While receiving his Masters and Doctorate from Northwestern University, Philip developed a private studio which he operated between 1972 to the present, giving private, hourly vocal instruction with an emphasis on pedagogical standards, strong breathing, development of tone quality, and maintainance of good vocal health. As well as teaching privately, Philip taught voice at De Paul University from 1993 to 2000. Several of his students went on to both opera company apprentice programs and professional work.

In 1982 Philip was appointed the Director of the De Paul University Opera Theater. Through 1987, he rejuvenated an antiquated program producing highly creative productions of Cosí fan tutte, The Crucible, and an imaginative triple bill of comic French opera including Chabrier's The Incomplete Education, Offenbach's Ba-ta-clan, and Poulenc's The Breasts of Tiresias.

In 1999, Philip was appointed to a similar position at Roosevelt University where his inaugural production of Suor Angelica and Gianni Schicchi received universal approval from the voice faculty, students, and administration. Subsequent productions included full stagings of The Magic Flute and The Coronation of Poppea. At both De Paul and Roosevelt, Philip not only directed all the productions but taught both junior and senior/graduate level classes in operatic stagecraft.

In 2005 Philip was invited to join the faculty of Northweestern University, his alma mater, to teach junior and senior level opera workshop classes and to assist with graduate level scenes classes. At Northwestern, he assists director Noel Koran with all aspects of the opera program.

Throughout his career as an educator, Philip has been fortunate to be able to draw on a wealth of professional experience which he enthusiastically imparts to his students. More than anything, it is the process of education that is the concern in Philip's teaching; a desire to give a student an experience that will vitalize and enhance the learning process.
