Satinder Gill, MD, CSL founding physician, added, “We are excited to partner with One GI to help us continue to improve the well-being of our patients and expand our commitment to meeting the growing need for GI and liver healthcare in Loudoun County and our neighboring communities.  We are honored to spearhead and share One GI’s mission here in Virginia.”
