Care Philosophy

Exceptional medical care is a marriage of knowledge, concern, and communication. Patient care should extend far beyond lab work and medication. I believe in preventive health care and issues concerning life style, stress, and mental health, with special interest in anxiety and stress-related illness.  I also enjoy my work with adolescents and men's health issues.

Care Philosophy

Attention to detail, with complete patient participation and patient education is essential to providing excellent medical care. I want my patients to feel comfortable discussing any and all of their concerns about health issues with me and to know that their problems are my chief concern. I am interested in primary care with an emphasis on preventive health, cardiac health and cancer screening. I also have special interests in women’s issues, diet, and travel medicine.
