Dalton is a native of Castle Rock with deep roots in the community, as a descendant of four generations of Coloradans!

Although this is her foundation, her training has spanned the globe – from the Caribbean to Africa and Ireland!

When not pursuing her passion of practicing medicine, she can usually be spotted around Castle Rock with her husband and three boys in the park or at a local restaurant.  

Don’t be shy to say HI to the doc!
