Who We Are

We are a private group practice of board-certified psychiatrists who are on the faculty of the Feinberg School of Medicine at Northwestern University. Our practice is located in downtown Chicago.

We focus on the care of recurrent mood conditions, obsessive compulsive disorders, and ADHD. Our treatments utilize psychopharmacology, a variety of psychological therapies, chronotherapeutic practices and other modalities. We have each received extensive training in psychodynamic psychotherapy. Unlike many psychiatric groups where psychiatrists only prescribe medication, we are committed to providing both biological and psychological treatments together.

Dr. John Gottlieb

Dr. John GottliebMoods have always fascinated me. This interest, along with a love for talking to others, led me towards my first psychology course in college. From that point on, I knew what I wanted to do. After graduating from Oberlin College in Ohio, I attended medical school at the University of Illinois at Chicago, and then completed my residency in psychiatry at Yale University in New Haven, CT. I returned to Chicago, obtained my board certification in psychiatry and started a solo outpatient practice.

In my first years in practice, I was committed to being the best generalist that I could be. I wanted to see and learn how to treat as many conditions as possible. I increased my skills in psychopharmacology, psychodynamic and psychoanalytic psychotherapy, and cognitive behavioral therapy. Initially, this generalist orientation was very satisfying. I enjoyed being a jack-of-all trades and having a practice with a broad scope. Over a decade, this began to change.

First, I began to see more and more patients with mood problems, especially bipolar disorders. The natural skills and competence that I had in this area was strengthened by this growing clinical experience. Second, I found it increasingly hard to stay current with new psychiatric research developments across our field. There was simply too much to know, too much to learn, and not enough time to do it. Third, the more I treated those struggling with recurrent mood problems, the more I enjoyed it. It's fascinating, challenging work. It's also an area where I've consistently seen treatment make a difference in people's lives. The net effect of these factors encouraged me to make mood disorders the central part of my practice.

Over the past ten years, I have focused my attention on understanding and treating recurrent emotional conditions. Through professional talks I give, literature reviews, systematic study of affect and affective regulation, case conferences, research we conduct, professional conferences, courses I teach, and my work on the education committee of the International Society of Bipolar Disorders – my knowledge in this area has deepened and sharpened. While my diagnostic focus has narrowed primarily to mood disorders, my earlier generalist orientation remains as a commitment to providing care that is comprehensive. So while I predominantly treat those with mood problems, I am mindful of, and try to address the full range of biological, psychological, social and educational needs of my patients; Comprehensive care for a select group of problems.

Dr. Susan Stern

Dr. Brett PlylerI have always been fascinated by the workings of the human mind. Prior to going into psychiatry, I studied English at Yale University, where I became attuned to the mood fluctuations of generations of great authors. While I considered graduate study in English, my interest in medicine prevailed, and I entered Weill Cornell Medical College eager to learn how to treat patients with similar disorders. Psychiatry for me represented the perfect synthesis of medical science and a humanistic approach to the entire patient. After medical school, I entered my residency at Columbia, from which I graduated in 2002.

Since medical school and residency, I have been committed to patient care at the highest level. I have worked with a wide range of patients in private practice, community mental health and outpatient clinic settings. I am board-certified in Adult Psychiatry by the American Board of Psychiatry and Neurology. Also since 2002, I have been involved in the teaching of medical students, psychiatry residents, psychology interns, social workers, nurse practitioners and physician assistants. From 2002 to 2006 this teaching was done at Columbia, where I was a Clinical Instructor of Psychiatry and an Attending Psychiatrist at the Outpatient Psychiatry Clinic. My focus during this time was teaching trainees about psychiatric evaluations and psychopharmacology. I also maintained a thriving private practice in Manhattan and Westchester County.

In the summer of 2006, I left the New York area, where I had lived for the previous 12 years, and moved to Fairfield, Iowa in order to support my husband, who was expanding a business there. This turned out to be an opportunity for personal and professional growth. From 2007-2011, I served as a Chief Medical Officer at Life Solutions Behavioral Health in southeastern Iowa. I had extensive clinical and supervisory duties in the position, offering support, guidance and clinical information to patients and staff. I was struck by the broad range of patients that I treated during this time period. It was a valuable clinical experience that very much added to what I had learned previously. Ultimately, though, we decided to relocate to Chicago. My search for a practice opportunity there led me to Drs. John Gottlieb and Brett Plyler of Chicago Psychiatry Associates, with whom I have discovered common ground with our mutual interests in mood disorders, psychotherapy, teaching, and keeping up with the latest developments within the field of psychiatry.

