About

Allen Kamrava, MD

Board-certified colorectal surgeon. Built a dedicated HS program for the patients his specialty kept missing.

Board-Certified Colorectal Surgeon based in Beverly Hills. Teaching faculty at Cedars-Sinai. Director of a focused hidradenitis suppurativa program emphasizing follicle-directed laser therapy and CO₂ tunnel closure for perianal, perineal, gluteal, and inguinal disease.

Why HS

How a colorectal practice became an HS program.

After more than fifteen years treating perianal disease, the pattern became impossible to ignore. Patient after patient arrived with diagnoses of recurrent abscess, complex fistula, or pilonidal disease — and on examination, what they actually had was perianal hidradenitis suppurativa that had been missed for years.

Standard surgical approaches — repeated incision and drainage, fistulotomy, wide excision — were not just failing to resolve the disease. In many cases they were making it worse, scarring the anatomy and complicating the eventual definitive treatment.

The international HS literature was telling a different story. Follicle-directed laser therapy with prospective data behind it. Anatomic, follicle-respecting surgical techniques using CO₂ to follow the disease rather than block-excise it. Multidisciplinary protocols coordinating dermatology and surgery. The tools to do this work better existed; they were not part of the standard American surgical training that these patients were funneled into.

Building a dedicated HS program meant studying those protocols in depth, traveling to learn from the groups pioneering the work in Europe, integrating both laser modalities into the practice, and rebuilding the patient experience around what HS patients actually need: a real diagnosis, a multi-modality plan, an honest conversation about limits, and a clinician who has chosen to take this disease seriously.

HS patients deserve better than the system has been offering them. That is the entire reason for this program.

Colorectal training is the foundation that makes this work appropriate for perianal, perineal, and inguinal HS — anatomy that most dermatologists and aesthetic-medspa providers cannot comfortably address, and that plastic-surgery wide excision often over-treats.

Clinical philosophy

Four commitments that shape every visit.

Diagnosis before procedure
Many of the patients we see have been treated for years under the wrong label — recurrent abscess, pilonidal disease, fistula. The first job is to name the disease correctly. A procedure offered before the diagnosis is settled is the wrong procedure.
Multi-modality by default
HS is a disease of follicles and structural damage. A single tool addresses one half of that. The treatment plan combines follicle-directed therapy, anatomic surgery, and ongoing dermatologic management — not because it sounds thorough, but because it works better.
Honest about limits
HS is chronic. We do not promise cure. We do not push procedures patients don't need. We will tell you plainly when wide-excision reconstruction with a plastic surgery colleague is the better path, and we will help arrange it.
The patient sets the pace
Many HS patients have been rushed, dismissed, or pressured. We work in the opposite direction — written plans, written estimates, time to think, and no schedule pressure at the consultation.

How we practice

What the experience is built to deliver.

Small team, direct access
Dr. Kamrava personally conducts every HS consultation and performs every procedure. The practice operates with a small clinical team so messages reach the right person quickly — not through a call-center maze.
Co-management with dermatology
Most HS patients benefit from dermatologic management alongside procedural care. We coordinate routinely with patients' existing dermatologists and can refer to HS-focused dermatology partners when needed.
Set up for out-of-area patients
A meaningful share of our HS patients fly in. Virtual consultations are part of the standard offering. Pre-procedure logistics, travel windows, and local follow-up handoffs are handled by the team rather than left to the patient.

The broader practice

Other condition-specific programs.

The HS program sits alongside two other focused programs in the same practice: a laser-led pilonidal program and a dedicated anal skin-tag program. The pattern is deliberate — single conditions, deep expertise, honest scope. Each program is separate because each disease deserves its own depth of attention.

Teaching & writing

Continuing engagement with the field.

Active teaching role at Cedars-Sinai. Routine attendance at the annual symposia in colorectal surgery and the international HS research meetings where the laser protocols are being refined. Patient-facing writing on this site, the pilonidal site, and the main practice — the same calm-clinical voice across all of them.

Press, referring clinicians, and patient-community organizers are welcome to reach the practice through the contact page.
