Adolescent-Young Adult Medicine

What Adolescent-Young Adult Medicine does

Adolescent-Young Adult Medicine (AYAM) is a private medical practice founded in 1990 by Dr. Andrea Marks in New York City, focused exclusively on the 9–30 age range. The practice provides comprehensive primary care (acute illness, chronic illness management, annual check-ups, immunizations, nutritional guidance, hospitalization supervision) alongside specialized services in eating disorders, LGBTQ+ health, reproductive health and gynecology, male health, developmental and emotional difficulties, substance use, overweight/obesity, travel health, and undiagnosed conditions. Care is delivered via in-person visits at a single Manhattan office (1050 Fifth Avenue, Suite 2), supplemented by telemedicine/virtual visits, with same-day sick visits and 24/7 physician on-call access. A collaborative care model coordinates treatment with psychiatrists, psychologists, therapists, social workers, nutritionists, and educational professionals.

The underlying technology is conventional medical-practice infrastructure: a telemedicine platform for virtual consultations, in-office rapid diagnostic testing (strep, flu, mono, UTI, yeast), and full immunization services including travel vaccines. There is no proprietary software product, AI component, or data platform described. Two board-certified adolescent medicine physicians — Dr. Karen Rosewater (joined 2000) and Dr. Doris Pastore (joined 2007) — anchor the clinical team, with attending affiliations at Mount Sinai Hospital and the Icahn School of Medicine.

AYAM operates as an out-of-network provider on a time-based fee-for-service model. Patients pay at the time of visit and receive superbill receipts for insurance reimbursement. Fees scale with visit duration: new-patient visits range from $720 (30 minutes) to $1,360 (120 minutes), follow-up visits from $230 to $910, annual/pre-college visits from $535 to $915, consultations from $545 to $970, with an additional $175 charge for weekend/after-hours visits. The practice distributes updated fee schedules periodically, with the latest revision effective October 1, 2025. Go-to-market is entirely direct-to-consumer via referrals, word-of-mouth, and self-referral, supported by a content-rich website.

Regional players

• NewYork-Presbyterian — Komansky Children's Hospital: Major NYC academic medical center with pediatric and adolescent medicine services. Operates in the same Manhattan market as AYAM, providing an in-network alternative for families seeking adolescent-focused care.
• NYU Langone — Hassenfeld Children's Hospital Adolescent Medicine: NYC-based academic children's hospital offering adolescent primary and specialty care. Direct geographic overlap with AYAM in Manhattan, competing for similar patient demographics though operating within a larger hospital system.

Broad incumbents

• Children's National Hospital — Adolescent Medicine: Major pediatric hospital with adolescent medicine subspecialists and an eating disorders program. Comparable in clinical scope and subspecialty training pipelines; serves DC-region patients rather than NYC.
• Seattle Children's Hospital — Adolescent Medicine: Regional pediatric academic center with a fellowship-trained adolescent medicine division comparable in clinical scope. Operates on the West Coast with no NYC overlap.
• Mount Sinai Adolescent Health Center: Hospital-based adolescent medicine program affiliated with the same Mount Sinai system AYAM partners with; offers comprehensive care to adolescents and young adults in NYC, including primary care, mental health, and reproductive health. Comparable in patient population and service mix but operates as a hospital outpatient department rather than a private practice.
• Children's Hospital of Philadelphia (CHOP) — Adolescent Medicine: One of the largest pediatric academic centers in the US with a dedicated adolescent medicine program. Comparable in clinical focus (eating disorders, LGBTQ+ care, reproductive health) but serves a broader pediatric population across a hospital network.
• Boston Children's Hospital — Adolescent Medicine: Academic pediatric hospital with a fellowship-trained adolescent medicine division (where Dr. Rosewater trained). Comparable subspecialty depth in eating disorders and adolescent reproductive health, though delivered in a hospital rather than private-practice setting.

Emerging players

• Cincinnati Children's Hospital — Eating Disorders Program: National referral center for pediatric and adolescent eating disorders. Comparable in eating-disorder specialization but operates as a research-driven hospital program rather than a private outpatient practice.
