Bernadette Collazo, MSN, FNP
Bernadette was born in Laredo, TX as one of 9 children. She had 4 brothers and 4 sisters. She worked hard to advance her career, achieving her BSN from UTMB School of Nursing, and her Masters in Nursing and Family Nurse Practitioner degree at UT Health Science Center at San Antonio.
Bernie has been a nurse practitioner for 14 years in a variety of practices. She worked in family practice until 2005, when she made the transition to diabetes as a specialty.
There are several people in Bernie’s extended family that are affected by diabetes and she has seen relatives go through many hardships from diabetes complications. She feels that if she can help someone prevent those hardships, she is rewarded. Diabetes is a constant battle!
Bernie joined DiabetesAmerica and believes we provide a unique service. She has worked in other environments where patients were seen with little time and very little educational support. With providers and educators, patients at DiabetesAmerica will have the tools (medications, education, diet and lifestyle coaching) that they need to manage their condition.
Bernie is married to a pharmacist, Jesus, and they have 3 children, Ashley, Aaron and Joseph. She loves to read and also spends time watching her kids participate in softball and baseball games.
