Our Team //

The Chicago Center for Cognitive Wellness (CCCW) specializes in helping people who are experiencing brain changes and their families.  We do this through detailed cognitive assessments when needed and through a variety of treatment services that include group and individual cognitive rehabilitation and psychotherapy.  


Given our unique focus, each CCCW provider is hand selected, trained and supervised by Dr. Sherrie All, founder and owner of the practice. Trained as a neuropsychologist, Dr. All founded CCCW in 2012 to provide the “what’s next” to people following a diagnosis of memory loss or other changes in other thinking skills such as attention or executive function.  Dr. All was and is passionate about filling a much-needed treatment gap for these people as they work to improve their lives in the face of difficult circumstances. As Dr. All’s success in treating these unique patients and families has grown, so has her team.


Working together to meet the enormous needs of this broad population, our team of providers brings a detailed understanding of the brain to uniquely address the needs of people affected by concussion, traumatic brain injury (TBI), stroke, early-stage dementia, mild cognitive impairment (MCI), attention deficit / hyperactivity disorder (ADHD), brain surgery, multiple sclerosis (MS) and other related brain declines. Our providers have a keen interest in working with family, often working individually with care partners, who themselves experience high rates of stress and stress-related disease.

Under the direction of Dr. All, each provider works from an integrative approach to deliver the highest quality, cutting-edge interventions. Services are tailored to the unique needs of each patient, pulling from a dense toolbox of evidence-based cognitive rehabilitation and psychotherapy interventions.

Sherrie All, Ph.D. | Licenced Clinical Psychologist


Founder, Owner & Director


Dr. Sherrie All built the practice out of a passion for teaching people about the brain that influences her approach to training, speaking, writing, and consulting. Dr. All hand-selects each provider for the practice and meets with her team regularly for supervision and training to ensure that each provider is equipped with the most up-to-date and effective interventions for treating this specialized population. Dr. All is also an engaging speaker, consultant, and writer on topics of positive neuropsychology and brain health. Her keynote address “Building your Brain’s 401(k)” offers an entertaining way of promoting popular understanding of the scientific theory of cognitive reserve to teach people how to care for their brains.

In addition to running her practice, Dr. All trains other providers on how to implement cognitive rehabilitation interventions into their practice, through CEU programs and individual consultations.  She is also a leader in the field of brain health working to educate the public on brain-healthy behaviors, earning the attention of media outlets such as The New Yorker and Crain's Chicago Business


Dr. All received her Ph.D. in clinical psychology with a specialization in neuropsychology from Rosalind Franklin University of Medicine & Science in North Chicago, IL. She completed her pre-doctoral internship and 2-year post-doctoral fellowship at Rutgers Biomedical & Health Sciences, where she honed her skills in cognitive rehabilitation, psychotherapy, and neuropsychology. Her research has focused on understanding and improving cognition in people with serious mental illness and lowering the risk of age-related cognitive decline.


Steven Bernfeld Ph.D. | Licenced Clinical Psychologist

Dr. Steven Bernfeld specializes in caring for patients with cognitive decline and their family members and serves as a clinical supervisor in the practice. Dr. Bernfeld enjoys working with people struggling with changes associated with concussion, brain-injury, medical conditions and dementia as well as individuals experiencing anxiety, depression, caregiver stress, grief, and other mood disturbances. Drawing from his considerable experience in providing cognitive behavioral therapy (CBT) to adults of all ages, Dr. Bernfeld’s approach involves helping people learn about the function of their brains and the relationship between their thoughts, feelings, and behaviors. While Dr. Bernfeld uses evidence-based treatments to enhance treatment outcomes, he also believes that the most effective interventions are built on trusting relationships wherein people harness the motivation needed to recover by gaining a better understanding of themselves.


Dr. Bernfeld received his Ph.D. in counseling psychology from the University of Wisconsin – Milwaukee. He completed his pre-doctoral internship at the William S. Middleton VA Hospital in Madison, WI, and a 2-year post-doctoral fellowship at Rush University Medical Center in Chicago, IL, focusing on work with older adults. He has also received specialized training in cognition and functional neuroanatomy. His research has focused on interventions for people with dementia and their family caregivers as well as psychotherapy effectiveness and access to healthcare for older adult, diverse and underserved populations.
