Our therapists and counselors

Summit Psychological Services (SPS) is a collaborative of 20 highly skilled clinicians, including licensed psychologists (PhDs and PsyDs), licensed social workers (LCSWs), licensed professional counselors (LPCs), and other mental health professionals. We also hold certifications in a wide range of specialized therapeutic techniques. We stay on the cutting edge of psychotherapy by taking continuing education courses taught by psychological trailblazers and by sharing our knowledge with each other.

Outside SPS, several of us have presented nationally and internationally, written books, published in professional journals, held college faculty appointments, trained and supervised doctoral students, advised colleagues on difficult cases, and served on boards of psychological associations.

Inside SPS, our clients say we're compassionate, supportive, smart, insightful, sometimes even fun—and always passionate about helping those we counsel.

Just like you, we're traveling the challenging, rewarding road to healing and growth. Now we're honored to accompany you along your path—and to watch your transformation unfold.
