Described by The Washington Post as a “dazzling virtuoso,” Daniel Lelchuk is renowned worldwide as both a cellist and a communicator. He has performed in numerous international festivals, including in Aspen, Baden-Baden, Hawaii, Colorado, the Minnesota Lakes Area, Silicon Valley, and Salzburg. He has been guest cellist with the Qatar Philharmonic, guest principal cellist of the Orquesta Filarmónica de Jalisco, cellist with the Orquesta Sinfónica de Minería (Mexico City), and principal cellist of the Royal Opera House Muscat (Oman). For a decade, Lelchuk was Associate Principal Cellist of the Louisiana Philharmonic Orchestra and the New Orleans Opera Association, appointed by Music Director Carlos Miguel Prieto. At the invitation of Prince Nicolò Boncompagni Ludovisi, he presented a celebrated series of solo cello recitals at the historic Villa Aurora in Rome.

From 2010 to 2014, Lelchuk served as principal cellist of the Castleton Festival under Maestro Lorin Maazel, performing major solos from the operatic and symphonic repertoire, to critical acclaim. Since 2016, he has been principal cellist of the New York-based Salomé Chamber Orchestra, regularly touring internationally with violinist David Aaron Carpenter and the ensemble. He also appears as cellist of the Aegis Trio with violinist Daniel Kurganov and pianist Constantine Finehouse.

For the past decade, Lelchuk has served as a fine instrument consultant for Carriage House Violins in Boston, matching musicians with their ideal instruments, including exceptional examples by revered makers such as Stradivari, Grancino, and Postiglione, as well as master bow makers including Tourte and Sartory.

An accomplished administrator, Lelchuk founded the Festival de Música de Cámara Antigua (Antigua Chamber Music Festival) in 2023, the first major chamber music festival in Guatemala. As Artistic Director, he brings world-class musicians to Antigua each winter, presenting acclaimed chamber concerts. Lelchuk is a founding member, alongside violinist Eric Silberger, of the Castleton Chamber Players. They present chamber music concerts in the "jewel box" Theatre House designed and built by Maestro Maazel, often collaborating with distinguished artists like Orion Weiss, Michelle DeYoung, and Paul Groves. Committed to the future of music education, Lelchuk developed the cello curriculum for tonebase, the premier online music education platform, where he served as Head of Cello Content. Beyond designing the platform's cello content, he hosted regular worldwide livestreams and cultivated an online community connecting thousands of diverse and passionate cellists globally.   Lelchuk’s writing on cultural matters has appeared in major publications such as The Bulwark (as a contributing writer), Quillette, and The Forward, championing the accessibility of classical music or introducing readers to specific works by composers like Puccini or Schoenberg.

An avid road cyclist, he spends as much time as he can on two wheels.
