arriving at the Cedars-Sinai Medical Towers with valet at the West Tower.
How many in person visits does a typical case need?
Two or three: the examination day, surgery, and a check about a week later. Consultation and later follow up run by telehealth from home.
When can I swim, paddle, and ride again after surgery?
The bike path within days for most patients, strenuous paddling around ten days, and water immersion once the incision fully seals near two weeks. Dates come specific to your case.
Does a nodule that has never changed still need a look?
One proper look, yes. Stability is meaningful, but the ultrasound features decide the surveillance interval, and confirming those once with a specialist puts the question away cleanly.
What else does Dr. Cohen operate on?
Parathyroid disease, thyroid cancers including neck dissection, breast cancer, robotic procedures, and advanced laparoscopic general surgery. He is a fellowship trained surgical oncologist.
Where is the surgery itself?
At Cedars-Sinai, adjacent to the office. Most thyroid and parathyroid patients are back on the Peninsula the next day.
