Vice President

Rob Rehburg

Rob Rehburg’s love of music began as soon as he could tap his baby feet. A Denver native, Rob started singing and dancing for audiences in featured roles in elementary school plays, his senior year Spring Musical – The Pirates of Penzance – in high school, and now with many professional theatre companies in the Denver metro area. Some of his favorite roles include Hero in A Funny Thing Happened On the Way To the Forum (Vintage Theatre), Action in West Side Story (Town Hall Arts Center), and Bobby in A Chorus Line (Ignite Theatre). Rob’s instrumental music career also began in elementary school when he experienced an Inside The Orchestra school assembly. Though he fell in love with the sound of the French Horn, it was not offered at the 5th Grade beginner level, so he opted for Trumpet. Rob stayed with the Trumpet through middle school and then discovered his love of marching band in high school. Growing in his passion for marching and leadership, he became the Drum Major and served in that role during his junior and senior marching seasons. At the University of Colorado Denver, he achieved a minor in Performance Music with an emphasis in Trumpet. Though he minored in music, Rob majored in Business Administration, which has ultimately lead him to his current position as the VP of Operations for one of the premier manufacturer’s representative firms for boilers and water heaters in the Colorado/Wyoming territory – IDC Associates. He has built his career in the industry for over a decade. He is excited to bring his harmonious mix of left-brain and right-brain interests and experiences to the Inside the Orchestra board.

Cindy Bedard

Having grown up with two concert pianists in my family, I developed a love of music at an early age. With two young boys of my own, I discovered Inside the Orchestra through the Tiny Tots program and was moved from the first performance. I am committed to helping the organization succeed and expand so that others can learn and enjoy the value of the music and fine arts at any age. I believe music can be so accessible no matter what age or demographic a person is, and I am honored to be part of an organization that makes spreading the joy of music possible. In my day-to-day life, I am a mom of two young boys and a finance professional working part-time.


Jean Plotkin

The arts have played a huge role in my life, and I can personally attest to the positive impact a musical education can have on one’s academic, social, and professional success. I started playing the tuba in fifth grade, and the persistence, discipline, knowledge, and skills I learned in concert and marching band transcended all of my other subjects, helping me to excel across the board both in and out of school. After receiving my Bachelor of Arts degree in Environmental Studies from St. Lawrence University, I moved to Washington D.C. and joined an environmental consulting company where I specialized in communications and event planning for government agencies and non-profit organizations. In 2011, my husband and I moved to Denver (I’m originally from Pennsylvania, but he’s a Colorado native), and I left my job of nearly eight years to become a full-time mom to my two wonderful children. We love exploring our city and state and taking advantage of all the amazing experiences it has to offer—including Tiny Tots concerts! I am a firm believer in programs that expose children to music from an early age and that encourage them to make music a part of their lives. Inside the Orchestra is an extraordinary program that will help achieve these very goals, so I am delighted and honored to join its Board of Directors. I want all kids to have the same opportunity to fall in love with and benefit from music and the arts that I did.

My passion with music began in 5th grade on a school trip to the orchestra.  It led me on an amazing adventure.  As a trumpet player, I learned not only how to play an instrument, but also made lifelong friends, learned the importance of teamwork, and maybe how to think differently.  I was able to play with the Blue Knights Drum and Bugle Corp and went to the University of Colorado on a music scholarship.  This is my dream for any child who chooses to pursue music.  As a parent of two young children, I hope for early and frequent exposure to music of all kinds, including the live orchestra experience provided by Inside the Orchestra’s outreach programs.  I feel very fortunate to be involved with Inside the Orchestra and look forward to an exciting future.  My wife and I are both Colorado natives and it brings us great joy to see how this organization keeps music alive in the hearts of our children.

Originally from Iowa, I moved to Colorado in 2011. I instantly fell in love with the mountains, the people and everything about the state. Shortly after moving here, I opened up my own estate planning law firm. I have an enormous love for everything outdoors and have always felt the need to give back to the community in both my personal and professional lives. When I first joined Inside the Orchestra, I was simply looking for a place to volunteer. What I have received in return is more than I could have ever asked for. The children I get to directly help and the testimonials I receive from parents through this organization have changed my outlook on every aspect of my life. People often ask me, why children? My answer is simple and the same every time. Without children that are inspired to succeed, without children who have educational opportunities to become doctors, scientists and engineers, without children who grow up wanting to fight for a cause, none of these other great organizations would exist. It all starts with a child who is given the opportunity to succeed. That is what this organization has done for me – it has given me the will and the opportunity to succeed. I do my best to give that opportunity back to everyone I meet and work with on a daily basis.I owe a huge thank you to Inside the Orchestra and the children it serves.

Kate Stobbe

I am a recent transplant to the Denver area from Chicago, IL. In Chicago, I worked in corporate responsibility for several different companies with an emphasis on corporate philanthropy and sustainability. While my professional passion lies with helping companies become responsible members of the communities in which they operate, my personal passion lies with the arts. I started playing the cello in sixth grade and continued through college and beyond. My orchestral experience brought me on international tours to Canada and Austria and taught me the importance of listening to the subtleties when playing in a large orchestra (which I also use in my work life!). It is this passion and personal experience with music that spurred me to join the board of Inside the Orchestra. While I grew up listening to classical music, I didn’t see my first orchestra performance until middle school. With a young daughter of my own, I know how vital early arts exposure is for children. I am very excited to be part of an organization that brings such an interactive and interesting music experience to even the youngest of audience members.

Sean Smith

I am an avid music lover, traveler, and reader. As I have not yet found a way to transform those passions into a way to pay the bills, I have opted to work in the financial services industry for the last decade both in New York and overseas before moving to Denver. Music and the arts have played an increasingly large role throughout my life. I, along with most of my peer group, began playing the recorder when I was eight years old. After quickly advancing to the tenor recorder, I sought greener pastures with the violin and then the tenor saxophone. Once I hit my rebellious teenage years, I picked up the guitar and bass guitar and have stuck with those since. I joined Inside the Orchestra because I believe that giving children access to music at an early age opens doors which would not otherwise be explored. Although my music tastes have settled somewhere in between obscure blues and New Orleans jazz, this path all started with the basics which I learned on the recorder. I am excited to help the organization bring this engaging music experience to these students and truly open the door to the possibilities which music has to offer.
