Christopher Peterson, M.D.

Hi my name is Chris Peterson,
By trade I’m a pediatrician.
Londonderry Pediatrics is my vocation.
Since last century I’ve been in this location.

Prior to this I went to med school
Georgetown taught me well, I’m no fool
From DC I flew north, residency ala Big Green
Honing my skills, learning to listen keen

Now I am qualified to care for your child
My hands are still cold, but my humor is mild
Caring for kids, babies to college
Sickness and wellness, dispersing my knowledge

You may ask, more personally
What’s most precious to me?
I would say more than any degree
Is my cherished wife and family

You may have heard and yes it is true
I have two goats and some chickens too
So this is Chris Peterson in a nutshell.
Time to say g'bye, go in peace and be well.
