Elliott O’Melia, PMHNP-BC, psychiatric mental health nurse practitioner in Boulder, Colorado

(Preferred pronouns: He/him/his) 

*Elliott sees patients 8 and up and is available at our Boulder clinic. 

Elliott’s career in mental health started in 2014 as a behavioral therapist for the Wisconsin Early Autism Project, in which he would provide in-home behavioral therapy to children diagnosed with Autism. During that time, Elliott would realize his genuine passion and enjoyment for working in the mental health field. Elliott continues to appreciate this realization, and the purpose that working in the mental health field provides him. 

Elliott has a particular passion for treating ADHD but also treats patients experiencing many mental health concerns, including anxiety, depression, grief, bipolar disorder, and life transitions.  

One of Elliott’s favorite aspects of being a Psychiatric Nurse Practitioner includes getting to know the individual.  

Elliott believes that we never forget the people that were there for us when we ask for help. Working in psychiatry, Elliott appreciates this amazing opportunity to be remembered as that very person. He sees it as an incredible honor when someone puts faith in him and his ability to support them, knowing how difficult initially sharing a vulnerability with a stranger may feel. This is an honor that Elliott never wants to take for granted. Some of the most powerful moments of his life he attributes to his work in the mental health field, and he knows he wouldn’t be who he is today without those moments.  

Elliott enjoys being active in his free time which includes tennis, running, weightlifting, and skiing. Born and raised in Wisconsin, Elliott carries with him to Colorado a strong passion for the Green Bay Packers, Milwaukee Bucks, and cheese curds.
