Internal Medicine & Pediatrics of Tampa Bay

We provide the highest quality of medical care to the families of Westchase and the surrounding communities in the Tampa Bay area.


Dr. Mark Bilella and Dr. Frank Demery started Internal Medicine & Pediatrics with the goal of providing high quality health care to the families in the local community. Both Dr. Bilella and Dr. Demery are dual board-certified in pediatrics and internal medicine. This unique training allowed them to care for newborns and parents as well. This approach has allowed them to build a strong bond with all members of the family and provide a higher level of care. Another goal was to create an office that feels like a home, in order to provide a level of comfort for our patients. We have several waiting rooms separated for adults, children, and newborns. Our friendly staff and therapy dogs work hard to put people at ease at the office visit to make it a more enjoyable experience. It has been our pleasure to build bonds and relationships with members of the local community for over a decade.

As the practice has grown over the years, we have expanded to a multispecialty group, but continue to provide care for patients of all ages. We have added one additional pediatrician, Dr. Karen Ackley, as well as two Family Practice Nurse Practitioner, Tera Ritchie and Kristen Gross. We strive to provide convenience with in house lab draws, on line communication with the Patient Portal, and electronic prescriptions. We take time to educate our patients and involve them in the health care process. We take great pride in providing a superior experience that can best be achieved with a smaller independent medical practice. We will continue to do our best to improve, so we can meet the needs of our patients. We look forward to watch our families grow and help them maintain good health in years to come.
