Our Providers

Edward Perl, M.D., F.A.A.P.

Edward Perl, M.D. has been practicing Pediatrics and Adolescent Medicine in Carroll County since 1977. He received his B.S. from The George Washington University in 1969 and then taught high school Biology in Baltimore City for one year. He received his M.D. from the University of Maryland School of Medicine in 1974 and then completed a three-year residency program in Pediatrics and Adolescent Medicine at the University of Maryland Hospital. In 1980, Dr. Perl received his Pediatric Board Certification. During his early years in practice, he also served as Director of Child Health Services for the Carroll County Health Department, initiating many youth programs such as the Scoliosis Screening Program in the Carroll County Schools, the first scoliosis screening program in Maryland.

“Being married for more than 44 years and as a parent of four, I have a great appreciation of the challenges that come with raising a family. Good parenting is incredibly demanding, time consuming and rewarding; and none of us are immune to the multitude of frustrations that parents must face all too often. Practicing Pediatrics is not just about sick kids. It’s developmental, academic and emotional issues; it’s supporting the parents; and it’s being the ‘go-to person’ when it comes to any aspect of your child’s well-being.”

“I practice Pediatrics because I love it. My families are great and many of them are now second generation with me. I have fun with the kids and enjoy them at all ages – spending a lot of time in the office or on the phone making myself available to address concerns. Whether it is a complicated medical issue, a routine check-up, or a college student calling with certain anxieties, I am always interested and available. There is nothing boring in my day at the office.”

Timothy Perl, M.D., F.A.A.P.

In July 2014 Timothy Perl, MD, F.A.A.P., also a Board Certified American Academy of Pediatric Pediatrician, joined Carroll Pediatric Center as a full time Pediatrician. Having Tim join our group has allowed us to increase our regular evening and weekend office hours in addition to having him in the office every weekday. Tim Perl, MD, the son of Edward Perl, MD, received his Bachelors of Science degree from Tulane University before receiving his M.D. Degree from St. George’s University School of Medicine. He completed his Pediatric Residency at SUNY Downstate Medical Center in New York.

Tim is an extremely bright, dedicated, caring and gentle physician, who has the natural gift of connecting with people and making any child smile. “I love science and learning, but the best part of practicing Pediatrics is getting to know and helping all of our families.”

His wife, Sarah, is an RN graduate from Johns Hopkins, a Pediatric Nurse Practitioner graduate from NYU and is a Pediatric Nurse Practitioner at Johns Hopkins Hospital. They have two delightful children, Quinn & Joey.

Sarah Zader-Weinstein, M.D., F.A.A.P.

Sarah Zader-Weinstein, M.D. is an American Board of Pediatrics certified pediatrician who is joining Carroll Pediatric Center in October, 2022. After graduating from the University of Maryland Honors Program with a Bachelor’s of Science in Biology and Psychology, Dr. Zader attended The George Washington University School of Medicine where she was awarded membership in The Gold Humanism Honor Society. She subsequently completed her pediatric residency training at Naval Medical Center Portsmouth in Virginia. Prior to joining Carroll Pediatric Center, she worked as a general pediatrician and was a Major in the United States Air Force stationed at Andrews Air Force base, where she was the Pediatric Graduate Medical Education Site Director. She also covered pediatric services at Walter Reed Medical Center and Fort Belvoir Community Hospital. She was an Assistant Professor in Pediatrics for the Uniformed Services University of the Health Sciences in Bethesda, Maryland. Dr. Zader has published multiple publications, including the journal of the American Academy of Pediatrics.

“I could not imagine working in another profession. I absolutely love being a pediatrician. I find such joy in developing connections with my patients and their families. Working as a pediatrician, I get to apply my love of interacting with others and my love for science. It is an honor to help families navigate every milestone from infancy to adolescence.”

“Having two children of my own, I understand the wild but happy journey of parenthood. I hope to always be a source of support to my patients and their parents. I will be here to help during times of illness and to provide proactive care and guidance at well visits.”

Rebecca Theise, MSN, CRNP, CPNP-PC

Rebecca Theise, our pediatric nurse practitioner, joined Carroll Pediatric Center in 2021. She completed her Bachelor’s degree in Community Health at Brown University in 2010. After working as a refugee health care coordinator in New Haven, CT, she earned an RN and Master of Science in Nursing from Yale University’s pediatric nurse practitioner program. Rebecca became board certified as a Primary Care Pediatric Nurse Practitioner (CRNP, CPNP-PC) in 2015, and since then has worked at pediatric private practices in Connecticut and Maryland. In her free time, she enjoys rock climbing, biking, reading fiction, and exploring the outdoors with her husband and son.

“Part of what drew me to pediatrics is the focus on the whole child — their family, their school, their home environment, their hobbies, even their pets! We know that if we can understand where they’re coming from, and if we can truly partner with their families, then we can help them achieve optimal health for years to come. As a new mom myself, I can empathize with parents on a whole new level and better support them on their childrearing journeys.”

Rebecca loves working with children of all ages — whether it’s helping new parents gain confidence with their newborns, making check-ups fun for toddlers, talking about nutrition with middle schoolers, or helping teenagers feel empowered about their health. “It is an honor to be a part of their growing-up.”
