Sherry Guthrie Petoskeky Professional Counselors

Sherry Guthrie M.S., LPC
Practice Owner

Sherry Guthrie M.S., LPC received a Master of Science in Clinical Psychology from Barry University in Miami Florida in 1998 and has been working with clients from all walks of life for nearly 25 years providing quality, ethical services. Sherry has enjoyed working in large community centers, in private practice settings and have supervised clinical programs. She is a past contributor to both  “Being” magazine and the Petoskey News Review. Sherry also served as Adjunct Faculty at Miami-Dade college for 7 years before relocating to Petoskey Michigan in 2007.

In Sherry’s own words: “I work with individuals who wish to live a full and rewarding life regardless of past experiences or current challenges. My clients have a range of issues including depression, anxiety, recent or remote trauma, childhood maltreatment, family dysfunction, women’s issues, distortions of thought, or grief and loss.  I use a variety of carefully chosen modalities to assist clients in reaching their personal goals. Such modalities might include CBT, traditional talk therapy, relaxation, biofeedback, pyscho-dynamic interpretation, assessment measures, and reading or writing material.

Making changes is never easy. It takes purposeful effort both inside and outside the therapy environment. Many clients find personal growth both difficult and rewarding. Therapy is not a sprint, it means learning new techniques for living and continuing to hone these techniques long after the therapeutic relationship has ended.”
