    About Us

    The Practice

    The Bay Medical Center strives to create a atmosphere of safety and trust for our patients.  

    Our doors opened in 2001 and continues to provide individualized health care to our patients.

    The Bay Medical Center is one of the last SOLO practices left in the area.  Theree are no nurse practitioners nor physician aids you see the Doctor at every visit.  

    Dr. Ostrzenska (Dr. Kasia)  is a passionate educator.  She spends much of the visit time  educating her patients so they become well versed in the details of their treatment plans.  We believe that knowledge  is the key to your success and compliance.  

    Dr. Kasia travels all over the world to keep on top of the most recent research which she implements into her treatments.   Her patients get as much time as they need and you will almost never wait for your appointment :-).  Patients have 24/7 access to Dr. Kasia by phone or computer portal in case of emergencies.  

    Dr. Kasia no longer attends hospitals and the practice does not accept any medical insurances.
