Dr. Demi Kourtesi

PhD, Psychological Assistant

As a postdoctoral fellow, I provide psychological services to adults and adolescents including psychotherapy and psychological assessment/testing (general diagnostic clarification, OCD, ADHD,
learning disabilities, etc). As a generalist, I work with a wide range of common mental health concerns in therapy (anxiety, depression, eating disorders, PTSD, etc), but I have special clinical interest in the following areas: 

​

  • Personality Disorders

  • Obsessive-Compulsive Disorder (OCD)
     

Types of Personality Disorders:
Personality disorders are a group of 10 mental health conditions that involve long-lasting, disruptive patterns of thinking, behavior, mood, and relating to others. People with personality disorders often don’t realize their thoughts and behaviors are problematic. However, they tend to experience high amounts of distress across various aspects of life, including work and relationships. According to the DSM-5, people with personality disorders fall into one of these 10 patterns:

  1. Antisocial personality disorder: a pattern of disregarding or violating the rights of others. A person with ASPD may not conform to social norms, may repeatedly lie or deceive others, or may act impulsively which will sometimes end result in criminal activity. Psychopathy is more severe personality disturbance that incorporates some of the features of antisocial personality while also exhibiting lack of empathy, lack of fear, callousness, superficial charm, manipulativeness, and other interpersonal/affective features. 

  2. Avoidant personality disorder: a pattern of extreme shyness, feelings of inadequacy, and extreme sensitivity to criticism. People with APD may be unwilling to get involved with people unless they are certain of being liked, be preoccupied with being criticized or rejected, or may view themselves as not being good enough or socially inept.

  3. Borderline personality disorder: a pattern of instability in personal relationships, intense emotions, poor self-image, and impulsivity. A person with borderline personality disorder may go to great lengths to avoid being abandoned, have repeated suicide attempts, display inappropriate intense anger, or have ongoing feelings of emptiness.

  4. Dependent personality disorder: a pattern of needing to be taken care of, and submissive and clingy behavior. People with dependent personality disorder may have difficulty making daily decisions without reassurance from others or may feel uncomfortable or helpless when alone because of fear of inability to take care of themselves.

  5. Histrionic personality disorder: a pattern of excessive emotion and attention-seeking. People with histrionic personality disorder may be uncomfortable when they are not the center of attention, may use physical appearance or material goods to draw attention to themselves, or have rapidly shifting or exaggerated emotions. 

  6. Narcissistic personality disorder: a pattern of need for admiration and lack of empathy for others. A person with narcissistic personality disorder may have a grandiose sense of self-importance, a sense of entitlement, take advantage of others or lack empathy.

  7. Obsessive-compulsive personality disorder: a pattern of preoccupation with orderliness, perfection and control. A person with obsessive-compulsive personality disorder may be overly focused on details or schedules, may work excessively, not allowing time for leisure or friends, or may be inflexible in their morality and values. (This is NOT the same as obsessive-compulsive disorder which involves repeated unwanted thoughts/images followed by repetitive behaviors)

  8. Paranoid personality disorder: a pattern of being suspicious of others and seeing them as mean or spiteful. People with paranoid personality disorder often assume people will harm, cheat, or deceive them and don’t confide in others or become close to them.

  9. Schizoid personality disorder: a pattern of being detached from social relationships and expressing little emotion. A person with schizoid personality disorder appears apathetic and typically does not seek close relationships, chooses to be alone and seems to not care about praise or criticism from others.

  10. Schizotypal personality disorder: a pattern of being very uncomfortable in close relationships, having distorted thinking that borders the line between reality and fantasy, and eccentric behavior and appearance. A person with schizotypal personality disorder may have odd beliefs or odd or peculiar behavior or speech or may have excessive social anxiety.
     

Therapeutic Approach

​

Most people come to therapy because their life is not how they wish it was. I believe there’s two basic
ingredients to making a change. Insight and action. To satisfy the first ingredient, I help people by
connecting the dots for them and helping them see patterns they could not see before. Equipped with
that knowledge, I help people take action by making behavioral suggestions that may lead to better
outcomes. Although my general approach is psychodynamic and cognitive/behavioral in nature, as
psychologists we have many tools in our toolbox. I like to tailor each patient’s treatment to what would
benefit them most based on their unique problems and preferences.

Two of my values are transparency and evidence-based practice. After meeting for a few sessions, I will
inform the client of any disorders they seem to be currently suffering from, if any, and offer my
recommendations for treatment based on evidence derived from science.

Education and Experience

I have always wanted to be a psychologist. I started my career by pursuing a Bachelor’s degree in
Psychology from CSU East Bay, and my Master’s degree in Psychology from CSU LA. I finally received my
Ph.D. in Clinical Psychology from the University of Nevada, Las Vegas, which accomplished one of my
life’s greatest goals. I loved working at Sandstone as a practicum student and so after I completed my
internship at The University Of Texas, El Paso, I returned as a postdoctoral fellow.
Over the years, I have worked in a variety of therapeutic settings where I provided mental health
services to both adults and children. I was previously employed as a behavior therapist for children with
autism, as a psychosocial rehabilitation specialist in an inpatient hospital for adults with schizophrenia
and other psychotic disorders, and as a therapist at multiple outpatient clinics and private practices.

Personal Interests 

As my head of big curly hair and strange accent may suggest, I am originally from Athens, Greece. I
moved to the United States over 10 years ago to pursue my career, but I still visit Greece often for some
great food and sunshine. However, I enjoy a multitude of hobbies in the US. I am a Mini Cooper
enthusiast, I travel often both nationally and internationally, I skateboard and snowboard, I watch and
read thrillers and sci fi, and outside of psychology, I have an interest in philosophy and astronomy, all
things the Greeks invented of course.
