CDMG Visits: What to Expect


Our team of specialists is committed to advancing your health by helping you achieve optimal levels of comfort, energy and quality living through a variety of outpatient procedures and treatment. Working in close collaboration with Cooley Dickinson Hospital’s Respiratory Services and Cardiopulmonary Rehab departments, we have the combined experience and expertise to diagnose, treat and manage:

Asthma—spirometry evaluation, FeNO (fractional exhaled nitric oxide) testing, assessment of asthma control and tailored asthma education

Allergies—skin testing as well as allergen, venom and drug desensitization

COPD (Chronic Obstructive Pulmonary Disorder)—pulmonary function testing and interpretation, home oxygen assessments

Pulmonary Nodules—symptom evaluation (FeNO and fiberoptic laryngoscopy), bronchoscopy

Pleural Effusions—thoracentesis

Symptoms—evaluation of symptoms including chronic cough, shortness of breath and lung cancer screening

In addition, our board-certified physicians provide inpatient care in Cooley Dickinson’s Critical Care Unit (CCU) as well as follow-up care (such as tracheostomy management) at our practice. This allows us to partner with CCU patients throughout their recovery.
