 Tammy Chavarria, RN, APN

Tammy Chavarria RN APN Building Trust and Sharing Values 
"I find it a tremendous strength and have enjoyed participating in the care of women through a wide range of areas surrounding reproductive health. I have educational training not only in infertility, but also with gynecology, obstetrics and genetic counseling. My experience and education in advanced practice nursing includes a background as both a clinical nurse specialist and a nurse practitioner. It has enabled me to provide excellent patient care, and also to share with our patients my significant dedication and commitment to counsel and educate patients regarding their personal health care."

  • Nurse Practitioner Certification; Drexel University, Philadelphia, PA,
  • Master of Science in Nursing with Specialization in Women's Health and Genetics; Rush University, Chicago, IL
  • Bachelor of Science in Nursing, North Park University, Chicago, IL
  • National Certification as a Women's Health Nurse Practitioner by the National Certification Corporation
Nursing Experience With Ethics & Pride
Tammy's extensive education and commitment to providing outstanding health care brings a new facet of patient care to our practice she excels in not only caring for patients, but also educates and mentors the ARHC clinical team. Working side-by-side with the physicians, as well as independently meeting with patients in their treatment, allows continuity of care with a very personal interaction throughout each patient's experience.

A "Golden Rule" Philosophy
"The most important commitment a health care provider can make, outside of maintaining a current knowledge base, is to remember to always treat others as we would want to be treated. I value integrity and respect of individual concerns, and I wholeheartedly appreciate accessibility to my patient's health care providers to maintain extensive open communication in their continuing care."

"Although I have never experienced the difficulty of becoming pregnant, I have endured my own sense of reproductive failure through recurrent pregnancy loss/fetal abnormalities. I deeply empathize with the emotional issues and sense of loss that surrounds desiring a child but struggling to conceive and carry."
