Dr. Patrick Long
Dr. Long attended medical school at the University of Cincinnati College of Medicine and completed a Family Medicine residency at the Detroit Medical Center and a Medical Genetics residency at the University of Colorado School of Medicine. His fellowship in Medical Biochemical Genetics was completed at the Children’s Hospital of Colorado. Patrick currently lives in Denver and specializes in the diagnosis and management of genetic disorders and inborn errors of metabolism in adults.
Dr. Chelsie Hollas
Dr. Hollas grew up in Bryan, Texas. She attended Texas A&M University for her undergraduate and Master in Public Health degrees. She attended medical school in El Paso, Texas, at the Paul L. Foster School of Medicine, followed by an intern year at the University of California San Francisco, East Bay Surgery Residency Program in Oakland, California. She then moved to Oklahoma City, Oklahoma for residency training in Medical Genetics and Genomics at the University of Oklahoma Health Sciences Center. She now lives in Oklahoma City with her husband, daughter and two cats. She enjoys spending time with family and enjoying the outdoors.
Rebeca Venezia
Rebeca — who’s originally from Baja California, Mexico — earned her MSc in Nutrigenomics and Personalized Nutrition from the University of the Balearic Islands in Spain and her BSc in Biotechnology from the University of Wroclaw in Poland. She attended Sarah Lawrence College in New York to obtain a degree in genetic counseling because she was drawn to the clinical aspect of the genetic field. As a board-certified genetic counselor, she is dedicated to enhancing everyone’s access to high-quality genetic services and believes in the transformative power of learning about patients’ life stories.
Erin Ingraham
After spending the majority of life on the east coast and completing a BA in Psychology, Erin transplanted to Denver in 2018. She began focusing on healthcare administration in the dental field as a pediatric office manager for several years before transitioning to the medical field. Erin joined SequenceMD as our Clinic and Patient Coordinator in January of 2023 and strives to provide patients with an above and beyond experience as they navigate their diagnostic journey.
Erin Jahahn
Erin grew up in Colorado and received her Master’s in human genetics and genetic counseling at Keck Graduate Institute in Claremont, California. She attended the University of Oregon and graduated with undergraduate degrees in psychology and biology. She has a research background encompassing neuroscience and genetic engineering, and was a clinical research coordinator in neuroimmunology. As a genetic counselor, Erin specializes in cancer genetics, integrating her research experience with a patient-centered approach. She’s dedicated to providing her patients with personalized genetic insights and support, helping them navigate complex medical information and make informed decisions about their health and treatment options.
During Dr. Long’s Medical Genetics residency at the University of Colorado School of Medicine, he connected with a group of individuals focused on helping non-genetic clinicians identify genetic patients by using online diagnostic assessments. In collaboration with geneticists from University of British Columbia and University of Pittsburgh Medical Center, Dr. Long started to conceptualize how tools can be built, utilized, and integrated into a physicians’ practice workflow for the benefit of hastening the diagnostic journey for complex patients.
While Dr. Long completed his fellowship in Medical Biochemical Genetics at the Children’s Hospital of Colorado, he partnered with UnX, a management services organization focused on identifying rare disease patients while capturing the objective and subjective value of whole genome sequencing in adult patient populations. Together, they began developing clinical and non-clinical assessments, as part of a suite of decision support tools, to identify those patients who could benefit from genetic testing and to capture the value of genetic testing for these patients.
Utilizing the decision support tools developed with UnX, SequenceMD opened its doors in Denver, Colorado to patients with remarkable clinical presentations and their providers seeking diagnostic clarity.

Dr. Jessica Duis
Dr. Duis is a geneticist and special care provider who takes care of patients from birth through adulthood. She did her medical training at Johns Hopkins School of Medicine in Baltimore, MD. She completed a post-doctoral fellowship in the Johns Hopkins Department of Psychiatry and Behavioral Sciences. She is a board-certified pediatrician and medical geneticist who practices in genetics and complex/special care pediatrics and primarily performs diagnostic work up and management for individuals with rare disorders focused on neurogenetic conditions and rare genetic causes of obesity and metabolic conditions. She has focused her career on chromosome 15 disorders including Angelman Syndrome, Duplication 15q, and Prader-Willi syndrome. She has founded and built Centers of Excellence for Angelman, Prader-Willi, duplication 15q, CHD2- neurodevelopmental disabilities and Pitt Hopkins Syndromes. Jessica lives in Colorado with her husband and three kids and enjoys spending time with her family outdoors.