While I have had experience in a broad range of psychiatric illnesses, I am particularly intrigued by mood disorders, especially bipolar disorder. I have had the opportunity to receive mentorship and training in this area, both during and after residency. I have come to understand that bipolar disorder is not a single illness, but that it occurs along a continuum. This can present difficulties in making a proper diagnosis and implementing appropriate treatment, and much of my consultation work has been in clarifying for patients what their diagnosis is – whether it be depression, anxiety, bipolar disorder and/or ADHD (Attention Deficit Hyperactivity Disorder)—all of which can present with similar symptoms. I have a particular interest in mood disorders in women, which are complicated by significant hormonal fluctuations within the female life cycle.

After a thorough evaluation process, I select treatment based on both pharmacological and psychological approaches. I have utilized a broad range of therapeutic modalities, including insight-oriented, supportive and cognitive-behavioral therapy (CBT). I truly believe that success in treatment results from an understanding of the underlying illness in the context of family and interpersonal relationships. My work with patients is collaborative with the goal of maximizing each person's strengths, leading to functioning at his or her full potential. Download my Curriculum Vitae in PDF format.

Dr. Megan Pirigyi

Dr. Megan PirigyiI have always had a strong interest in the mind, but my path to psychiatry was somewhat circuitous. After completing my undergraduate degree at Amherst College in Philosophy and Fine Arts, I initially accepted a fellowship to pursue a doctoral degree in philosophy, as I loved teaching and writing, and was particularly drawn to questions about consciousness, the mind, and personal identity. While I enjoyed this work, I ultimately left graduate school to study medicine, as I wanted a career in which I could have a more direct and substantive impact on others.

Following completion of premedical coursework at Tufts University, I moved to Chicago to attend medical school at Northwestern. While I had many clinical interests, I was most intrigued by psychiatry. I enjoyed learning about my patients and their individual experiences, and I valued psychiatry’s focus on improving quality of life. Additionally, I was attracted to the intellectual challenge and nuanced problem solving inherent to the field, and was fascinated to learn about the biological underpinnings of the mind and behavior.

Seeking strong and well-balanced training in both biological psychiatry and psychotherapy, I chose to stay at Northwestern for my psychiatry residency. During training, I treated a wide variety of complex conditions in the inpatient and outpatient settings, and pursued elective experiences in women’s mental health, addiction medicine, and sleep medicine. I also had instruction and supervision in a range of psychotherapies including psychodynamic, supportive, interpersonal, cognitive behavioral, and family and couples therapy. I currently have a particularly strong interest in the treatment of mood disorders including depressive and bipolar disorders. Additionally, I enjoy treating anxiety disorders, obsessive-compulsive disorder, trauma and stress-related disorders, and ADHD. In my clinical approach, I work with patients to develop a shared understanding of their unique experiences of symptoms, their particular strengths, and the various contributing factors underlying and influencing their symptoms. I then use this insight to build a personalized treatment plan, with the objective of maximizing each patient’s functioning so that he or she can pursue fulfilling and meaningful goals.

Dr. Kurt Kastenholz

Dr. Kurt KastenholzI have had a lifelong interest in the human mind. As an undergraduate at the University of Wisconsin-Madison, I studied psychology and history, curious about both the workings of the human mind and patterns in the ways humans have interacted throughout time. I considered graduate study in psychology, but chose to enroll at the University of Wisconsin School of Medicine and Public Health so as to learn how to evaluate and treat patients in a comprehensive manner reflecting both psychology and the physiology of the entire human body. In medical school, I found that the field of psychiatry offered me the opportunity to engage in this sort of comprehensive evaluation, and the chance to make a significant impact on the patient’s overall quality of life.

Following completion of medical school, I pursued residency training in psychiatry at Northwestern University. I was attracted to Northwestern in particular due to the strength of its training in a variety of psychotherapy modalities, in addition to a strong grounding in medical science. During training, I gained experience treating a broad variety of mental health problems in multiple settings, both inpatient and outpatient. I have been trained in numerous psychotherapy modalities including supportive, cognitive-behavioral, interpersonal, psychodynamic and family and couples therapy. I additionally pursued elective experiences in intensive addiction treatment as well as sleep medicine.

