Peter Hsin MD

0001-2 Dr. Peter Hsin is a board certified general psychiatrist.  He completed his medical degree at Rush Medical College and completed his General Psychiatry residency at Loyola University Medical Center.  Dr. Hsin has hospital privileges at St. Francis Hospital.  Although he is trained to treat psychiatric conditions of all ages, he generally does not treat those under 18 years of age.  He is an expert psychopharmacologist and most of his time is dedicated to doing medication management.  He treats all standard psychiatric conditions including depression, bipolar, anxiety disorders, ADHD and psychotic disorders.  While he still does some individual psychotherapy, it is on a very limited basis.   He does enjoy couple’s therapy and received training from Dr. Domeena Renshaw’s Sexual Dysfunction Clinic.  A product of island culture, his patients appreciate his laid-back demeanor.  He is generally on schedule (within 5 minutes) and is especially good for a physician.  He does not use an answering service and patients contact him directly on his cell phone.
Have you tried multiple medications and found them intolerable or ineffective?  Dr. Hsin offers pharmacogenomic testing.  The test is safe and sequences for your exact genotype for various liver enzymes and markers for serotonin and other neurotransmitter systems.  It predicts which medications needs to be specially dosed for you and if certain neurotransmitter systems are more or less likely to work for you.  If you have failed 2 or more psychotropic medications, you should be considered for pharmacogenetic testing.  The days of pure guesswork are over.

Martin McCarthy PhD

All of us — women and men, young and old, poor, middle-class, and upscale folks, minorities and majorities, of whatever kind — face challenges and unremitting complexity in our confusing and frequently unpredictable post-modern world.

Our ability to manage our emotions and improve our relationships can be limited by our prior histories and our present circumstances. That said, positive changes are possible for everyone, and most of my patients experience significant reductions in their symptoms and see long-term improvements in their quality of life.

My psychotherapy practice includes a diverse group of people who are working to heal the hurts of the past, deal with present challenges, and plan for and achieve a better future. I use an array of effective psychological treatments and other evidence-based approaches to help people live happier and more fulfilling lives.

  • Cognitive behavioral therapy and dialectical therapy can help patients better manage stress and deal with depression, anxiety, social anxiety, irritability and anger, OCD-OCPD, ADHD, grief, aging-related, and medical problems.
  • I encourage and teach clients how to use mindfulness, meditation, acceptance therapy, and positive psychology concepts to produce notable benefits in their day-to day lives.
  • Best practices from executive coaching have proven helpful to many patients who are dealing with academic problems and to other clients who are coping with employment and workplace issue
  • I use family systems concepts, couples therapy methods, and sex therapy techniques to reformat and restructure interpersonal relationships; I also use findings from research on social networks to improve client’s health, mental health, and social interactions.

My original training and my earlier professional experience was as a research psychologist. I worked in community mental health settings and in academic medical centers and conducted research on factors that improved treatment outcomes and maintained patient’s health and mental health status. Along with others in my research network I have published frequently cited articles in high impact journals such as JAMA, Medical Care, the Journal of the American College of Surgeons, the Journal of the American Geriatrics Society, and Psychopharmacology.

Throughout my career I have made a point of increasing my clinical knowledge and deepening my treatment skills. I received an M.A. in Experimental Psychology from Columbia University and I completed a Ph.D. in Community Psychology at New York University, followed by a Post-Doctoral Fellowship in Health Psychology at Northwestern University Medical School. In addition to seminars and practicums in Clinical Psychology during my graduate studies, I have post-graduate training in cognitive behavioral therapy at the New York State Psychiatric Institute, and in family therapy at New York University Medical Center, and at The Family Institute of Chicago.

I am part of a caring and effective clinical practice and high-quality medication management and referrals to other providers are available within our group. Being an excellent therapist has been my main focus since retiring from Northwestern University Medical School and beginning work in a private practice setting. I look forward to helping you move forward happily and productively on your journey.
