Aspen Internal Medicine Consultants, with Ann Mass, M.D. and Paula Kadison, M.D., focuses on the differential diagnosis, treatment and follow-up of adult internal medical problems.  Both physicians also work as hospitalists at Aspen Valley Hospital.  We are particularly interested in addressing complex presentations of disease and work closely with sub-specialists both in and outside the valley.  Our  office schedule is set up to accommodate patients on a same-day basis for acute medical concerns.
