    Dr. Jeffery Campbell has been a pediatric neurosurgeon at Nemours for 20 years. His most notable work is with kids that have skeletal dysplasia and he acts as the neurosurgical component of our larger skeletal dysplasia program at Nemours. Most of his research has been in dwarfism and osteogenesis imperfecta (OI). Prior to Nemours, he worked in a private practice in Charleston, SC. When I was in medical school, I knew that I wanted to do something “brain-related.” During my fourth year, I did a neurology rotation and thoroughly enjoyed the immediate feedback of surgery. I split my residency time between pediatric and adult hospitals, but quickly realized that I loved working with kids. I was able to see kids get better and found the impact I had on them gratifying. My goal as a doctor is to have a long-term impact on someone’s life and treating kids was my path to do just that. I am passionate about providing the best possible care for all children. I enjoy being on the cutting edge of treating rare problems on the skeletal dysplasia spectrum and I take pride in people traveling to Nemours from all over the country to seek such treatment. I love that I can do things that can’t be done anywhere else. I believe that health care should be a team sport. I always advocate for team approaches, especially with complicated cases. I actively create multidisciplinary teams for many of my patients to give them the very best care. Dr. Campbell is rated as a Distinguished provider by MediFind in the treatment of Achondroplasia. His top areas of expertise are Achondroplasia, Increased Head Circumference, Spondyloepiphyseal Dysplasia, Bone Graft, and Adenoidectomy.

I am passionate about being an advocate for improved health care and improved access to society for children and adults with disabilities. I truly try to treat each child and each family how I want my children and my family treated.

    I chose orthopedics because I love helping people get back on their feet, and I looked at how happy Orthopedic surgeons were 20 years into their practice. That is always a good sign that you have chosen a career path wisely! I was once a kid myself! Growing up I was a babysitter and a nanny, so I kind of grew up around kids. When I did mission work in Guatemala, I gravitated toward taking care of children. When I became interested in pediatric orthopedics, I started focusing on deformity correction because that mostly affects children. I’m passionate about being a doctor in general, and a doctor at Nemours in particular. Also, I think it’s important for people to learn to take care of themselves. As health issues, smoking and obesity are personal hot-buttons for me. I love what I do, and enjoy the interaction with parents and kids. I treat the whole patient as an individual, not just their orthopedic needs, and I treat each child as my own.

    I was born in India to a family of doctors, so I did not have to look far for inspiration. I’m married to a pediatric cardiologist, also with duPont Hospital for Children, and I’m grateful for the opportunities I have every day to improve lives for kids and their families. As a father and surgeon, I have a soft spot for helping children in any way I can. It’s a privilege to be able to improve their lives even if there are challenges. I love to see kids getting back to enjoying life to its fullest and being able to help people deal with difficult issues. One of my proudest professional moments was the day I walked into the operating room and had the privilege to start surgically caring for children. I’m still passionate about my work and the opportunities I have every day to improve the lives of kids, one child at a time. The children I treat have serious medical problems, and it takes a whole team of professionals, working in lots of related medical and sociological fields, to make a difference in their lives, and the lives of their families. It’s an honor to be part of that team. At the end of the day, it’s all about the kids. Dr. Thacker is rated as an Experienced provider by MediFind in the treatment of Achondroplasia.

    What is the definition of Achondroplasia?

    Achondroplasia is a disorder of bone growth that causes the most common type of dwarfism.

    When should I see an Achondroplasia 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 an Achondroplasia 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 Achondroplasia 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 Achondroplasia 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 an Achondroplasia 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 Achondroplasia doctor search results page. 

    Why is it important to get a second opinion from a different Achondroplasia 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 an Achondroplasia 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 Achondroplasia 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 Achondroplasia 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 Achondroplasia doctors in Delaware, US?

    Look for the filter feature on the left side of the Achondroplasia 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 an Achondroplasia doctor that offers video calls?

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