Our Team

Excuse us, as this page is under construction as we gather bios and photos from our new staff!

DSISD’s leadership team and faculty have a wide variety of skill sets and extensive experiences that range from working in the business and engineering fields to teaching and leading in high-performing public, charter, and innovation schools. We are innovators, and have experience starting schools with personalized learning programs that break the mold of traditional schools by bridging learning to real–world experiences.

Danny Medved- Principal

Danny HeadshotDanny Medved is honored to be the DSISD founding school leader. Before entering the field of education, Danny worked in the business entrepreneurship and outdoor recreation industries, and his undergraduate course work focused on business entrepreneurship and using experiential education as a medium to engage and empower at-risk and underserved students.

Since entering the field of education, Danny has spent his educational career closing the opportunity gap by serving the students of DPS in both charter and Innovation schools.  His work in various DPS leadership programs and the pursuit of his doctorate at the University of Denver in Education Leadership and Policy Studies with a focus on designing schools that utilize a Competency-Based Education approach have prepared him to grow the DSISD founding team and set a vision that will ensure that DPS’s first Competency Based High School is a landmark in school innovation and preparing students to be globally competitive employees innovators.

Outside of work, Danny spends time with his wife Brooke and three children, Havah, Caleb and Rachel, as well as family and friends. The activities that bring their family together tend to involve the outdoors and these range from backcountry skiing to mountain biking. Danny also loves to learn and read.  His favorite novels cross genres and include diverse titles such as A River Runs Through It, Ender’s Game, Invisible Man, and The Grapes of Wrath. Danny’s hope and dream for students at DSISD is simple: that we will empower students to own their learning, so they can effectively pursue their dreams and help shape our society.

Robert Florio- Dean of Culture/ Special Education and Physical Health and Well-Being Teacher

Bob HeadshotOriginally, Bob Florio is from Upstate New York (Schenectady/Albany). Most of his childhood was spent playing sports like wrestling and hockey. After high school he really had no idea what to do with his life, so he joined the Air Force, and graduated basic training on September 8, 2001. From that point on he has been well traveled. He is still in the Air National Guard and trains out of Buckley Air Force Base.

Bob came to Colorado after graduating from the University of South Florida, and teaching at an urban school in Tampa.

Most of his time outside of the classroom is now spent rock climbing, skiing, wrestling, boxing, and doing jiujitsu. He love to tell stories about his life experiences, so feel free to ask him questions anytime.

She attended Cornell University where she competed on the varsity fencing team, and taught rock climbing classes. During her time at Cornell, Madeline took a wandering path through her college education, exploring architecture, art, math, astronomy, engineering, and computer programming in order to discover the space that resides at the intersection of these disciplines where she finally found her home. She also taught rock climbing courses to college students and local community groups. After graduating with a degree in Computer Science and another in Fine Arts, she began teaching math and computer science in Washington DC.

In 2014, Madeline was given the opportunity to join code.org’s curriculum writing team. She spent the next year designing curriculum for a new course, AP Computer Science Principles (a course officially announced by college board later that year) while continuing to teach in DC. She continues to travel around the country working with teachers to help prepare them to teach the course in the next few years.

Madeline was drawn to DSISD because she believes that critical thinking, 21st century skills, and the ability to innovate are necessities for all students leaving high school. She is excited to be in a place where she can help develop learners with these skills. When not in the classroom, she enjoys painting, rock climbing, cooking, and spending time with her husband Caspar, cats, and bearded dragon.

Jeremy Jensen- Lead Math Lead Teacher, 1oth


Kathryn Florance- Math Teacher- 9th 


Caitlin Ross- Lead Social Studies Teacher, AP Human Geography 10th & New Teacher Ambassador

Caitlin HeadshotCaitlin Ross is originally from Rockford, Illinois and earned her B.A. in History and Secondary Education with minors in Political Science and African American Studies at the University of Iowa – Go Hawks! She decided to become a teacher when she first experienced the inequalities of the education system moving from her elementary school to her middle school. It was then she realized so much of how she felt about herself and her learning depended on her teacher and her surroundings so Caitlin chose to be the quality teacher that she always wanted. She has chosen to teach at DSISD because she believes education is not one size fits all, and she knows the only way to ensure each young person has a meaningful learning experience is to empower them lead the way.

Caitlin moved to Colorado to enjoy time hiking and camping, but she is too much of a Midwesterner to ski. She spends most of her evenings doing yoga and cooking new recipes, but her favorite thing to do is to travel.
