Embryology Staff

The embryology and andrology laboratory at RCC has the highest possible accreditation in the United States, by the College of American Pathologists (CAP), since 2001 and continues to maintain certification through CAP administered inspections and proficiency testing. Since 2001, the laboratory has maintained a Certificate of Compliance with the Clinical Laboratory Improvement Amendments of 1988 (CLIA). CLIA was formed by Congress to establish quality standards for all laboratory testing to ensure the accuracy, reliability and timeliness of patient test results.

The laboratory is part of the Society of Assisted Reproductive Technology (SART). SART was established by member IVF clinics to set and maintain standards for assisted reproductive technology centers. This was done in an effort to better serve members and their patients. One of the key functions of SART is to help patients view national and individual clinic IVF success rates. Our success rates have been reported to SART since 1998.

Brett Reggio, PhD, HCLD

Lab Director

Dr Reggio graduated from Tulane University in New Orleans with a BS in Biology in 1992, and then moved to Baton Rouge to pursue his MS (1997) and PhD (2002) degrees at Louisiana State University (LSU) in the Department of Animal Science. While at LSU, he concentrated on in vitro embryo culture systems and in producing cloned transgenic dairy animals capable of generating valuable pharmaceutical proteins in their milk, working closely with Genzyme Transgenics Corporation Biotherapeutics. One of these therapeutics (ATryn) was approved in August 2006 by the European Commission for use in patients with hereditary antithrombin deficiency undergoing surgical procedures. This was the first approval in the world of a therapeutic protein produced from a transgenic animal. In 2009, ATryn made history by becoming the first biological product produced by genetically engineered animals to be granted FDA approval in the United States.
After leaving LSU in 2003, Dr. Reggio moved to Washington, DC to join the IVF team at Walter Reed Army Medical Center in order to use his skills in a clinical IVF setting. In 2005, He became the IVF Laboratory Supervisor at the Northern California Fertility Medical Center in Roseville, California. He was then recruited to join the Reproductive Care Center in February 2007 as the Director of Research and Development.

Dr. Reggio completed his High Complexity Clinical Laboratory Director (HCLD) certification through the American Board of Bioanalysis (ABB) and became the Reproductive Care Center laboratory director in August 2008. Dr. Reggio is also a member of the College of Reproductive Biology (CRB) administered through the American Association of Bioanalysts’ (AAB). He is a member of the American Society of Reproductive Medicine (ASRM) and the European Society of Human Reproductive and Embryology (ESHRE).

Benjamin Sessions, PhD, HCLD, ELD, TS

Lab Director – Idaho IVF Center Lab Director

Benjamin R Sessions, PhD, HCLD/ELD/TS, is the Scientific Director of RCC and the Idaho IVF Center Laboratory Director.  Dr. Sessions earned his BS in Biology and Chemistry in 1999, and obtained his MS (2004) and PhD (2012) in Animal Science from Utah State University.  After completion of his PhD, Dr. Sessions worked as a Research Assistant Professor in the Department of Animal, Dairy, and Veterinary Sciences at Utah State University where he taught laboratory based biotechnology courses for both undergraduate and graduate students in addition to being a member of the USU somatic cell nuclear transfer team where he assisted in producing clones of cattle, sheep, goats, and mules.

While at USU he gained extensive experience performing oocyte aspiration and maturation, in vitro fertilization, in vitro embryo culture, and embryo cryopreservation in the bovine model. He has published numerous abstracts and scientific papers and presented his research findings at many national and international scientific conferences. Dr. Sessions’ research focused on improving the embryo culture conditions of bovine nuclear transfer and IVF embryos as well as elucidating the key signaling pathways involved in oocyte activation and characterizing the epigenetic reprogramming profiles of key genes required for proper bovine embryonic development.

Dr. Sessions desired to use his knowledge and experience to assist patients in obtaining their dreams of having a family and as a result joined RCC in 2014. He is a member of the American Society of Reproductive Medicine (ASRM), and the European Society of Human Reproductive and Embryology (ESHRE), and is also a member of the College of Reproductive Biology (CRB) administered through the American Association of Bioanalysts’ (AAB).  Dr. Sessions helped design and establish the Idaho IVF lab in 2016 and has provided the embryology and andrology support for the Idaho IVF batches.

Sasha Hennessy Reggio, BS, TS

Senior Embryologist

Sasha Hennessy Reggio is the Senior Embryologist at RCC, and has been practicing embryology since 1993. She earned her BS degree in Biology from George Mason University in 1994, and was employed with Genetics and IVF Institute in Fairfax, VA for 7 years, working as a certified cytogeneticist and embryologist.

In 2000, Sasha joined The A.R.T. Institute of Washington, Inc. at Walter Reed National Military Medical Center in Bethesda, MD (formally known as Walter Reed Army Medical Center in Washington, DC), and was promoted to Senior Embryologist. During her 13 years at Walter Reed, she was responsible for maintaining the day-to-day operations of this busy IVF unit, and facilitated the training of fellows from the Combined Federal Fellowship in Reproductive Endocrinology and Infertility during their rotation through the IVF clinic.

In 2013, Sasha was recruited by RCC to join the IVF team as Senior Embryologist. She is a certified Technical Supervisor (TS) in Embryology, which is administered by the American Board of Bioanalysts (ABB). She also upholds her certification in cytogenetics with the American Society of Clinical Pathologists (ASCP), and is a member of the College of Reproductive Biology (CRB) administered through the American Association of Bioanalysts’ (AAB), European Society of Human Reproduction and Embryology (ESHRE), and the American Society of Reproductive Medicine (ASRM).

Douglass Brown, MS


Doug Brown is an embryologist at RCC. He obtained his BS degree in biology from Brigham Young University, where as an undergraduate, Doug helped to research and develop genetic markers for the South American lizard genus, Liolaemus. He also published work on the evolution and population genetics of North American Xenodontid Snakes.

Following his graduation in 2012, he began work on a MS degree in genetics and biotechnology, also at BYU. For his thesis, Doug focused on sequencing and characterizing starch biosynthesis genes in plant family Chenopodium, which includes the South American crop, quinoa. He graduated at the top of his program in the summer of 2014.

Doug has been employed at RCC since the fall of 2014 when he was brought on to work in the Andrology and Endocrinology Lab in the RCC Clearfield office. While in Clearfield, Doug was responsible for the day to day operations of lab, which included performing semen analyses, sperm preparations for IUI, and blood hormone assays. Doug was recruited to join the embryology lab in 2016.
