Meet Our Staff


Mike Fratangelo


Co-founder Mike “Sunshine” Fratangelo is renowned for his upbeat personality and innate ability to keep the camp Gatorade chilled at precisely 32.5 degrees. Mike graduated from Haverford College in 2007 and earned his Masters degree from Bryn Mawr College in 2009. Upon graduation, Mike had the incredible opportunity to play professional basketball in Europe and the Middle East. In addition to coaching hoops, Mike’s interests include reading, problem solving, and perfecting his wide array of boy band dance moves of the early 2000s era. Mike is thrilled to work with the amazing staff and campers who make DiverseCity Hoops such a special experience every summer!


Greg Rosnick


Greg Rosnick, a DiverseCity co-founder, graduated from Haverford College in 2009 and continued on to receive his Masters in Teaching from Smith College in 2010. After finishing graduate school, Greg taught English and coached basketball in Athens, Greece and is now the assistant Men’s Basketball Coach at Colby College. In his spare time, he likes to consume TV and books about sports and education, hang out with his dogs, and translate ancient texts into Portuguese – just in case he might need it one day.


Sam Permutt

Program Director

Sam Permutt, also known as “Sammy Vert”, spent nine years with DiverseCity Hoops. After graduating from Haverford in 2011 with a degree in economics, Sam had the opportunity to continue his career in Israel. He currently teaches middle school and coaches high school basketball at St. Andrews School in Delaware. He particularly enjoys working with young people, as well as watching The Wire, freestyle rapping, food, and blowing his whistle while telling people to rotate stations. Known for his abundance of energy and enthusiasm, Sam was once asked by a camper, “Why are you so positive all the time?”


Justin Herring

Baseball Program Director

Justin Herring, commonly referred to as “The Showstopper”, is a 2018 Haverford College graduate from Douglassville, PA. He was a four year member and senior captain of the Haverford College baseball team, earning an All-American accolade during his career with the Fords. Justin takes both baseball and social issues seriously, writing his senior economics thesis at Haverford on racial discrimination in Minor League Baseball. He is known for his ability to keep the mood light with both well-timed and very poorly timed jokes. He has been perplexing DiverseCity campers since he joined the staff in 2016 with the question, “How tall do you think I am?” The closest guess to date is “10 feet 5 inches.”


Abby Harrison

Media Coordinator and Program Manager

Abby Harrison is a current student at Haverford College, set to graduate in 2019 with a degree in Geology. She is a Maryland native, but has since fallen in love with Philadelphia since moving there in 2010. Abby has always been an athlete, and spent 14 years playing soccer before switching to track and cross country in college. She will never back down from a challenge, wether it be on the field, in the classroom, or in the dining center, having made waves her first summer as being a controversial proponent for the idea that “peanut butter just goes on everything.” Her time at DiverseCity has been spent creating photo and video content for the program, which she loves due to the ability to capture both heartwarming teamwork moments and basketball skills that are straight fire. 


Caroline Feldman

Program Director

Caroline Feldman is a 2005 graduate of the Shipley School and a 2009 graduate of Haverford College, where she received her B.S in Biology. While at Shipley, Caroline set and still holds the record for the most 3-pointers (46) made in a single season. At Haverford, she lettered for the women’s basketball team for three years and decided her senior year that she wanted to try coaching. She returned to her high school alma mater, Shipley, to assist the varsity women’s basketball team to a Friends’ League championship. Caroline currently is employed by the Shipley School, where she teaches 8th grade science and coaches middle school soccer and basketball. Caroline has been working at DiverseCity Hoops for the past seven summers, where she has coached her team to a championship multiple times (only lost twice). She is looking forward to continuing the “Feldman” dynasty in summers to come.


Colin Castro

Program Manager

Colin Castro is in his fifth summer with DiverseCity Hoops. He is affectionately known as one of the ‘OG’ athletes at DiverseCity, attending three summers and racking up two camper of the week awards during his time as a camper. Colin is a graduating Senior at the College of William & Mary, studying business analytics. In his free time he plays on the club basketball team, volunteers in a local neighborhood and works in the school’s athletics department. Around DiverseCity, Colin likes to bring energy and versatility to his multiple roles. Whether it’s leading the defense station, give a rousing leadership lecture or doing Michael’s dishes in San Francisco, he truly enjoys being part of the DCH team.



Steve Breaston

Program Director

University of Michigan alum (Go Blue!), Steven Breaston is a former NFL wide receiver and all-around great guy! Breaston, a Pittsburgh native, understands first-hand the value that healthy communal programs have on children. With a long list of professional accomplishments and accolades, Steven’s real passion lies within community outreach, philanthropy, and working with kids. Steven reserves his spare time for movies, all things Marvel and DC related, and of course, serving up buckets. When asked for a comment, Steven replied “No question.”


Adrian Takyi

Program Manager

Adrian Takyi has been a part of DiverseCity Hoops since 2011 and is brought back every year by the great kids, positive environment, and incredible team handshakes. An upstate New York native, Adrian graduated from Haverford College before working in the Philadelphia area as a teacher and basketball coach. Now living in Oakland, Adrian spends his time teaching 2nd grade, watching the NBA, and searching for the world’s best sandwich. He can’t wait to watch the DCH community continue to grow!


Nat Ballenberg

Baseball Program Director

Nat Ballenberg was born in Boonton, NJ and has been playing baseball his entire life. A sophisticated Google search may reveal hours of home video of 2 year-old Nat smashing line drives with his plastic red bat, throwing a changeup over the backstop at age 10, or, as a teenager, getting thrown out at first base on clean single to right field. The accolades don’t even stop there. He was voted Most Gullible by his high school graduating class, and in college he earned the name G-Nat – like the bug, which not coincidentally was his nickname during his season of professional ball in Israel. After returning from playing and coaching in Germany, Nat became the assistant coach at Haverford College, where he has brought his unique combination of hard work and silliness to a team that truly embraces that dichotomy. He likes baseball, protein bars, and anything that makes him laugh.
