Denise Cutkelvin Heern

Restorative Practice Coordinator (RJ)
d_cutkelvin-heern@dpsk12.net

My name is Denise, and I serve as the Dean of Discipline and Restorative Practices at Colfax Elementary. A native New Yorker, I’ve called Colorado home since 2018 and have proudly worked with Denver Public Schools since 2022. With a background in Forensic Psychology from John Jay College of Criminal Justice, I bring a deep understanding of behavior, empathy, and accountability to my role.

Having started as a Special Education paraprofessional and now serving as Dean, I am committed to fostering a safe, respectful, and inclusive school environment where every student has the opportunity to thrive. As both an educator and a DPS parent, I am deeply invested in creating a school culture that values relationships, encourages growth, and supports restorative approaches to discipline. I believe in working collaboratively with students, staff, and families to build a community rooted in trust, dignity, and shared responsibility.

About Me:

I am excited to be joining the Colfax community as a School Social Worker this year! I graduated with my MSW in 2024 after a career change from human resources and account management. The switch to social work has been both challenging and highly rewarding, and I am happy (and lucky) to be doing something that I truly care about. I look forward to being a part of the Colfax community and watching students grow their skill sets and knowledge.

Marcia Small

Guest Teacher
msmall@dpsk12.net

About Me:

My name is Marcia Small. I am a retired DPS Dance/Physical Education teacher. I taught one year at East High School, ten years at North High School and finished my teaching career at South High School where I taught for sixteen years. When I retired eight years ago I quickly became extremely bored and so I started guest teaching. Since my son, Cole Hydrick, was already teaching at Colfax Elementary I quickly adopted Colfax as my favorite school for guest teaching.

Over the years, Colfax has become my second family because I know all the wonderful, hard working staff and the amazing students! The students call me Ms. Small, Ms. Marcia, Ms.Tiny or Mr. Hydrick’s mom.

About Me:

This is my first year at Colfax Elementary School. I am a bilingual mental health professional with a Master’s in Social Work from the University of Denver. My clinical experience includes working with Spanish-speaking clients at SOL Mental Health and SALUD Family Health Centers. I work for Centus counseling, consulting, and education to provide therapy to students and groups. My approach is strengths-based—I believe in identifying what’s working and building from there while helping students and families navigate challenges with compassion and skill. I draw from a range of evidence-based modalities, tailoring my methods to meet each student’s unique needs. I aim to help students achieve academically and socially.
