Sisu Clinic Has Landed on the Upper West Side

There is a particular kind of patient who lives on the Upper West Side.

They have read three different studies on retinoids before stepping into a single clinic. They cross-check their injector’s license, review their training, and want to know who founded the practice. They have heard about people getting overfilled in midtown and are not interested. They want a clinic that treats them like an adult, gives them science, and respects their face.

That patient now has a clinic two blocks away.

Welcome to Sisu Upper West Side

As of October 2026, Sisu Clinic is officially open on the Upper West Side. Our newest Manhattan location joins our existing NYC clinics in the Upper East Side, Flatiron and SoHo, and our wider global network across Ireland, the UK and Houston.

This makes UWS the fourth Sisu clinic in New York, and the first to sit west of Central Park.

If you’ve been waiting for a doctor-led medical aesthetics clinic on your side of the park: it’s here.

Why the Upper West Side?

The honest answer is: our patients told us to.

Across our other Manhattan clinics, we noticed a pattern. A meaningful chunk of our regulars were crossing the park or coming up from midtown for treatment, every three months, often after work, often in the rain. They asked, repeatedly, when we were opening on their side.

The Upper West Side is one of the most patient-led neighbourhoods in the city. Highly educated, deeply local, family-anchored, and known for being slow to trust but loyal once you’ve earned it. People here don’t change clinics on a whim. They want their dentist, their dermatologist, their pediatrician, their pharmacist all within a ten-block radius, and they want to know each one personally.

That fits Sisu’s model exactly.

What you can book at Sisu UWS

The full Sisu menu is available at our Upper West Side clinic, including:

• Botox and Dysport for forehead lines, frown lines, crow’s feet, lip flips, masseter (jaw slimming), gummy smile, chin smoothing and underarm sweating.
• Hyaluronic acid dermal filler for lips, cheeks, chin, jawline and under eyes.
• Rejuran Microneedling aka The TikTok Viral Salmon sperm treatment for hydration and skin quality.
• Sculptra for collagen stimulation.

What stays the same

Everything that defines Sisu transfers to UWS without compromise:

• Doctor-founded, doctor-led — Sisu was founded by Dr Brian Cotter and Dr James Cotter and operates under medical oversight worldwide.
• Licensed medical professionals only — every injector is a nurse practitioner with advanced aesthetics training.
• Free consultations — every new patient gets a complimentary, no-pressure consultation.
• Conservative house style — natural results are the brief, every time.
• Two-week follow-up included for new patients — we adjust at no charge if needed.
• Shared records across all four NYC clinics — switch between locations whenever your week demands it.

What’s different about UWS

A few things were designed specifically for the neighbourhood.

After-school and post-work appointments

UWS schedules around school pickup, parent commitments and Lincoln Center performances. Our late-afternoon and evening slots reflect that. Saturday slots are available.

Weekday-morning availability for the work-from-home crowd

If you work from home and want a 9.30am Botox appointment that’s done before your first call, those slots exist.

Direct subway access from the East Side

Easy crosstown bus and short subway rides mean existing UES Sisu patients can move their appointments to UWS without losing their injector continuity, since records are shared between locations.

How to book

Three options:

Online — sisuclinic.com/ Online booking is open 24/7.

Phone — call the clinic on 646 693 0132

In person — walk in to ask a question or book an appointment.

Every new patient appointment includes a complimentary consultation. You will not be pressured to treat on the day. If we don’t think a treatment is right for you, we’ll say so.

A note from our doctors

Sisu was founded on a simple principle: patients deserve medical-grade aesthetics from medical professionals, in a setting that takes their face as seriously as they do.

Opening on the Upper West Side is not just a new address. It’s a commitment to a particular kind of New Yorker — one who reads, asks questions, and won’t be sold to. We’re looking forward to meeting you.
