Timothy Griem, LISW
Clinical Manager 

I am a licensed independent social worker. I have been providing mental health therapy to families, couples, adolescents, older persons, and children for over twenty years. I love what I do. I have met people in therapy who have endured much and accomplished some amazing things. I like seeing the talent and abilities in people I meet with. I enjoy creating a relaxed atmosphere for clients where we just kick back and talk about both what is going well and what they would like to have different. My office is unique in that I have many puzzles and drawings on the walls. I tend to have successful outcomes in working with children on the Autism Spectrum. The best part about being a practicing clinician is when I have gotten to know and indirectly be a part of a client's life periodically over a span of many years; somewhat like a family doctor does. Perhaps our paths will cross?

After life and health, a person’s most precious possession is his or her story. It is a privilege to hear a person’s story and help that person deal with various forms of stuckness, such as anxiety, depression, grief, stress, communication difficulties, relational conflicts, and transitions. Bruce is a Licensed Mental Health Counselor (LMHC), a clergyperson, so he has an interest in spirituality. He works with individuals, couples, and families.