Clinically, I am greatly interested in mood disorders, both depressive and bipolar disorders. Other areas of particular interest to me include obsessive-compulsive disorder, generalized anxiety disorder, and social anxiety disorder. During evaluation and treatment, my focus is on developing an understanding of the patient’s symptoms throughout their lifetime, and the meaning and importance of those symptoms to the patient. This requires an integration of many different aspects of the patient’s life history, including relationships, cultural background, education and vocation, trauma, sexuality, and gender, among others. I work collaboratively with each patient to create a mutually agreed-upon treatment plan based on our shared understanding of the problem areas and therapy options. This collaboration fosters engagement, strengthens our alliance, and supports a comprehensive approach to the treatment.

Dr. Mark Chapman

Dr. Mark Chapman I attended psychiatry residency training at Northwestern University in Chicago, IL, where I also completed a forensic psychiatry fellowship. After my fellowship, I joined the faculty and medical staff at Northwestern. In addition to teaching and supervising medical students and residents, I provided care to a diverse set of individuals with disorders related to mood, trauma, anxiety, attention and psychosis. I also performed forensic psychiatric evaluations related to issues of disability, workers’ compensation, competency, fitness for duty, and the insanity defense. While I greatly enjoyed my work at Northwestern, I desired to focus more on direct patient care, which led me to join Chicago Psychiatry Associates.

My current practice includes the treatment of individuals with a variety of clinical concerns with a specialized focus on mood and attentional disorders. I value a thorough diagnostic assessment in order to provide individualized care. Because I am skilled in utilizing biological treatments, such as psychiatric medication, as well as psychotherapy, I can provide my patients with multiple treatment options. I emphasize a thorough discussion of my diagnostic impressions, and I strongly encourage patients to ask questions and share in treatment decisions. My goal is for patients to feel comfortable and confident about their care.

In addition to treatment, I am also available for forensic psychiatric evaluations and consultations in both civil and criminal matters.

Dr. Indrany Datta-Barua

Dr. Indrany Datta-BaruaAs a longtime student of both the arts and science, the interaction of culture and biology has long been an undercurrent of my interests. I initially struggled with how to merge the two until I found Psychiatry.

After earning an engineering degree in Computer Science at Princeton University, I accepted a fellowship to study literature and culture in Japan. Though an invaluable experience, my studies there lacked a direct personal and practical connection with a wider community. I therefore returned to the United States to complete pre-medical coursework at Columbia University in New York.

While in medical school at Case Western Reserve University, I enjoyed the puzzles and ambiguity inherent in psychiatry. At the same time, I was most moved by the shared philosophies of psychiatry and palliative medicine, which both emphasize quality of life, meaning in the face of a life-changing diagnosis, and attention to the multidimensional aspects of an individual’s identity within a social context.

During my residency at Tufts Medical Center in Boston, I received a strong biological education in psychiatry under supervisors like Dr. Nassir Ghaemi, preeminent author and expert in manic-depressive illness, and through my participation in the care of severely ill patients of all ages, ethnicities, and socioeconomic backgrounds. In the heart of Boston’s Chinatown, I particularly enjoyed unique exposure to the presentations of mood disorders in individuals of Asian descent.

In addition to Tufts’ standard curriculum in psychotherapeutic training, including supportive, psychodynamic, cognitive behavioral, dialectical behavioral, and couples therapy, I chose to deepen my psychotherapeutic training by concurrently enrolling in the one-year Psychodynamic Psychotherapy Fellowship at the Boston Psychoanalytic Society and Institute.

I then pursued a fellowship in Hospice and Palliative Medicine at Northwestern in order to explore how to apply the concepts I had learned in psychiatry to the care of individuals and families coping with serious illness. Through the course of that fellowship, I was struck by the unique challenges of treating and coping with life-limiting medical illness for those with a history of episodic mood disorders, as well as the challenge of accurately diagnosing and treating a mood episode concurrently with a serious physical illness.

Additionally, I am deeply interested in the existential and psychodynamic concerns that arise in the context of a life-limiting illness, their effects on mood and relationships, and how to facilitate coping and psychological development in order to improve quality of life and, in appropriate cases, allow for a good death.

I believe that combined biological and psychological therapies produce the best outcomes, as we navigate living with the biology with which we were born in the social context in which we live, work, and love.
