About Us

SWAP offers a comprehensive patient centered approach to sleep/wake health.

We evaluate the co-morbid illnesses in patients with disordered sleep and the bidirectional relationship of these
illnesses with sleep. Rather than only evaluate one problem or organ system, our sleep medicine assessments evaluate the whole of our patients’ medical histories. Sleep-related health problems which we evaluate and consider in the comprehensive assessment of our patients include: cardiovascular, psychiatric, renal, endocrine, respiratory and rheumatologic disorders, as they relate to disordered sleep.

SWAP is a multi-disciplinary health promotion program which provides sleep/wake health education to patients to enhance compliance and encourage then to “SWAP” maladaptive behavioral and psychological patterns affecting sleep, thereby optimizing their physical and mental health.

We also offer in home portable (autoPAP) assessments for obstructive sleep apnea for patients, who are unable to attend overnight in clinic sleep studies.
