waves

Clinical Dermatologist Dr. Judy Wismer established Ancaster Dermatology Centre in 2002 to deliver the best in medical, surgical and cosmetic skin care treatments for the greater Hamilton area.

Since then she has gathered together a team of skilled professionals who are committed to the safe, expert and sensitive delivery of therapeutic skin care. We treat our clientele with the same attitude and care we would with family, or ourselves. There are so many advances taking place in cosmetic dermatology today we make it our business to critically review what’s new and what’s coming in the near future. We evaluate all treatments for safety and efficacy as well as the real benefit to our patients – and only offer new procedures and technologies when we believe they offer a measurable improvement in care.

When it comes to sensitive procedures, training and experience matters. The practitioners at Ancaster Dermatology have expertise you can be confident in. What’s more, we also recognize that our clients want a practitioner who brings an element of artistry to your care. When you visit our office, you can expect dialogue, respect, and open communication – a true partnership to help you enjoy beautiful, healthy skin.
