    Dr. Deepika Thacker is a pediatric cardiologist and assistant professor of Pediatrics at Jefferson Medical College. She’s a member of the American College of Cardiology, American Heart Association and American Society of Echocardiography; an invited lecturer; and an author of journal articles, book chapters and abstracts. I first thought about medicine when I was young and doctors discovered a hole in a friend’s heart. From that moment, I decided I wanted to become a doctor and help children with problems like my friend’s. I never wanted to be anything else. Medical school and my medical training reaffirmed this decision. There is an added attraction to cardiology in that it provides a challenging field of medicine to study — the mix of anatomy and physiology is almost like math or engineering, and I enjoy it very much. Becoming a mother further validated my career choice for me. I see something of one of my own children in every child I treat.I’m happiest when I’m caring for children.. There’s no better feeling for me than when I’ve helped a child get better. At the end of every day I am thankful to be able to do what I do. I always want to make sure that every child gets the best care and treatment, and that we do everything possible for that child. My role is to help each child get the most out of each day. In addition to the care I deliver as a cardiologist, I also try to make a difference every day through my role as medical director of the hospital’s 2B cardiac unit. As we move to more unit-based inpatient care, we’ll continue to always look for ways to improve the great care we give. I’m excited to be a part of that. We’ll continue to work so that patients being discharged can go home sooner. We’ll continue to work to reduce readmissions. And we’ll continue to explore what it means to deliver true family-centered care — making parents and families part of our medical rounding and decision-making. Dr. Thacker is rated as an Experienced provider by MediFind in the treatment of Williams Syndrome. Her top areas of expertise are Multisystem Inflammatory Syndrome in Children (MIS-C), Kawasaki Disease, Pediatric Myocarditis, Myocarditis, and Heart Transplant.

    I enjoy being a physician, taking care of the kids and the kidneys and helping families in their medical journeys, no matter how intense or mild and regardless of the outcome. These families trust us and our opinions with their children and keep faith in what we say and recommend. This whole process is very humbling and gratifying at the same time. I was drawn to pediatrics because of my observations noting the resilience, the sincerity and honesty in children’s responses to various life stressors, including diseases. Their resilience to both the psychological and physical demands and stresses of illness never stopped surprising me. And then, at the end of the journey, their ability to recover and bounce back has continued to be the greatest satisfaction for me. I am most passionate about bringing the most up-to-date methods of medical care to all my friends (patients) regardless of their background, socio-economic status, culture or geographical challenges. I feel that our job is to eliminate the discrepancies in access to medical care and treatment to the best of our abilities, simply because there is no point in having a solution for a problem, no matter how magical it might be, if the solution cannot be applied to everyone in need of that solution. I try to make a difference by being a good listener. I give my best effort to listen well and to understand what is being told to me. It is my first goal that my friends and their families will feel that they were given enough time to explain their course and concerns. And following that, I try my best to interpret the information given and come to conclusions. Then, I share my thoughts, outcome possibilities and our approach plan with honesty so that both my friends and their families have an understanding of their condition. Without sugar-coating or tap-dancing around the topic, I try to give my best explanation with the information available, sharing with them that the given opinion may always change, to the worse or better, as more information flows in.

His top areas of expertise are Nephrotic Syndrome, Feingold Syndrome, Congenital Nephrotic Syndrome, and Glomerulonephritis.

    I’m pretty even-keeled. Because I wanted a profession I could have a lifelong passion for, and felt drawn since childhood toward medicine, I chose pediatric surgery. It’s fulfilling on a daily basis – not just the actual surgery, but also the opportunities to communicate with patients and families and establish bonds with them. For me, pediatric surgery is the most rewarding of all fields – for many reasons. Children are innocent, resilient, and fun to take care of. The kids I see are afflicted by an accident or bad luck, and it’s great to have a positive impact on them and their families. I feel strongly about spending time with parents – after all, they’re entrusting their child’s care to me and my team. It’s a privilege and a responsibility to establish a bond with them. I take this aspect of my work very seriously. I’m also passionate about doing the right thing, being a good family person, raising my kids to be wholesome children who grow up to be good, happy people. Recently I tied with another physician for the highest patient satisfaction score at Nemours. It’s not the kind of award you actively try to win – I didn’t even know I was competing at all – but it’s something I take pride in. It was a welcome surprise, and it’s satisfying to think I’ve made a positive impact on children and their families.

    I think I’m just drawn to children; they’ve done nothing wrong to lead to any of their illnesses. I think that’s a really easy group to take care of, and one that gives a lot of satisfaction when I’m able to help them. I also really like working with parents — working with them to guide and reassure them. That really goes miles towards helping parents care for their children. I definitely enjoy being able to connect with a whole family and helping them through their child’s illness. I’m passionate about early childhood development and intervention — care that can help children’s special needs be identified earlier, and get into services that can help a child be successful sooner. My top priority is making sure that I do the very best for a child, and that parents understand my thinking and why things are happening.I also love the continuity of care I can give to families. I love being able to see children grow, and being able to follow them over time. I like learning who the children are, who their families are, and watching children grow and develop, both from a medical and a social-emotional perspective. I really value the education and training of new physicians, the academic aspect of medicine. I want to stay involved with teaching residents —the formal training, and also modeling ways of teaching, talking to parents and offering guidance.

Her top areas of expertise are Autism Spectrum Disorder, Developmental Dysphasia Familial, Cantu Syndrome, and Simpson-Golabi-Behmel Syndrome.

