Thyroid Surgeon in Tarzana
Tarzana knows good medicine; its own hospital corridor sees to that. But thyroid and parathyroid surgery rewards concentration above convenience, and Dr. Jason S. Cohen, MD, FACS practices it exclusively, thirty five to forty five minutes over the hill at the Cedars-Sinai Medical Towers.
The Case for Crossing the Hill
Plenty of Tarzana care rightly stays local. The neck is the exception worth a second thought: reading thyroid ultrasounds, sizing operations, and protecting the laryngeal nerves are skills sharpened by repetition, and repetition lives in a practice that does nothing else.
From the streets south of Ventura Boulevard and the flats off Reseda, the 101 east to the 405 south, then Sunset east to San Vicente and 3rd Street, runs thirty five to forty five minutes off peak. Telehealth carries the consultation and the aftermath, so the hill features only twice or three times.
Dr. Cohen reviews your originals himself, examines you once, and hands you a decision with its reasoning: surveillance with dates, focused testing, or a precisely sized operation.
What One Surgeon Covers
Tarzana patients use the practice across its six service lines.
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 Makes the Crossing From the 91356
The pattern: nodules parked under casual observation, calcium elevated across years of panels, goiters grown patient with their owners, and biopsies that need an oncologic surgeon’s judgment before anyone schedules an operation.
Second opinions on valley recommendations are common and welcomed here; one review of the imaging and pathology either confirms your plan or improves it, and both outcomes justify the trip.
Surgery already proposed locally? One crossing for a second read is cheap insurance on your neck. Call 310-986-3359.
Measured Twice, Cut Once
The practice bias is conservative: lobectomy over total thyroidectomy where oncologically sound, focused parathyroid removal over exploration, and surveillance instead of surgery when the evidence permits.
In the operating room, nerve monitoring runs continuously, hormone levels confirm parathyroid cures before closing, and incisions stay short inside natural creases.
Two Crossings, Maybe Three
Consult Without Driving
Imaging and labs go ahead; the telehealth consultation reaches conclusions the same afternoon.
One Consolidated Visit
Examination and any remaining tests stack into a single trip over the hill.
Operate and Return
Surgery at Cedars-Sinai, one night or less for most, one in person check near a week, then video from Tarzana.

Frequently Asked Questions
How long is the drive from Tarzana?
Thirty five to forty five minutes off peak: the 101 east to the 405 south, then Sunset east to San Vicente and 3rd Street. Telehealth keeps total crossings to two or three for most patients.
Tarzana has hospitals. Why go over the hill for this?
Because thyroid and parathyroid outcomes track with surgeon volume in these specific operations. For most care, staying local is right; for this, concentration in a dedicated practice earns the trip.
Can I get a second opinion on a surgery already scheduled?
Yes, and it is a routine reason Tarzana patients come. Bring the imaging, pathology, and the proposed plan; Dr. Cohen will confirm it or explain exactly where he differs and why.
How does the telehealth part work in practice?
You send records, meet by video, and leave with a plan. Results conversations and long term follow up run the same way, keeping in person time to the examination, surgery, and first check.
What operations beyond the thyroid does Dr. Cohen perform?
Parathyroid surgery, thyroid cancer operations with neck dissection when needed, breast cancer surgery, robotic procedures, and advanced laparoscopic general surgery.
Where would I have surgery, and for how long?
At Cedars-Sinai, adjacent to the office. Most thyroid and parathyroid patients stay one night or less before the drive home.
