Dr. Andreas Bollmann is a board-certified pediatrician, an advisory board member of the College of Physicians of Philadelphia, a member and fellow of the American Academy of Pediatrics (FAAP). He's been a published author of peer-reviewed medical journal articles, a researcher and a medical educator. The greatest joy of being a pediatrician is seeing my patients and their families grow, change and achieve. I believe in preventative care. As pediatricians, we are the first line in ensuring that children are recognized, diagnosed and treated properly — often working like a detective with a magnifying glass — dosed with plenty of silliness and empathy. When I wake up in the morning I smile, knowing that I am doing exactly what I was made to do. Having trained in both Europe and the United States, I have been exposed to many perspectives on health care and wellness. I’m passionate about constantly striving to learn and improve myself to better advise and care for my patients and their loved ones. It is important to me to accompany my patients through to their young adulthoods, and help caregivers navigate our ever-changing health care system. I want my patients to feel comfortable with themselves, embrace a healthy lifestyle, and achieve to their potential. I hope to be a good listener and encourage a dialogue. Dr. Bollmann is highly rated in 19 conditions, according to our data. His top areas of expertise are Pulmonary Vein Stenosis, Ventricular Tachycardia, Paroxysmal Supraventricular Tachycardia (PSVT), Cardiac Ablation, and Thrombectomy.

Chad Crigger, M.D., M.P.H., is a pediatric urologist at Johns Hopkins Children’s Center and an assistant professor of urology at the Johns Hopkins Brady Urological Institute. He also serves as the Associate Program Director of the Urology Residency Program. After growing up in Charleston, West Virginia, Dr. Crigger attended the University of Richmond, where he majored in biology. After college, he returned home to West Virginia and obtained his medical doctorate from Marshall University and a master’s in public health from West Virginia University. He then completed an internship in general surgery and a residency in urologic surgery at West Virginia Ruby Memorial Hospital, where he was drawn to pediatric urology, particularly the reconstructive aspects that draw on principles from several fields including pediatric plastic surgery. This, and a chance visiting professorship by John Gearhart, M.D., inspired Dr. Crigger to pursue training in major reconstructive pediatric urology at Johns Hopkins, where he completed a fellowship. Relying on his background as a camp counselor, Dr. Crigger makes his patients active participants in their care whenever possible, often through sketching their condition. He is a member of multiple professional societies, including the American Urological Association and the American College of Surgeons. A researcher and director of pediatric urology research, he has published more than 50 articles in major journals and contributed to over 20 book chapters on pediatric urology. Dr. Crigger’s research focuses on his passion for major congenital anomalies, particularly the exstrophy-epispadias complex, about which he has multiple projects spanning the basic and clinical sciences. Additionally, with extensive training in robotic surgery, Dr. Crigger serves as director of robotic surgery for pediatric urology. His team looks for ways to safely apply the robotic surgery platform, including single port surgery, when feasible. His philosophy in practicing medicine is simple: to “provide the greatest benefit through the most up-to-date and least morbid treatment options possible.” Regarding providing care for patients and working with families, his focus is singular. When talking with parents, he can often be heard saying, “I know that, whether I am performing surgery or offering my professional recommendation, I am caring for one of the most important people in your life. I take that responsibility seriously and will do my very best to deliver the highest level of care possible.” Videos Chad Crigger, M.D.Pediatric Urologist.
