    Dr. Mohammad Aklassab has always been patient, informative, and genuinely pleasant to talk to at every appointment. He took the time to explain everything clearly at every follow up appointment and made the entire process feel comfortable and stress-free.

    After 2 years, got my braces off, and I couldn’t be happier with the results. My smile looks incredible, and I’m so grateful for the care and attention I received throughout the whole journey. I highly recommend him to anyone looking for an orthodontist for this journey!

    My son started orthodontic treatment at GSO in 2023 for a complex case involving two missing teeth that had not erupted. From the moment we met Dr. Mohamad B. Alkassab in 2025, our experience became truly exceptional. He took the time to carefully guide us through every step of the process and made us feel supported and confident throughout the treatment.
    He is incredibly professional, caring, and dedicated to his patients. His attention to detail, consistent follow-up, and genuine compassion led to remarkable results in my son’s treatment. I am deeply grateful to GSO, especially to Dr. Mohammad, for the outstanding care my son received. We highly recommend him and GSO to anyone looking for excellent orthodontic care.
