Meet our Veterinarians

Please click below to read biographies and meet the rest of our team.

Throughout my life, my pets have always been a part of my family. I am fortunate to have spent the last 15 years doing a job that I love. I am a lifelong Georgia resident and a Double Dawg earning my undergraduate in Animal Health as well as my Doctorate of Veterinary Medicine from the University of Georgia.

I have experience in emergency, critical care, and of course in our general practice that has been operating since 2011. I have an interest in dentistry and internal medicine, but I am passionate about the patient and client experience in our hospital. I enjoy working with the clients, patients, and staff so that each pet receives specialized care for their physical and emotional needs during their visit. I promote bribery with treats as often as possible each day.

When I am not at work, I am spending time with my wife, Allison, and my two children, Kate and Harrison. If I am not with them, I am in my garage feeding my woodworking addiction while I complete a home improvement project. If I come out the garage, I may be playing tennis. Our family pets are our two dogs Zoey and Tallulah, and Lucy our cat.

Dr. Sierra Morelli is from Woodstock, GA and received her undergraduate degree from Kennesaw State University with a Bachelor of Science. After graduating from the University of Georgia in 2014 with her Doctorate of Veterinary Medicine, she joined the Vickery team in 2020. Her special veterinary interests are internal medicine, feline medicine and nutrition. Her family includes her husband, Neil and two children Liam and Quinn, and of course two kitties Pepper Paws and Luna. When she has free time she enjoys reading, serving at church, and spending time with her family.

To provide advanced care for our patients, we have partnered with a mobile veterinary team. This partnership allows mobile specialists to visit our hospital and provide individual care to our patients.

Dr. Duval completed his undergraduate and veterinary school at the University of Pennsylvania. Derek and his wife, Julie Duval VMD DACVS, moved to Georgia where Derek did his internship at University of Georgia while Julie completed her residency in surgery. After his internship, Derek stayed on faculty at UGA and ran the Outpatient Medicine service for two years. The Duvals then returned to Philadelphia where Dr. Derek Duval completed his small animal internal medicine residency at Penn. During his residency Derek was responsible for setting up and starting the outpatient endoscopy service at Penn and completed research and publications on immune-mediated hemolytic anemia (IMHA). Dr. Duval completed his board certification in small animal internal medicine in 1997 and is a diplomate of the American College of Veterinary Internal Medicine (DACVIM). He has served the ACVIM in a variety or roles including credentialing, test preparation and rating and other volunteer services. Since leaving academia, the Duvals have been practicing high quality specialty medicine and surgery in the Southeast, including most of the last 20 years practicing in Atlanta. Dr. Duval is an accomplished endoscopist (both rigid and flexible endoscopy), ultrasonographer and diagnostician and enjoys all aspects of internal medicine and endoscopy. Dr. Duval has a special interest in interventional endoscopy and radiology, and has helped pioneer procedures such as tracheal and urethral stenting and balloon dilation treatment for esophageal strictures. Dr. Duval has lectured extensively locally and nationally on a variety of topics in internal medicine. The Duvals live in Atlanta with their dogs Bella (Shippereke) and Maisie (Sheltie) and a variety of frogs, lizards and turtles. They have two children who grew up in Atlanta and now are at UGA graduate school and GaTech engineering. When not practicing internal medicine, Derek is an avid homebrewer and martial artist and enjoys sharing music and outdoor activities with Julie and their kids.

After growing up in Kentucky and Texas, Dr. Duval received a bachelor of science degree from Duke University, then graduated summa cum laude from the University of Pennsylvania School of Veterinary Medicine and stayed on for a year to complete a rotating internship. She was happy to be able to come back to the south for her surgery residency at the University of Georgia and then accepted a position as a clinical surgery instructor at the University of Pennsylvania, where Dr. Duval was involved with the training of students, interns and residents.

