Alexander Van-Den-Ende, DO

Dr. Caitlin Tillberg (she/her) is a board-certified psychiatrist. She has a BA in musicology and cognitive science from Oberlin College, an MD from Quinnipiac University in Connecticut, and completed general adult psychiatry residency at Duke University. Dr. Tillberg practices patient-centered and trauma-informed care, valuing patient autonomy and collaborative decision-making, acknowledging the burden many people carry from intersecting oppressions. She believes therapy is important � often equally important as medication, or more � and will work together with you to make a realistic treatment plan that will fit into your life. Dr. Tillberg also has a niche working with people with complicated relationships with their bodies, whether due to disordered eating, gender dysphoria, chronic illness/disability, or trauma. She welcomes LGBTQ+ patients, including trans and non-binary adults. She also enjoys working with patients with OCD, as well as autistic/neurodivergent adults (including those seeking adult autism evaluation). Please note Talkiatry is most appropriate for autistic patients with Level 1 (or case-by-case Level 2) support needs and who are verbal. Regarding eating disorders: Please note that for patient safety, per Talkiatry policy, Dr. Tillberg is unable to work with patients with current active anorexia nervosa or bulimia nervosa (or significant relapse in the last 6 months), or with patients requiring current regular medical or lab monitoring for complications of binge-eating disorder or ARFID. Bariatric surgery patients are welcome if medically stable. Patients with current disordered eating that does not rise to the level of a formal diagnosis of anorexia or bulimia, or with a past history of anorexia or bulimia in sustained remission, will be evaluated on a case-by-case basis at the first appointment. Dr. Tillberg looks forward to meeting you.
