Timothy E. Phelan, M.D. F.A.C.O.G.


Originally from Oregon, Dr. Timothy E. Phelan, has studied and worked all over the U.S. in order to learn how to provide exceptional healthcare for women.  After graduating cum laude from the University of Rochester in New York with a B.A. in   Biology, he returned to Oregon and received his medical degree from the Oregon Health Sciences University.  During   medical school he saw his first delivery and from that moment knew he wanted to be an obstetrician.  Knowing that skilled   doctors require vast amounts of experience he sought out a residency program that was famous for its large number of   patients. After a year of internship at the renowned Charity Hospital in New Orleans, he completed his residency in   obstetrics and gynecology at Louisiana State University School of Medicine in New Orleans.  Moving to Northern California in 1999 he established his own private practice, Creekside OB/GYN of Folsom, to provide exceptional and compassionate care to women from adolescence to menopause. To maintain his skills Dr. Phelan is a diplomat of the American Board of Obstetrics and Gynecology and a Fellow of the American College of Obstetricians and Gynecologists.  He delivers and operates at Mercy Hospital of Folsom where he has served as chair of the OB/GYN Department, the Physicians Performance and Improvement Committee and the Interdisciplinary Committee.  As a da Vinci trained laparoscopic surgeon he has the distinction of being the first surgeon at Mercy Hospital of Folsom to perform a da Vinci robotic surgery. Dr. Phelan enjoys spending time with his wife and three daughters.  In his free time he challenges himself by running ultra-marathons.

Shanley Schoenhofer, RD | Creekside OB/GYN

Shanley Schoenhofer, RD

A native of Humboldt County, California, Shanley Schoenhofer’s passion for nutrition was set alight after surviving a nutritional illness as a teenager.  After getting her B.S. in Nutrition and Food Science from California State University Chico she began working for a nonprofit organization in Santa Rosa as a nutrition program coordinator.  Falling in love with her work, she found she especially enjoyed working directly with patients, so she sought out further education and training. Soon after becoming a Certified Lactation Educator she completed the rigorous and highly competitive registered dietician program at California State University Sacramento. Now as the director of the Perinatal Nutrition Program at Creekside Ob/Gyn of Folsom Shanley gets to work directly with women before, during and after their pregnancies.


“I have always wanted to be involved with preventative nutrition,” Shanley says, “and I can’t think of a better place to implement preventative nutrition than at the beginning of life.” She adds,” This is an incredible time to help women form dietary habits that can hugely affect their health and the health of their children.”  In her free time, Shanley enjoys any form of exercise, spending time with her family and reading.