    I’m a proud father of two with two on the way. Being a dad has opened a new door in my life — it’s helped me realize even more how special children are and what family means. I enjoy spending time with family, doing anything outdoors and watching sports. I’m originally from the Bronx, but grew up in Florida and am a lifelong Florida Gators fan. When I was in high school, my older sister was diagnosed with a rare form of pediatric cancer. It required her to get specialized treatment. She at the time was 18 and was looked up to by all the other pediatric patients as a role model, and sometimes even as a babysitter. Her impact on those kids made me want to do something for kids, too. I’m passionate about making sure that children can still experience life as children regardless of their circumstances, location or sickness. I think it’s important to help kids maintain a sense of innocence and fun throughout the process of something as serious as open-heart surgery. I try to make a difference by actively listening to patients and families, offering continued support, having a willingness to research new therapies, and providing seamless communication with primary care providers. I think it’s very important to provide constant feedback and communication for families and involve them in decision-making.

    What is the definition of Williams Syndrome?

    Williams syndrome is a rare disorder that can lead to problems with development.

    When should I see a Williams Syndrome doctor in Delaware, US?

    There are various reasons why you may want to see a specialist, such as: 

    • Your primary care provider recommends it. 
    • Your condition requires expert knowledge and specialized care. 
    • Your symptoms persist or worsen despite treatment. 
    • You need specialized testing or procedures. 
    • You want a second opinion.  

    What should I consider when choosing a Williams Syndrome doctor in Delaware, US?

    It’s important to see a provider with expertise in your specific condition. Each provider profile in MediFind’s doctor database includes information on which conditions they treat, years of experience, research contributions, languages spoken, insurance plans accepted, and more.  

    How does MediFind rank Williams Syndrome doctors in Delaware, US?

    MediFind’s rankings are based on a variety of data sources, such as the number of articles a doctor has published in medical journals, participation in clinical trials and industry conferences, as well as the number of patients that provider sees for a given condition. Note that MediFind’s provider database is not based on user reviews, and providers do not pay to be included in the database. 

    What types of insurance are accepted by Williams Syndrome doctors in Delaware, US?

    Most profiles in MediFind’s doctor database include a list of insurance plans accepted by that provider. However, it’s a good idea to contact the provider’s office to make sure they still accept your insurance, then doublecheck by contacting your insurance plan to confirm they’re in network. 

    How can I book an appointment online with a Williams Syndrome doctor in Delaware, US?

    MediFind offers direct scheduling for certain providers using the “Request Appointment” button on that provider’s profile. If the schedule option is not available for a provider, tap the red “Show Phone Number” button on their profile to get their contact information. If you prefer to find providers who offer online scheduling, select “Schedules online” under the “Availability” category of the filter feature on the left side of the Williams Syndrome doctor search results page. 

    Why is it important to get a second opinion from a different Williams Syndrome doctor?

    Second opinions are an opportunity to confirm a diagnosis and its root cause, learn about alternative treatment options, or simply gain peace of mind. Many people, especially those with serious diagnoses, get second opinions so they can understand all their options and make informed decisions, so don’t hesitate to get one if you have any doubts or need more information or clarification regarding your care. Note that some insurance plans require second opinions, while others don’t cover second opinions, so be sure to confirm with your insurance provider first.   

    How can I prepare for my appointment with a Williams Syndrome doctor in Delaware, US?

    Prepare for your appointment by gathering the following items: 

    • Copies of medical records (dating back at least one year) 
    • Your medical history, including illnesses, medical conditions, surgeries, and other doctors you see 
    • Family history of disease 
    • List of current prescription drugs, over-the-counter medicines, vitamins, and herbal remedies or supplements including names and doses 
    • Allergies to medications, food, latex, insects, etc.  
    • List of questions and concerns 
    • Your insurance card 

    You might also contact the provider’s office to see if they offer transportation or childcare services or if you’re allowed to bring a loved one for support or to take notes during your visit. 

    What questions should I ask my Williams Syndrome doctor?

    Here are some sample questions: 

    • Can you explain in simple terms what this condition is and how it’s treated? 
    • What symptoms or side effects should I watch for? 
    • What tests will be involved, and when can I expect results? 
    • Are there other specialists I need to see? 
    • What’s the best way to reach you if I have follow-up questions? 

    How can I learn about the latest clinical trials and research advances my Williams Syndrome doctor may know about?

    MediFind’s Clinical Trials tool asks you a series of questions to help you narrow down your search by health condition, age, gender, location, how far you’re willing to travel, and more. Each question you answer filters down the number of trials until you find the ones that are most relevant to you. 

    MediFind’s Latest Advances tool features summaries of recent articles published in medical journals. We use cutting-edge technology to scour medical publication databases for the latest research advancements on any given condition, then we simplify this information in a way that’s useful and easy to understand. 

    Can I filter my search to show male or female Williams Syndrome doctors in Delaware, US?

    Look for the filter feature on the left side of the Williams Syndrome doctor search results page. Select “Female” or “Male” under the “Gender” category to search for female or male providers exclusively. If the “Any” option is selected, it will pull results for both male and female providers. 

    Can I filter my search to find a Williams Syndrome doctor that offers video calls?

    Look for the filter feature on the left-side of the Williams Syndrome doctor search results page. Select “Offers telehealth visits” under the Availability category to search for providers who offer virtual appointments (video calls).
