Semirosas stands for student growth and success! We:

  • Provide educational services, such as academic and language tutoring. Online sessions are available.

  • Create educational resources, such as student websites, booklists and how-to checklists to address academic skills.

  • Design consulting services, including working with organizations to establish or improve learning programs and developing learning products to facilitate student achievement. We train faculty, advise administrators, facilitate workshop series, and design and create PowerPoint presentations.


No team is complete without the meaningful engagement of clients, professionals, and family members. Angela Y. León founded Semirosas after years of research and working closely with clients, speech-language therapists, occupational therapists, physical therapists, psychologists, teachers, classroom support professionals and families, mainly in New York City. Out of these experiences arose the conviction that independent students plus fully-engaged support systems equals positive results. Semirosas invites you on this journey of growth and success!
