Thyroid Surgeon in Santa Monica
Living by the coast should not mean settling for the nearest surgeon when your thyroid needs attention. Dr. Jason S. Cohen, MD, FACS is a board certified surgical oncologist devoted to thyroid and parathyroid operations, and his Cedars-Sinai Medical Towers office is a straight run up the 10 or along Wilshire from anywhere in Santa Monica.
Specialist Thyroid Care for the Westside
Santa Monica has excellent primary care and imaging, which is usually where a thyroid problem first shows itself: a nodule spotted on a scan ordered for something else, or calcium running high on an annual panel. What comes next is the decision that matters, and it deserves a surgeon who does this work every week.
Patients come to Dr. Cohen from Ocean Park and Sunset Park, from the condo towers along Ocean Avenue, and from North of Montana. The drive east on the 10 to the Robertson exit, or along Wilshire through Westwood and Beverly Hills, lands at the Cedars-Sinai campus in twenty five to thirty five minutes most of the day.
The visit itself is unhurried. Dr. Cohen reviews your ultrasound and bloodwork personally, examines your neck, and gives you a plain recommendation. When monitoring is the wiser course, he says so, and telehealth handles much of the follow up so the 10 does not become part of your routine.
One Practice, Six Surgical Services
Santa Monica patients see Dr. Cohen for far more than thyroid disease.
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 Brings Westside Patients In
The steadiest stream of referrals involves thyroid nodules that need a surgical opinion, thyroid cancers confirmed on biopsy, goiters that have begun to press on the airway, and parathyroid disease behind stubbornly elevated calcium.
Active people tend to ask the same two questions: how soon can I get back in the water or on the trail, and what will the scar look like. Both have encouraging answers, and both are discussed candidly before anything is scheduled.
Told you need a thyroidectomy? A second opinion from a fellowship trained surgical oncologist is a short appointment that occasionally changes the plan entirely. Call 310-986-3359.
Small Incisions, Monitored Nerves
The structures at stake in neck surgery are unforgiving: the nerves that drive your voice, the glands that control calcium. Dr. Cohen uses intraoperative nerve monitoring in every case and magnification throughout, and he was an early adopter of robotic thyroidectomy.
Incisions are planned to sit inside a natural crease of the neck, kept as short as the operation safely allows. For suitable cases, hidden incision approaches avoid a visible neck scar altogether.
From First Call to Full Recovery
Records First, Then a Real Conversation
Book by phone or online and send your imaging ahead. Dr. Cohen reviews it personally, in person at the Medical Towers or by video, and tells you whether surgery is warranted at all.
An Operation Matched to the Diagnosis
From lobectomy to total thyroidectomy with lymph node dissection, the plan fits the disease, never more than you need.
Home to Santa Monica Quickly
Surgery takes place at Cedars-Sinai, next to the office. Most patients spend a night or less in hospital and are back at the beach pace of life within days, with strenuous exercise resuming on a clear timeline.
Getting Here From Santa Monica
From most of Santa Monica the fastest route is the 10 east to the Robertson Boulevard exit, then north to 3rd Street. From North of Montana or the Wilshire corridor, Wilshire east through Westwood and Beverly Hills, then San Vicente up to 3rd, is the surface alternative. Plan on twenty five to thirty five minutes from the 90401 through 90405 ZIP codes outside rush hour.
Valet and structure parking serve the Medical Towers, and the 8635 W. 3rd Street entrance is the West Tower. Suite 880W is on the eighth floor.

Frequently Asked Questions
How long is the drive from Santa Monica to Dr. Cohen’s office?
Usually twenty five to thirty five minutes. The 10 east to Robertson is quickest from Ocean Park and Sunset Park, while Wilshire east works well from North of Montana. The office is in the Cedars-Sinai Medical Towers at 8635 W. 3rd Street.
Can the consultation happen by video so I skip the drive?
Yes. Initial consultations, second opinions, and most follow up can be handled by telehealth. In person visits are reserved for the physical examination, surgery itself, and the early post operative check.
When can I get back to running, swimming, or the gym?
Light activity typically resumes within a week of thyroid or parathyroid surgery, with strenuous exercise around the ten day mark depending on the operation. Dr. Cohen gives you a specific timeline rather than a vague one.
A nodule showed up on my ultrasound. Does it need to come out?
Most nodules do not. Surgery becomes the right answer when biopsy results suggest or cannot exclude cancer, when a nodule compresses the airway or swallowing, when it produces excess hormone, or when it grows steadily. Otherwise monitoring is a legitimate plan.
Does Dr. Cohen treat anything besides the thyroid?
Yes. He is a fellowship trained surgical oncologist and board certified general surgeon. Santa Monica patients also see him for parathyroid disease, breast cancer surgery, robotic procedures, and complex general surgery.
Where would my operation actually happen?
At Cedars-Sinai, immediately adjacent to the consultation office. Most thyroid and parathyroid patients stay one night or less before heading home to Santa Monica.
