Amber Gussoni, APN is a member of Summit Health's Internal Medicine team. Ms. Gussoni sees adults for everything from routine physical exams focusing on preventative medicine to routine follow-up for chronic conditions as well as Medicare annual wellness exams.Ms. Gussoni enjoys a comprehensive approach to care, working hand in hand with the patient as a team to manage their medical conditions, assist with lifestyle modifications, and coach them through complex disease processes incorporating medical management. Her goal is to provide patients with clear, evidence-based information so they can make an informed decision. This means creating a plan with the patient that they agree with, are comfortable with, and think they can follow. After beginning her career as an emergency room nurse in the fast-paced environment of an ER trauma center, Ms. Gussoni decided to change pace and became a nurse practitioner. "I enjoyed getting to know my patients on a personal level, thus leading me into outpatient internal medicine," Ms. Gussoni says.Nothing is more satisfying than having a patient come back in for a follow-up appointment and witnessing the excitement on their face as they share the success they've made since their last visit, whether it be an improvement in their blood sugar or blood pressure levels, losing 10 pounds, or their newfound commitment to exercising on a routine basis, Ms. Gussoni says.When she's not working, Ms. Gussoni likes to spend time with her husband and their two Jack Russell dogs. She also enjoys exploring new towns, cooking, riding her bicycle, and reading.
