  • Biography



    Area of expertise: My areas of expertise are detection and treatment of skin cancer, tailoring the best acne treatment for each patient, mole checks, to find atypical moles and malignant melanoma, and treating resistant warts.

    Philosophy of care/patient philosophy: I consider it a privilege to treat my patients. Like the best relationships, mutual respect and trust lie at the foundation of the practitioner/patient interactions.

    I believe in active listening, learning about the whole person and working with them to achieve their goals.

    I strive to take a detailed history, perform a thorough physical exam, and provide the best treatment available. I take time educating my patients and make sure he/she understands his/her treatment.

    Hobbies: I enjoy playing the piano and watching Major League baseball games.