After trying out two private referral practice jobs in Columbia, SC and St. Louis, MO, she and her husband moved to Atlanta in 2000 where they were two of the original specialists at one of the largest veterinary specialty practices in the southeast. Over 18 years of practice in Atlanta, Dr. Duval was able to gradually adjust her caseload to focus on soft tissue surgery. She also was very active in organizing and participating in the continuing education program at that practice. While enjoying all aspects of soft tissue and oncologic surgery, Dr. Duval has special interest in perineal urethrostomy, portosystemic shunts and reconstructive surgery.

Dr. Julie Duval has been married to internist Derek Duval since 1990, and they have two children who are studying at colleges in Georgia. She loves reading, watching college football and basketball (especially the Duke Blue Devils), hiking, travel and photography. She and her husband have two dogs, sheltie Maisie and schipperke Bellatrix, as well as some pets with no fur.

Dr. Arango attended the University of Florida for his undergraduate studies and veterinary school, earning his DVM in 2012. He then spent a year at The Ohio State University Veterinary Medical Center as a small animal medicine and surgery rotating intern. Dr. Arango returned to Florida to complete a surgical internship at Hollywood Animal Hospital and spent the following three years at the Oklahoma State University Center for Veterinary Health Sciences to complete his surgical residency. After working a speciality referral hospital in Northeastern Pennsylvania, Dr. Arango decided to relocate to Atlanta to expand the MOVES team there as an orthopedic surgeon. He enjoys all aspects of veterinary surgery, but he is especially interested in fracture repair and other areas of orthopedics.

Meet our Staff

Veterinary Technician

I joined our hospital team in 2015 after my family relocated to Cumming in 2013. I have been a licensed technician for fourteen years after completing my B.S. in Biology at Georgia Southern University and my A.A.S in Veterinary Technology at Gwinnett Tech. My career has been one of constant learning and growth. In order to keep my skills current and incorporate low stress patient handling into our hospital, I became a Fear Free Certified Professional in 2019. I love working with our team and appreciate our goal to be exceptional each day.

When I am not at work, my husband and I are cheering loudly for our son on the baseball field or clapping quietly for our daughter playing in the band.


Following an apprenticeship with a Master Groomer, I began my grooming career over 20 years ago. I became part of the Vickery team in March 2016 and have enjoyed working with our generous and caring staff. I was raised in Forsyth county and now my husband and I are raising our son here. We love to watch him play baseball or go fishing as a family.


I have been a part of the Cumming community for most of my life. I joined our team in 2011 when the hospital was established and brought seven years veterinary experience with me. I am a graduate of the Business Management Certification program at Lanier Technical College and studied at Piedmont College.

I am passionate about working with clients and their beloved family pets. My husband and I are the proud parents of an active little boy and have a dog named Cali. When I am not working, I enjoy reading or making memories with my sweet family.

Veterinary Assistant

I joined the Vickery team in 2019 after working in the veterinary profession for three years. I have enjoyed learning about and working with a variety of dog and cat breeds during my career. I enjoy learning something new each day and find the challenges to be rewarding. When I am not working, I am hanging out with my two dogs, Abby and Marley.

Veterinary Technician

I am an Air Force Veteran and have earned an A.A.S in Fire Science. I started in the veterinary profession seven years ago and have filled several roles in the hospital. After relocating to Georgia in 2019, I joined the Vickery team where I am continuing to expand my skills as a technician. I relocated from California and have enjoyed exploring this beautiful state. When I am not traveling, I am playing baseball, boxing or lounging with my cat, Tide.


I have worked with animals in several capacities over the last six years from pet retail, to wildlife care, and other roles that have led me to my current position as veterinary hospital receptionist. I joined the team in 2018, and I love the caring atmosphere and fear free approach to medicine and handling. My fiancé and I are looking forward to our wedding in April 2020. We currently have four cats and a bunny. When I am not wedding planning, I enjoy reading or taking my cat “Minky” on nature trail walks around this beautiful county.

I earned my technician and companion animal laser therapy certification at Mt. San Antonio College in California in 2003 and have been honing my skills in veterinary medicine since then. After moving to Georgia in 2019, I joined the Vickery team. When I am not working, I enjoy following several of my teams in baseball, football, and hockey. I love all my four-legged children and am looking forward to exploring Georgia.
