Four physicians join Providence Medical Group


Four new physicians will join Providence Medical Group in August, according to Kathleen Obenland, director of public relations.

Dr. Jennifer Leach, specializing in the treatment of kidney disorders, doubles the nephrologist staff at Providence St. Mary Medical Center, allowing patients with kidney issues to get appointments more quickly.

Leach received her medical degree from Duke University School of Medicine in North Carolina. She performed her residency and fellowship at Oregon Health & Science University in Portland. She comes to Walla Walla from Portland. She is married to Dr. Benjamin Leach, who also is joining St. Mary.

Benjamin Leach is a hospitalist, a physician who focuses exclusively on the care of patients in the hospital. He received his medical degree at the University of Texas Southwestern Medical Center, and performed his residency at Oregon Health & Science University.

Radiation oncologist Dr. Spencer Ashton specializes in the treatment of cancer with radiation. He will be practicing in the Providence St. Mary Regional Cancer Center. The center provides all aspects of cancer diagnosis, treatment and patient support. Among other things, Ashton's practice will expand local treatment options for prostate cancer patients, according to Obenland.

He received his doctorate from the University of Virginia School of Medicine and served his radiation oncology residency at the State University of New York.

A general surgeon with a decade of experience, Dr. Daniel Sparks, joins St. Mary after a practice at Wenatchee Valley Medical Center, where he also served from 2003 to 2007 as the medical director of trauma. Prior to Wenatchee he practiced with the Group Health Cooperative in Seattle.

Sparks received his medical degree from George Washington Medical Center in Washington, D.C., and performed his internship at the University of California Los Angeles Medical Center in Los Angeles and residency at Swedish Medical Center in Seattle. He is board certified by the American Board of Surgery and holds Advanced Trauma Life Support certification.
