Conejo Dermatology is a comprehensive medical, surgical, and cosmetic dermatology practice in Thousand Oaks, California including Board Certified Dermatologists Ralph M. Kamell M.D, Michael G. Bodnar M.D., and Jeanette K. Mitchell M.D., and William E. Rietkerk M.D. Our dermatologists have received exceptional training and stay continually updated with most recent advances.

Our General Medical Dermatology services include care of skin, hair, and nail diseases affecting patients from all ages and stages of life. We evaluate and treat growths including moles, birthmarks, keratoses, and generalized sun damage, including full body skin exams for early detection of precancers and skin cancers. We also manage acute and chronic rashes including allergic conditions, autoimmune conditions, acne, rosacea, eczema, psoriasis, seborrheic dermatitis, infections, warts, and molluscum, and disorders of skin pigmentation, hair, and nails.

Our Dermatologic Surgery services include excision of benign, precancerous and malignant skin lesions for diagnosis and treatment. We also offer Mohs Surgery when indicated for skin cancers on the head, neck, hands, feet, or for aggressive, large, or recurrent skin cancers on areas where tissue-sparing is as important as complete cure. We take pride in our attention to detail, top notch training, and experience which enable optimal reconstruction of surgical defects with excellent cosmetic results.

Our Cosmetic Dermatology services include treatment of skin discolorations and unsightly growths by all three doctors; Dr. Kamell and Dr. Bodnar offer facial rejuvenation including treatment of fine lines and wrinkles with injectable products including Botox and Dysport as well as fillers including Restylane, Perlane, and Juvederm. Dr. Kamell also offers chemical peels as well as IPL treatment of facial discoloration and blood vessels using the Vasculight laser. Dr. Kamell also offers treatment of varicose veins using sclerotherapy.
