T. Lindsey Burrell, PhD is a licensed psychologist trained in treating common childhood concerns including behavioral, feeding, sleep, and toileting concerns in neurotypical and neurodivergent children. Parents are an essential part in treatment of any child concerns and as such Dr. Burrell specializes in parent-mediated intervention. Dr. Burrell is a certified trainer and therapist in the RUBI Parent Training Program, a structured intervention to reduce tantrums, aggression, and other behavioral challenges in children on the Autism Spectrum. Dr. Burrell also employs a cognitive behavior therapy (CBT) approach to teach children how their thoughts and feelings affect their behaviors and to develop positive thought patterns and effective coping strategies. Dr. Burrell focuses on skill building and functional communication to reduce verbal and physical aggression, tantrums, and oppositional behavior.

Dr. Burrell also has extensive experience in working with children with moderate to severe feeding difficulty including food refusal and feeding tube or formula dependence and food selectivity or eating a limited variety of foods. Due to the multifaceted etiology and impact of feeding problems, Dr. Burrell works collaboratively with multidisciplinary providers (e.g. dietitians, speech pathologists, physicians) to address feeding concerns. Treating feeding concerns may involve individual work with the child, parent training (without the child) or parent coaching (with the child).

Michell Mastin, PhD


Dr. Michelle Mastin is a licensed clinical psychologist with over 17 years of clinical experience within hospital settings integrated among multidisciplinary specialties. Dr. Mastin was trained primarily as a behavioral psychologist with extensive training in the behavioral and familial management of common childhood challenges including noncompliance, tantrum behavior, challenges with sleep, toileting, and eating. Dr. Mastin’s training supported her eventual development of a specialty in the treatment of children and adolescents with challenges related to the gastroenterology tract. Challenges include matters involving feeding, rumination disorder, abdominal pain, encopresis and other disorders of the gut-brain interaction. Because children with GI challenges often have significant difficulties managing anxiety and stress, Dr. Mastin also specializes in the treatment of anxiety.

Dr. Mastin started her career as a general pediatric psychologist and then as the co-founder and director of the Helen DeVos Children’s Hospital Intensive Feeding Program. After 8 years, she was asked to establish and direct the Children’s of Alabama Intensive Feeding Program. During her 8-year tenure at Children’s of Alabama, she was integrated not only with children with feeding disorders, but also children with GI disorders and children with chronic medical challenges. For the last 3 years, when she decided to transition from hospital-based services to private practice, she continued to work with Peyton Manning Children’s Hospital Feeding Program while simultaneously working in private practice in effort to meet the needs of children, adolescents, and families with a more tailored approach to treatment. She has held clinical assistant professor appointments with the Department of Pediatrics at the University of Alabama at Birmingham and with the College of Human Medicine at Michigan State University.  


Dr. Mastin received her Bachelor’s Degree from Emory University and pursued her doctoral education in Clinical Psychology at the University of Mississippi. Dr. Mastin completed her internship and post-doctoral fellowship at the Kennedy Krieger Institute at the Johns Hopkins University School of Medicine.

When not working with children, Dr. Mastin enjoys spending her time with her husband of over 20 years, their three children, and family dogs. She lives in Sandy Springs and you can usually find her watching her children on a baseball field, basketball court, or exploring Atlanta and the surrounding areas with her family.
