Hannah Hammel Maser joined the Detroit Symphony Orchestra as Principal Flute in January 2020. Before joining the DSO, Maser held the position of Principal Flute of the Knoxville Symphony Orchestra from 2017–2019. An active chamber musician, she frequently curates and performs recitals with her DSO colleagues and has performed with chamber music organizations including Detroit Chamber Winds and Strings and New Music Detroit.

As an orchestral musician, Maser has performed as guest Principal Flute with the Pittsburgh Symphony Orchestra, Toronto Symphony Orchestra, and Baltimore Symphony Orchestra, and also as a guest in the sections of the New York Philharmonic, Fort Worth Symphony, Nashville Symphony, Houston Grand Opera, Richmond Symphony, New World Symphony, and the Cleveland Orchestra, including as a guest with them on a tour to Austria. Maser has attended summer festivals including Tanglewood Music Center, Music Academy of the West, Pacific Music Festival, Spoleto Festival USA, and Round Top Music Festival.

Maser joined the Flute Faculty at the Cleveland Institute of Music in 2024 and served as acting Assistant Professor of Flute at Michigan State University during the spring semester of 2023. Maser is a sought-after teacher and orchestral excerpt coach and has been invited to teach for the Oberlin Conservatory, Cincinnati College-Conservatory of Music, University of North Texas, University of Alabama, University of Michigan, and Interlochen Arts Academy. Maser regularly coaches flutists through the Sphinx Organization and was a coach for Sphinx's 2022 Audition Intensive with the New World Symphony. Maser maintains an active private studio in Detroit and a robust virtual flute studio, consisting largely of advanced flutists auditioning for professional orchestras. Maser is also enthusiastically involved in DSO community engagement performances and educational outreach programs, including regularly working with youth orchestra members of the Civic Youth Ensembles and adult flutists in the Detroit Community Ensembles.

Maser has been featured as a soloist with the DSO on numerous occasions, including performances of Carl Reinecke's Flute Concerto, Bach's Brandenburg Concerto No. 5, and a world premiere of Jeff Scott's Paradise Valley Serenade for wind quintet and orchestra. As a student, Maser won first prize in the National Flute Association's Young Artist Competition, with special distinction given for the Best Performance of the Newly Commissioned Piece, and the Orchestral Excerpt & Masterclass Competition and is the only flutist in NFA history to have won all three honors. She also won first prize in the Houston Flute Club Byron Hester Competition, the Atlanta Flute Association Young Artist Competition, the Central Ohio Flute Association Collegiate Division Competition, and second prize in the Mid-South Flute Society Young Artist Competition. An active member of the National Flute Association, she now serves as the Competition Coordinator for their Orchestral Excerpt & Masterclass Competition.

A native of Richmond, Virginia, Maser began studying the flute with her mother, Alice Hammel. She holds a Bachelor of Music in flute performance and a minor in music theory from the Oberlin Conservatory (2015) where she studied with Alexa Still. She graduated with a Master of Music in flute performance in 2017 from Rice University's Shepherd School of Music as a student of Leone Buyse.

Maser plays on an 18K gold Muramatsu flute and a Keefe piccolo. She lives in Huntington Woods with her husband, Ian, and their two labradoodles, Evelyn and Cooper.

Jack Walters joined the Detroit Symphony Orchestra in 2017 appointed by Music Director Laureate Leonard Slatkin. In 2016, he was awarded the Zarin Mehta Global Academy Fellowship with the New York Philharmonic. He has also performed with the New World Symphony in Miami. In the summers of 2016 and 2017, Walters was a festival participant at the Music Academy of the West as a recipient of the Spencer and Myra Nadler scholarship and has also attended the Texas Music Festival and the Kent Blossom Music Festival.

After completing his bachelor’s degree from the University of Michigan under the tutelage of Dan Gilbert and Chad Burrow, he attended the Shepherd School of Music at Rice University studying with Richie Hawley. His other primary teachers include Craig Lawrence and Sean Osborn. Walters is a D’Addario artist and plays exclusively on Reserve Classic reeds.

Will Haapaniemi is a violinist born in Los Angeles with Finnish ancestry. He joined the Detroit Symphony Orchestra in 2014 alongside his wife and violinist Heidi Han. Haapaniemi wanted to be a violinist from the time he was two years old, when he saw Itzhak Perlman perform on Sesame Street. Many other interests competed with his practice time—some of his favorites being the martial art Capoeira, dance, and training for his glider pilot license.

Much is owed to Haapaniemi’s master violin teachers, Yoko Takebe and Michael Gilbert of the New York Philharmonic, who he studied with at the Manhattan School of Music. In high school, Haapaniemi was fortunate to study with Mark Kaplan and fondly remembers lessons with Ruggiero Ricci in his home in Palm Springs. Also of great influence was his cousin Paul Roby of the Philadelphia Orchestra and his aunt Linda Grace, whose tireless support encouraged him to be the musician he is today. Without the phenomenal support of Haapaniemi’s parents, none of this would have been possible.

Haapaniemi is active as a soloist and chamber musician, occasionally throwing viola into the mix. An avid outdoorsman, he hikes at every opportunity, and pays homage to his Finnish heritage by skiing during the winter.

Jeremy Crosmer is a remarkable artist—both as a cellist and a composer. He completed multiple graduate degrees from the University of Michigan in cello, composition, and theory pedagogy, and received his DMA in 2012 at age 24. From 2012 to 2017 he served as Assistant Principal Cello with the Grand Rapids Symphony and joined the Detroit Symphony Orchestra in May of 2017.

Crosmer is the composer and arranger for the GRS Music for Health Initiative, which pairs symphonic musicians with music therapists to bring classical music to hospitals. In March of 2017, the Helen DeVos Children's Hospital launched a music channel that runs continuously, using four hours of meditative music composed by Crosmer and performed by musicians of the GRS.

Crosmer is a founding member of the modern music ensemble Latitude 49. He is also a current member of the band ESME—a duo that aims to broaden the education of classical music by bringing crossovers and mashups of pop and classical music to schools throughout Michigan. ESME released its first CD in December of 2016.

In April of 2013, Crosmer toured London with the Grand Valley State University Chamber Orchestra performing the Boccherini G Major Concerto, No. 7. He performed the Vivaldi Double Concerto with Alicia Eppinga and the GRS in March of 2016. While still in school, Crosmer was awarded the prestigious Theodore Presser Graduate Music Award to publish, record, and perform his Crosmer-Popper duets. He recorded the duets with Julie Albers, and both sheet music and CD recordings are available online.

Crosmer has taught music theory, pre-calculus, and cello at universities across Michigan. He draws mazes, writes science fiction, and plays good old country fiddle in his spare time.
