Health Information

Colon Testing

Colonoscopy is a procedure used to examine the inside of the colon and rectum for abnormalities. Colonoscopy is generally considered the procedure of choice to look for early signs of colorectal cancer. Ask your physician if you should have this important screening exam.


Pregnancy Care

Pregnancy is an exciting time in a woman’s life. Medical care should begin several months prior to becoming pregnant to discuss risk reductions and proper supplementation. Care continues throughout the 40 weeks of pregnancy and 6 weeks after the birth of your child. We also provide newborn and pediatric services for your new little one. Call now to schedule an appointment if you are thinking about pregnancy or are already pregnant, 970-241-7600.



There are a wide variety of options available to prevent pregnancy. These include traditional pill forms, injections, vaginally inserted rings, intrauterine devices, an implantable device in the arm, and permanent forms of contraception. For information on any of these methods or to schedule an appointment call the office, 970-241-7600.
