It’s like having a doctor in the family.

Over three generations of families are a part of the Jacksonville Pediatrics practice. It’s no wonder that moms and dads, and even grandparents, return to our pediatric practice with their children and grandchildren; it’s a family tradition. Established in 1948 by Dr. James Lanier, the fundamental values: love of children and staying abreast of the latest medical advancements and technologies, remain firmly entrenched.

New Jacksonville Pediatrics members are carefully screened for their professional credentials, certifications and their outstanding academic achievements. As a closely knit group, we think of ourselves as a second family, we want professionals who share our ideals: excellent listeners, a parent’s advocate, the ability to befriend children and gain their confidence, and a person who brings to our office unbridled enthusiasm, energy, and a love of their chosen profession.


Dr. Randolph Thornton

I’ve been described as a big kid, that’s probably why our patients feel so relaxed and comfortable when they have to come in. Teaching families about their conditions and treatments, I use models, drawings, charts, and hand outs. I am able to reassure mothers who are struggling with breast feeding or who have a child who isn’t walking or talking on time. I take how ever long I need to thoroughly understand how a child is feeling, search for the causes, and always spend time answering every patient and parent question.

My two children have provided invaluable lessons regarding the art and practice of pediatrics. I have gained respect for the challenges parents face in such things as getting young children to take their medicine, eat their veggies, handling them when ill and facing developmental concerns.

Often the most powerful reason parents give for deciding on a particular vaccine or treatment plan is because I tell them it’s what I’ve done for my own children. I never have, nor will I, ever offer any procedure, vaccine, or therapy that I would not offer my own kids. I think of all my patients as my kids.

In 1986 the chairman of my residency program recommended me to join this busy and popular practice which has been treating Florida and Georgia families since 1948. It thrills and humbles me to watch my patients grow up in this practice and then start bringing in their own children.

Dr. Nan McClelland

I love being a part of Jacksonville Pediatrics. My goal is to really listen to parents and patients and take the time necessary to understand them and communicate well. More than two decades of practice has made me more intuitive, patient, compassionate, and a better doctor.

As a Christian, my goal is to approach patients and families as a “whole” because social and spiritual issues directly impact our health and lives. Daily, I pray that God will use me to positively influence the lives of the children, teens, and families that honor me with their trust. It is a joy for me to serve my patients and their families in the best way possible, whether we need to carve out extra time to deal with a complex problem or find time for a quick visit or answer a parent’s phone call.

Whether it is preventing disease by immunizing, treating illness, or enabling a patient to do better in school, improving a child’s quality of life is the most rewarding part of our pediatric practice.

Dr. Jennifer Savarese

(Formerly Dr. Chally.)

I take my daughter to work everyday. Not literally of course, but my mom experience helps broaden my perspective about children, making me more realistic and empathetic, especially when it comes to their emotional development and behavior.

Not every ill is cured with a prescription. Children often come see me not feeling well because they are stressed out and physical symptoms present themselves. It is no wonder they are stressed. Today kids are the busiest, most scheduled of any generation. They feel the stress of living up to the expectations of their parents, their teachers, their coaches, and, most importantly, themselves. Sometimes all this adds up to headaches, stomach aches, or just some indescribably feeling of the blahs.

Eliminating a child’s stress is important. Kids have such a great perspective on life. When we give patients the time to relax they can express their thoughts and worries and the parents have time to share their concerns. When I observe both my patient and their parent start to relax, I know they will work together, finding ways to take the stress out of everyday and get back to enjoying life. For me, that’s a great day at the office.

I worked as a medical assistant at Jacksonville Pediatrics before medical school and found the doctors to be a great bunch of caring physicians and I knew then I wanted to be a part of this practice. I’m so glad I’m here.

Dr. Ryan Cantville

For me, pediatrics was a natural choice. I get to work with kids all day; which is the best job in the world, especially since I’m a big kid at heart! Kids appreciate that I take time to ask them questions and that I am interested in what they have to say. I listen to what they tell me – and to what they don’t. Both can have an impact on their physical and emotional health. Sometimes they need a hug after a vaccination, a high five for great grades in school, or encouragement when they’re struggling.

It is also important to me that parents share their insights and instincts about their children, so we can be partners on their kids’ health care team. I’ll be right here for them and their child; from the day they make their arrival, until we all wave them off to college. Watching kids grow and thrive is such a thrill and privilege. The biggest praise is when friends and colleagues have chosen me to be their child’s pediatrician.

In November 2014, my wife Adriana and I were beyond thrilled with the arrival of our son Gabe, but it was not without hurdles. He was born with a head and neck mass that would require him to have a tracheostomy to help him breath when he was only a few days old. His journey has been transformative. I found myself on the other side of the stethoscope and playing a totally different role on his health care team. His medical complexities and the challenges he faces daily can be daunting. Parenting is more difficult than anything I had ever imagined, but Gabe’s smile and laughter make even the toughest of days a pure joy. I have learned more about pediatrics over the last two years, as Gabe’s father, than I did in most of my training. Because of him I am a better person and a better pediatrician.

