Featured Services
Mohs Surgery (On-Site Skin Cancer Removal)
Mohs surgery spares the most amount of normal tissue and has the highest cure rates for many non-melanoma and melanoma skin cancers. It’s the gold standard of care in non-melanoma skin cancers and is commonly used in the treatment of some melanomas.
Patch Testing
Have you ever had a rash that just wouldn’t go away? Many people don’t know they have an allergy because reactions are often delayed. Patch testing involves applying a purified allergen to a person’s skin to see if it causes an allergic reaction.
Biopsies
A biopsy is the removal of a piece of skin to help render a diagnosis of skin cancers or inflammatory conditions. Dermatologists biopsy an area to confirm a diagnosis that cannot be rendered with the eyes alone. We need a microscope to be certain.
Excisions
Skin excision is a surgery where we cut out damaged skin tissue. It is a full-thickness removal — meaning we remove all layers of the tissue (epidermis, dermis, and into the subcutaneous fat layer). We then suture it back together with stitches for optimal healing.
Skin Care Screenings
Skin cancer doesn’t discriminate. Anyone can get skin cancer, whether young or old, fair or dark, and it’s the most common type of cancer in the United States. Most people should have a professional skin examination once a year.
Acne Treatment
Acne can have a big impact on your life, which is why we take acne treatment very seriously and use aggressive treatment plans when necessary. Our staff is passionate about treating acne to prevent the emotional and physical scars that can last a lifetime.
Rashes
A rash is an abnormal change in your skin’s texture or color, usually characterized by a red, scaly irritation on your skin. Because of the sheer number of rashes and their subtle differences, specialized training is required to properly diagnose and treat rashes.
Psoriasis
Psoriasis is an inflammation in the skin driven by the body’s own immune system. The inflammation in the skin causes red, itchy, and scaly lesions mainly around elbows, knees and scalp. While not contagious, it’s important to seek the help of a dermatologist.
