Our Professionals

Our goal is to meet the needs of our local community as well as to contribute to our broader professional communities. Portland, Oregon is a unique city – outstanding in its community building efforts. We aim to work with our remarkable hospital providers in Portland, and through strong consultation relationships, offer psychological services where needed. Furthermore, we are integrated in a community within a community in the South Waterfront and evaluate the needs and requests of this community as well. On a broader scale, we work nationally through various activities to further our specialized fields.

Our Psychologists & Trainees

Our psychologists, psychologist residents, and practicum students in psychology doctoral programs specialize in psychotherapy, research, teaching and supervising. In clinical practice we assist clients as they develop strategies for coping with new or chronic health conditions, physical or cognitive rehabilitation, and/or degenerative disease, terminal illness, dying, and adjustment to loss. Our professional work considers individuals’ and families’ deeply meaningful and existential experiences about life and death. At times the goals of treatment might include addressing elevated or new symptoms of anxiety, depression, Post Traumatic Stress Disorder (PTSD), sleep difficulty, and/or chronic pain, while at other times treatment will focus on helping clients and loved ones to make sense of all that has happened or is happening. We work collaboratively with other medical and health care providers in order to best treat the whole person. Our practice emphasizes the highest standards of privacy, respect, and dignity for all of the clients whom we serve.

Louise E. Marasco, Ph.D.

Dr. Marasco, licensed clinical psychologist, founded Transitions Professional Center. She completed her Ph.D. in clinical psychology at Palo Alto University in California and completed her pre-doctoral internship at the Miami VA Healthcare System in Florida with specialized training in geropsychology. Following internship, she completed a palliative care post-doctoral Fellowship at the VA Palo Alto Health Care System with training emphasis in inpatient hospice care, extended care, palliative care and palliative care consult service. All programs were APA-accredited, meeting the highest standards and guidelines for psychology training programs in the US.

Dr. Marasco’s areas of specialties include work with adults and older adults facing impending loss, who are actively dying, and who are bereaved. Areas of training experience  include evaluation and treatment of clients with spinal cord injury, pre- and post-heart transplant, PTSD, and severely mentally ill. Her academic and clinical training includes an emphasis in neuropsychological assessment in adults with various etiologies, including traumatic brain injury, dementia, stroke and other vascular disorders. Much of her clinical training was established with inpatient and outpatient veterans and their families, and experience in a county inpatient psychiatric facility. Louise’s research focus has also revolved around loss, including loss of a perinatal baby.

Dr. Marasco’s career in palliative care, end-of-life care and bereavement initially grew out of interest in cultural and religious differences in customs and beliefs around death and dying. During her studies of Buddhism, she simultaneously worked as a home hospice volunteer for several years. This work led her to commit to formal doctoral training in clinical psychology.

The experience of loss may relate to loss of function, physical abilities and cognitive capacity, or life itself. Dr. Marasco’s patients are often newly diagnosed with terminal illness, enduring curative or palliative cancer treatment, and often have complicated medical and mental health histories.

The vision behind Transitions Professional Center was inspired by Dr. Marasco who recognized the need to establish a stronger presence of psychology in end-of-life services.
