About Us    

  Shortly after graduation in 1980, Dr. Frazer founded his practice specializing in anxiety disorders – panic disorders with agoraphobia, in particular. The practice quickly grew to a complement of several trained professionals. In addition to receiving numerous referrals from local family physicians and psychiatrists, the practice has received thousands of referrals through word of mouth as result of the excellent service provided to residents of the Durham, Markham, and Scarborough communities for the past 34 years. Over that time, Dr. Frazer and Consultants have conducted more than 300,000 interviews/sessions and have assisted many individuals, couples, and families with a variety of psychological difficulties. They have provided support to police officers and civilians from the Durham Regional and Toronto Police services, the Ontario Provincial Police (OPP), and the Canadian Security Intelligence Service (CSIS). This practice had an exclusive contract with salaried personnel from General Motors of Canada, and we assisted our clients to cope with job stress, loss and grief due to plant closures, and concerns related to changes in the workforce. Dr. Frazer’s practice has also completed assessments for the Workplace Safety and Insurance Board (WSIB), as well as Independent Psychological Evaluations (IE’s) for the insurance industry for those suffering from disability resulting from motor vehicle or workplace accidents.

Dr. Frazer is a registered psychologist who has seen children, adolescents, and adults for individual, couples, and family therapy. He enjoys seeing children with anxiety disorders, behavioral difficulties, and Attention-Deficit/Hyperactivity Disorder (ADHD). Adolescents have received support for anxiety, depression, relationships, family conflict, academic, and peer-related difficulties. For more than 30 years, Dr. Frazer has treated adults suffering from panic attacks, social phobia, obsessive compulsive disorder, generalized anxiety disorder or excess worry, agoraphobia, specific phobias, depression, bipolar illness, adult ADHD, posttraumatic stress disorder, pain disorders, trauma and loss caused by motor vehicle accidents, personality disorders including borderline personality disorder, grief-related to thedeath/loss of loved ones or marital separations, and has extensive experience conducting marital therapy. Dr. Frazer has also seen children and adults for sports performance enhancement.

Dr. Frazer has trained psychologists under supervised practice and enjoys supervising staff. Since 1980, he has utilized a cognitive behavioral orientation combined with a psychodynamic approach. He holds a strong belief that attachment and early learning lead to experiences which relate to one’s current problems, and often contribute to anxiety disorders, depression, and relationship difficulties. He also uses metacognitive therapy techniques to further enhance treatment. Dr. Frazer encourages collaboration with family physicians and psychiatrists because of the occasional requirement for medication, which is often a useful adjunct to successful treatment.

  Dr. Frazer completed his M.Sc. and Ph.D. in Clinical Psychology with an emphasis on Neuropsychology at the University of Victoria. Prior to that, Dr. Frazer received a B.Sc. in psychology from Queen's University.

Dr. Frazer has been trained in both assessment and treatment for psychological and behavioural issues, as well as neuropsychological (brain-based) deficits, disorders, and injuries. He has been active in this practice for the past 3 years. Dr. Frazer is competent to provide psychotherapeutic intervention for a variety of psychological issues in adults, including but not limited to anxiety, mood disorders, chronic pain, eating disorders, relationship issues, adjustment issues, grief, as well as personality disorders. Dr. Frazer primarily utilizes cognitive-behavioural and interpersonal approaches to treatment, but has also been trained to implement a variety of empirically-supported techniques from diverse theoretical orientations depending on client needs.

Through Dr. Frazer’s specialized training in the field of neuropsychology, he is competent in the areas of assessment, diagnosis, and management of a multitude of neurological and neuropsychological deficits and difficulties; specifically focusing on the relationship between underlying brain functioning and/or pathology, and resulting cognitive and behavioural outcomes. Changes in brain functioning may be due to a number of causes (e.g., genetics, developmental issues, neurological changes, physical injury), and reasons for referral for a neuropsychological evaluation might include, for example: traumatic brain injury, cerebrovascular disease (e-g-, stroke), brain turners, mild cognitive impairment, dementia, multifocal CNS disorders (e.g., Multiple Sclerosis), movement disorders (e.g., Parkinson's Disease), Epilepsy, brain infection (e-g., meningitis), developmental disorders (e.g., ADHD, PAM), Learning Disorders), and sports-related injury (e.g., concussions). Typically, referral questions involve return to work decisions, potential for cognitive recovery, behavioural management strategies, driving safety, cognitive competency to manage important activities of daily living, recommendations regarding cognitive rehabilitation, and compensation for functional deficits (including school- or work-based interventions).

Dr. Frazer is currently competent to conduct neuropsychological assessments for individuals who are 16 years of age and older. A neuropsychological assessment involves a thorough evaluation of brain functioning, and the provision of appropriate recommendations based on the referral question, the client's presenting concerns, their specific life circumstances, and empirical research. Brain functioning is determined by underlying brain structures and systems, and is assessed objectively using standardized tests and qualitatively on the basis of clinical judgment, knowledge and experience. Domains assessed include general intellectual ability, academic skills and knowledge, attention, motivation, visuospatial abilities, memory, executive functions, language, motor skills, mood, and personality.
