About Us
Rosario Therapy Center is located in the heart of the Kaiserslautern Military Community (KMC) in Ramstein-Miesenbach, Germany. We serve American military and expatriate families with an array of needs from infancy to adults. We are dedicated to providing a premium service for families that may be otherwise inaccessible.
We care deeply for our children/families and their progress throughout the time that they are with us and beyond. Here at RTC we strive for consistency and continuity of services. However, just as clients relocate, clinicians relocate every so often as well. In this transient community it is ideal to strive for consistency and continuity of clinical services provided for your child. In order to ensure this, we have taken up a group practice model. In the event that a clinician is unavailable for your scheduling needs, we will transition your child to another clinician as seamlessly as possible to ensure that services are maintained. Maintenance, consistency, and follow-through, both in and outside of the clinical setting, are powerful tools in ensuring therapeutic success for your child. We strive to provide a gold standard in American-trained, German-based services with the expectation of quality that you have come to know and trust.

Her love of the medical field and servicing populations in need led her to develop her career as a Speech and Language Pathologist. Prior to finding a love and passion in aiding children with speech and language disorders she was a trial discharge case worker in N.Y.C. She advocated for and facilitated the safety and wellness of New York’s vulnerable and marginalized children exiting the foster and congregate care systems. Shifting into the medical social-welfare field of speech, language and hearing sciences, she was able to implement her learned skills seamlessly in the military and expatriate community by providing a gold standard, evidence-based service for infants and children in need for the last 7 years.
When Sultana is not glued to her computer, conducting therapy, being super mom, or carrying out the many tasks needed for her clinic, she is giving back to the professional community by serving on the board for the Overseas Association of Communication Sciences (OSACS), ensuring that opportunities for continuing education abroad are accessible. Sultana also maintains and advocates for cultural awareness and diversity in the community by supporting the Kaiserslautern Military Community Caribbean Heritage Association in their volunteer efforts and local events.

She is a veteran skater and Training Chair for Kaiserslautern Roller Derby, a traveling international sports team connecting people from all walks of life in an inclusive, active, and fun atmosphere.
Thomas Kinkade said, “Balance, peace, and joy are the fruit of a successful life. It starts with recognizing your talents and finding ways to serve others by using them.” Sultana embodies this message as she continues to apply her acquired knowledge in servicing her community across all facets of need and engagement.
