Welcome to Bear Pediatrics

After over 9 years as a Pediatric Nurse Practitioner, I opened my own pediatric and newborn office on Belair Road to help families in Baltimore, Harford, and Cecil County. My goal is for everyone to feel at home in the office, feel like they have all my attention (which you do!), and leave feeling like their child got the best and most personalized care ever! I want everyone to feel that they can just come on in, sit down, and have a quality conversation with me… just like the old days! No rushing in and out! I want to know your name and all about you… like family! Because at Bear Pediatrics, you are family!

Meet Katie Cassett

Hi everyone! My name is Katie Bittner-Cassett and I am a Certified Registered Nurse Practitioner (CRNP)… but please just call me Katie! I started my career in nursing in the Emergency Room of Franklin Square Hospital in 1999 after I graduated from Villa Julie College with my Bachelors of Science in Nursing. I worked there until 2004 when I moved to the Pediatric Emergency Room at St Agnes Hospital in Baltimore and that is where my love of the pediatric population grew! I decided in 2008 to return to school to get my graduate degree in order to continue to advance my pediatric career. I graduated in 2012 from University of Maryland School of Nursing with my Pediatric Nurse Practitioner degree. I have worked the last 10 years as a PNP in primary care along with 3 years as a PNP in Sinai’s Pediatric ER prior to opening Bear Pediatrics in 2019.

Outside of the office, I have an amazing husband who is an exceptional firefighter for the Baltimore County Fire Department and I am also the very proud mother of the cutest 6 year old little boy who is my reason for everything… including this practice! I want to show him that you can do anything your heart desires and even if you fail, at least you tried!

Thank you for visiting my web page and I hope to see you at the practice! Feel free to contact me with any questions or concerns!

What Our Patients Are Saying:

If you want a pediatrician that is up-to-date in diagnostic skill, a child-friendly attitude appropriate to their age, a sharp memory, great follow-up, dedication to excellent care, wonderful face-to-face communication, and appropriate knowledge in procedures when faced with serious problems, you can’t do better than Katie! She has been our pediatrician since our son was a newborn, I feel like we have been in very skilled hands and I would highly recommend her to any families looking for truly compassionate and knowledgeable care!

Shannon Crowder

Katie truly treats her patients the way she would want her child to be treated. My son was terrified of the doctors and now all I have to say is “we’re going to see Dr. Katie” and he’s good to go. She’s personable and tries to find an interest to connect with her patients to make them feel at ease, after all a young child in a big room can be a little intimidating to them. I also bring my newborn daughter to see her and she’s helped correct some feeding issues that were causing rapid weight decline. She’s very responsive and you will definitely leave her office feeling confident in her diagnosis.

Stacie Cammarota

From the first time we met with Katie before having our son, we knew immediately she is who we wanted to work with as our son’s pediatrician. We felt so comfortable and cared for right away. Our son, now almost 2, loves seeing Katie! She has always been so thorough and caring as if he’s her only patient. I can’t say enough good things about her and am so grateful for her heart for children!

Sarah Jackson

Words cannot express the quality of care my son has received from Katie. We have seen many doctors and they all disregarded my concerns with ear infections and reflux. Katie has treated my little guy and we have a MUCH happier and healthier baby. As a new mom, I had many concerns and worries and she always put me at ease. To this day, she will take time away from her own family to talk to me. She is the sweetest and most gentle provider and I will not go to anyone else!

Lindsey Kneten

What can we say about Katie that even comes close to describing how amazing she is? She was an amazing support as we lost our firstborn to cancer and she continues to be an amazing support as she encourages us and tempers our anxieties with our rainbow baby.

She is patient, supportive, friendly, knowledgeable, and nurturing. She fields my millions of questions with a smile. She’s cried with us, and celebrated with us. She has become a true friend to our family and we can’t imagine taking our child anywhere else. We’re so excited about her practice and refer everyone to her and her excellent care!!

Lauren and Moises Frias

Katie has built a wonderful caring practice! She treats all her patients as if they were her own family! We are incredibly thankful for her!

Kerry Lisiewski

Absolutely love Katie and so do my boys! I love that i can send a message at any time….Katie is so quick to respond and so helpful!

Megan Esworthy

My family and I cannot thank Katie enough! She came into our lives 4 years ago when my youngest was born. He’s had quite the journey over the last 4 years die to some developmental delays. She was with us through it all. Most recently, my oldest (who has Crohns disease) ended up in the hospital for 10 days. If it was not for Katie seeing my message at 9:30pm on a Sunday night and CALLING me at home, I know things may have ended up very different. She and this practice are like no other. I’m so glad she can continue to once again be out provider and also our friend!

Laura Onesi Matthai

My son, Zachary, has been cared for by Katie since he was a week old. She is the true definition of what I was looking for in a pediatrician. She goes above and beyond to make sure my son has the best care and I am forever grateful for that. We love her!

Jessica Smythe

Katie is absolutely THE BEST.  Our journey with her began the day our daughter was born. She has literally been there from day one. We haven’t even had our first official appointment with her at her new office and shes been available over messenger to answer any and all questions and concerns I’ve had regarding my daughters health. We are so fortunate to be able to call her “ours”.
