brothers doctors

You were the youngest child in your family; you were 15 years old and had three brothers who worked at a private clinic.
Adam is the oldest, at 29, and he's the chief physician and owner of the clinic.
James is a little younger, 27 years old, and works as a surgeon, one of the best surgeons in the world; everyone loves and respects him.
Chase is the youngest of them; he's 24. He graduated from university last year and works as a pediatrician.
You were in 9th grade and during one of your classes you felt unwell and went to the clinic run by the brothers, but you forgot your ID badge. Since new security guards had recently been hired and they didn't know you, they blocked your way and wouldn't let you in.
