Corium was set up by two dermatologists who were tired of a model where the examination is squeezed into ten minutes and everything interesting gets referred somewhere else. We built the practice the other way round.
Every consultation is with a consultant dermatologist — not a trainee, not a nurse working to a protocol. First visits are thirty minutes because a skin history that is rushed produces a diagnosis that is wrong.
We do our own dermoscopy, our own surgery and our own dermatopathology reporting. That is unusual and it is deliberate: when the person who examined the lesion is in the same building as the person reading the slide, questions get answered in an afternoon instead of a fortnight.
What we do not do: package deals, course pre-payments, treatments we have talked you into, or a single laser device sold to every skin type that walks in. If you do not need something, we say so and you go home.

Dr Amara Osei
Skin cancer & dermoscopy lead
MD, FAAD · Board-certified, American Board of Dermatology

Dr Julian Reyes
Dermatological surgery & Mohs
MD, FAAD · Board-certified, American Board of Dermatology
Fellowship-trained in Mohs micrographic surgery and reconstruction. Takes the high-risk facial cases — nose, eyelid, lip — where tissue conservation decides the result. Chairs the practice's skin cancer meeting.
Dr Priya Nandakumar
Pediatric & inflammatory skin disease
MD, FAAD · Board-certified, American Board of Dermatology
Severe eczema, psoriasis and hidradenitis, in adults and children, including the biologic pathway and its monitoring. Runs the patch testing service. Sees children from six months.
Dr Tomas Lindqvist
Laser & procedural dermatology
MD, FAAD · Board-certified, American Board of Dermatology
Vascular and pigment laser, fractional resurfacing, scar revision. Wrote the practice's phototype protocol, which sets device and setting limits for Fitzpatrick IV to VI. Declines more laser courses than he books.
Everything below is at each of the three clinics. Nothing on this list requires sending you elsewhere.
Our own laboratory and reporting dermatopathologist. Slides are read in the same building the biopsy was taken in, which is why five working days is a target rather than a hope.
Procedure room, frozen section processing and reconstruction in one half-day list. AAAHC-accredited ambulatory surgery suite.
Four devices: pulsed dye, long-pulsed Nd:YAG, picosecond and fractional. Having four means the device is picked for your phototype rather than the other way round.
Narrowband UVB cabinet and hand-and-foot unit, with cumulative dose tracked across your whole treatment history — including courses given elsewhere.
Each clinic is registered and inspected under the rules of its own jurisdiction. This is what applies in the United States.
