Cherie L. Massmann, MA, LPC, NCC

Working together as colleagues, we realized we had a shared passion for learning and providing quality, evidence-based treatment for eating disorders including CBT, DBT and FBT.  

We founded Partner in Wellness in St. Louis based on our shared values of family (yours and ours), balance, quality of life and adventure. We strive to be a resource for the community through education, creativity, and quality care.  An eating disorder can be a barrier that stands between a person and the life they truly desire. We are passionately committed to treating the disorder and removing the barriers so our clients can pursue their passions. 

Cherie Massmann is a cognitive-behaviorally trained therapist with over 15 years of experience treating binge eating disorder, anorexia nervosa, bulimia, depression and anxiety in adults and adolescents.  She also holds certification for family based treatment.

Cherie is a founding partner in Partners in Wellness, which specializes in evidence-based treatment approaches to eating disorders, depression and anxiety disorders.

Prior to starting Partners in Wellness, Cherie served as staff therapist for Webster Wellness Professionals/McCallum Place. She led the Greenlight Weight Management Program, helping individuals achieve long-term healthy weight loss. Additionally, as a certified Family Based therapist, Cherie guided patients and their families towards recovery from anorexia and bulimia.

Prior to joining Webster Wellness, Cherie was a staff therapist at Washington University School of Medicine, working in the Psychiatry and Internal Medicine Departments. She played a key role in several National Institute of Health (NIH) studies, serving as designated clinician on the following:

  • Treatment Options for Type 2 Diabetes in Adolescents and Youth (TODAY study)
  • Comprehensive Maintenance Program to Achieve Sustained Success (COMPASS), a treatment of childhood obesity
  • Comprehensive Assessment of Long-Term Effects of Reducing Intake of Energy (CALERIE study). In addition, she worked with patients diagnosed with Type II and gestational diabetes.

Cherie is a Licensed Professional Counselor (LPC) and National Certified Counselor (NCC). She earned her master's degree in counseling from Webster University, and she holds bachelor's degree in psychology from Missouri State University. She is passionate about helping her clients improve their overall quality of life.

Dr. Kirsten Gilbert holds a bachelors degree from Stanford University, her doctorate in Clinical Psychology from Yale University, and an APA accredited predoctoral internship from Northwestern University Feinberg School of Medicine. She is a licensed clinical psychologist with training in evidenced-based treatments, specializing in radically open dialectical behavior therapy (RO-DBT). She also has training in dialectical behavior therapy (DBT) and cognitive behavior therapy (CBT). 

From an RO-DBT framework, Dr. Gilbert works with patients suffering from over-controlled behavior, including rigid responses, inhibited emotional expression, strong need for structure, social isolation or distant social relationships, and/or perfectionism. RO-DBT helps individuals relax rigid and inflexible control and increases social connections, intervening on underlying causes of the individuals suffering, rather than targeting symptoms of the disorder. Using this model, Dr. Gilbert works with patients with treatment-resistant anxiety, anorexia nervosa, depression and related conditions of over-control.

Dr. Gilbert has previously completed postdoctoral fellowships at Northwestern University and Washington University in St. Louis School of Medicine.