Along with my love of medical science, I channeled a new and heightened sense of empathy into my patient’s care, becoming a better patient advocate. We have been so fortunate to have access to the best doctors and specialists in town and to be able to provide Gabe with the very best care. I am committed to provide my patients with that same love and dedication.

Dr. Tom Stanley

34. That’s the number of kids in my family: my grandparents (19), my parents (10), and my wife and I have five. I’ve experienced a lot and heard many stories, all of which is helpful in my work with patients and their parents. There is an excellent chance that I’ve experienced what they are going through, particularly with behavioral approaches and training techniques.

Working with kids and helping them grow up healthy and strong makes me happy. I’ve been privileged over the years as a volunteer at an orphanage in Jamaica and as a coach for my children’s teams. When a child smiles because I’ve helped them feel better or learn a new skill it makes me feel great.

Now, after almost 25 years with Jacksonville Pediatrics, I have decided to reduce my hours to several days a month. I want to continue serving my patients while also pursuing other charitable endeavors that are dear to me. My wife, Julia, and I are thrilled to have more time to indulge our three grandchildren.

Pam Wentworth, Nurse Practitioner

Keep Calm and Carry On*. As a neonatal ICU nurse at Baptist Hospital the care of critically ill newborns was a daily emergency. This intensive, and often exhausting, experience of caring for the tiniest babies, with life threatening medical problems, was one of the most rewarding positions I’ve ever had.

Along with my academic training, my ICU experience has proved to be an incredible foundation for my two favorite jobs: being a mom and working as a Nurse Practitioner at Jacksonville Pediatrics.

When our patients call the office with a sudden illness or medical situation, such as fevers, rashes, sore throats that could be strep throat, or any one of the bugs children pick up at school, our parents know that they can call or bring in their child immediately and I can help both the patient and their parents relax which is one of the first steps to feeling better.

I love being a mom, it’s something new almost everyday. Being involved with my children’s activities at school, church and scouting has also expanded my first hand understanding of how children develop differently, physically and behaviorally. This, of course, has been very beneficial as I work to help my patients and their parents learn about dealing with different situations or helping them understand the value of developing healthy living habits.

When the days are busy and rushed, and really, that’s every day, I just say to myself, stay calm and carry on!

Cathleen “Catie” Southall

Being a nurse made me a better mother and being a mother made me a better nurse. I’ve been there – the new, exhausted, breastfeeding-every-two hours-throughout-the-night mom. I know first hand what it’s like getting an active toddler to take breathing treatments. Becoming a parent gave me a new understanding and deeper appreciation for the worry and joys of parenthood.

I feel confident saying my patients look forward to coming to our office and seeing me. When they come in for a well-check I put kids at ease so they feel like we’re friends catching up. Parents tell me their children ask if they can come see me when they aren’t feeling well because they know I will make them feel better. I love my job!

The trust of my patients means everything to me. It indicates my patients believe that I listen to them and take time to understand how they feel and how they are feeling – which is not always the same thing. As a result I’m better able to help their parents make the best decisions for their health. It’s very rewarding when kids leave feeling better and parents feel less stressed and more confident.

At Jacksonville Pediatrics we treat our patients and families as I always have treated mine, like a member of my family. It’s inspiring, and a testament to the superior care patients and their parents receive, that former patients bring their children here.

I enjoy being a life-long student and annually renew my pediatric certification. This requires extensive pediatric continuing education classes which help me stay abreast of the latest developments in all facets of pediatric health and well-being.

Sara Pyle, Nurse Practitioner

I watch my friends diligently do their research to make smart decisions for the health and well being of their children and many decide that Jacksonville Pediatrics is the right choice for their kids.

I’m thrilled to be a part of the Jax Peds family so I can use my professional skills and talents to care for everyone’s children, from newborns to adolescents and everywhere in between.

My journey to becoming a nurse began as a young girl myself. I have always enjoyed science and later became interested in medicine. My career path was set when I realized I could combine both and have the ability to help kids.

Working as a registered nurse for three years in the Hematology/Oncology and Bone Marrow Transplant Unit at Wolfson Children’s Hospital afforded me the opportunity to build a strong nursing foundation so that I can continue to provide all families of my patients with supportive care.

Now I use my training and past experiences to help children relax in a tense or challenging situation. When possible, I like to have the child involved in their exam and care. I strive to have a calm and relaxed approach in order to achieve this reality.

I have a particular love for babies and toddlers – sometimes as I watch them develop and grow between check-ups I think I am as excited as their parents by their latest milestone.

I am excited and thankful for the opportunity to be with Jacksonville Pediatrics as their newest Nurse Practitioner. I look forward to helping all of our young patients grow into happy, healthy adults, and am proud to be part of this great team.
