Alba Chacon-Guerra


My name is Alba and my passion is to make people happy. After high school, I was clueless to what I wanted to study. I started noticing that my family was suffering from diabetes, so I felt that the medical field was where I belonged. I completed the Medical Assistant program at Branford Hall in July of 2017. I did my externship at Medi Weight Loss Clinics and was hired as soon as I finished my hours. Working here has taught me a great deal about weight loss and chronic illnesses like diabetes. This has also helped me fulfill my passion in making others happy!
