Mike,

As Rollo May points out, existential therapy or analysis is not about
techniques per se (with the possible exception of the paradoxical techniques
of V. Frankl which themselves are rooted in an existential framework), as
much a context of human values within which to operate, whether analytically
or otherwise.  So, you have probably correctly observed that some of your
supervisors work BOTH psychoanalytically AND existentially.
