Your medical records will remain securely stored at South Denver Gastroenterology. If you choose to transfer your records to an outside provider, you may contact the office at 303-788-8888, and they will assist you with the process.
As I step into retirement, please know that I carry with me immense gratitude for the privilege of caring for you over the years. Thank you for your trust, your kindness, and the opportunity to serve you.
I wish you continued health and well-being.
Patient Care Philosophy
I believe listening carefully to each patient’s story sets the stage for excellent gastroenterology care. I favor shared decision making, taking into account each patient’s goals and preferences along with a thorough understanding of the current science of gastroenterology. In addition, I focus on providing personal and compassionate care.
