Fredericksburg Providers

My calling is to “make a difference” in the lives of others. My passion is to serve others and use my talents to provide an individualized approach to the care of the patient while remaining committed to quality, honest medical care.

I was born in Germany, where my father served as an internist in the US Army. Growing up as the middle child of 5, family has always been the center of my life. My grandparents were my greatest role models. They instilled in me the values of service, commitment, compassion, kindness, a strong work ethic, and humility. My mother taught me how to be a mom. We grew up baking, sewing, gardening, and above all sharing. My father taught me to work hard but always balance work and home. Travel was an important part of our upbringing as was enjoying daily ‘coffee’ with baked goodies and lots of family fellowship.

Upon graduating Valedictorian from Killeen Ellison High School, I studied biomedical science at Texas A&M University graduating Summa Cum Laude. My original plan was to enter Veterinarian School, but took a sabbatical to further explore my calling. During that time, I came to realize that while I absolutely loved animals and the science of veterinarian medicine, my professional and spiritual calling was to serve people more directly. To this day, I continue to have my own personal ‘brood’ of pets, and have the best of both worlds. I completed medical school at UT Southwestern in Dallas and a residency at Tacoma Family Medicine in Washington where I was able to train in broad spectrum Family Medicine with care of the entire family including obstetrical care. I married my best friend, Mark during medical school and we have been blessed with four children and the opportunity to raise them in Fredericksburg.

Family medicine offers me the opportunity to use my education while directly serving patients from newborns to elderly and everyone in between. Every day I strive to provide the best possible medical care to each patient I see. The doctors at Cornerstone Clinic are truly the best- wonderful, caring, inspiring physicians. The small, close knit community, excellent schools, and our loving church home have provided a great place to raise our family. Personal time for me is mostly family time and I do find bits of time for cycling, reading, and playing outdoors. I continue to practice full spectrum family medicine with obstetrical care, newborn and well child care, preventative adult medicine as well as care of the chronically ill and hospitalized. My primary approach to the patient is to avoid ‘textbook medicine’ and instead provide individualized care with solid scientific grounds

My calling is to serve patients with compassion and kindness while meeting their medical needs.

Core Principles/Values:
I value getting to enjoy the patient-physician relationships that are developed with my patients by learning as much about them as I can, medically, but also by learning about their occupations, family members, and interests; thus, allowing me to make a difference in their whole lives. I enjoy the diversity of caring for and treating patients of all ages.

My background includes growing up in Hillsboro, TX, obtaining undergraduate and medical school degrees at Texas A&M University, and completing training in family practice residency in
Waco, TX. I have also had the opportunity to go on several foreign medical mission trips. My wife, Angie, and I have been married for 30+ years, and we have five children and two grandchildren. I love spending time with my wife, kids, and grandchildren. I also enjoy serving in our church in its various ministries. Other interests of mine include sports, bow-hunting, camping, and ranching.

Drs. John Ramsay and Suzanne Ellison Ramsay founded the Cornerstone Clinic in 1991. They were married in 1980 and began practicing in Fredericksburg in 1984.

Dr. Ramsay loves and practices the whole range of Family Medicine. Following the completion of college at Vanderbilt University and Medical School at Southwestern in Dallas he pursued a Family Medicine Residency in Tallahassee, Florida followed by an Obstetric Fellowship. This emphasis in delivering babies led him to help bring over 2,500 babies into this world spread throughout the Hill Country. Caring not just for the babies and the mothers but the fathers, aunts, uncles, and grandparents gives him great pleasure. Indeed over half of his practice is devoted to seniors many of whom he has known for over 25 years. His patients know him as a great story listener and teller. They were as excited as he was in his selection as the Texas Family Physician of Year in 2008.

Outside of Medicine his interests include five grown children, many grandchildren, the Classical Christian Heritage School where he was a founding trustee, serving at the Hill Country Church, running Marathons especially with his children, raising pecan trees, and beekeeping.

After completing my medical training, I relocated to Fredericksburg and joined Cornerstone Clinic in 2000. I am originally from San Antonio, TX. I attended Texas A&M University and earned an undergraduate degree in Biochemistry. Following my undergraduate studies, I attended UT Houston Medical School and completed a Family Medicine Residency in Waco, TX. I then completed an Obstetric Fellowship at Brackenridge Hospital in Austin, TX.

I am honored to use my knowledge and gifts to help in the promotion of wellness and the healing of illness in patients of all ages. My greatest joy is to care for the families I serve. As a family physician in Fredericksburg, I have the ability and privilege to care for multiple generations of families. Delivering babies, preventive medicine, outpatient care of chronic medical problems, and nursing home care are all facets of my practice. The connection to each person and the relationships built with families is the joy of my practice.

I met my husband, Adam, in Fredericksburg. We have been blessed by three beautiful girls, who keep us busy with all types of activities. My husband and I also have large extended families, and we enjoy spending family time together. I volunteer for various organizations, and worship God with my family at Fredericksburg United Methodist Church.

When my family and I moved to Fredericksburg in 2009, I knew we had found home. I am honored to be able to serve the people of Fredericksburg and the surrounding communities through my role as a Family Nurse Practitioner at Cornerstone Clinic. As a nurse practitioner, I am able to meet your comprehensive healthcare needs including providing prescriptions, offering wellness and preventative services, ordering and interpreting laboratory tests and radiology studies, and making referrals as needed for specialty care.

I received my bachelor’s of science in nursing from the University of Pennsylvania. After graduation, I was commissioned as an officer in the United States Navy Nurse Corps and served for six years. I was blessed to care for our nation’s service members, their families, and veterans in places as far away as Guam and the Persian Gulf.

After fifteen years of bedside nursing, I decided to return to school so I could more thoroughly meet the needs of my patients. I graduated from Texas Tech Health Sciences Center with my master’s of science in nursing and received the Excellence in Nursing Award, awarded by the faculty to the top graduate each year.

In May 2018, I received my Doctor of Nursing Practice degree from University of Texas Health Sciences Center San Antonio, where my research focused on suicide prevention by identifying and helping people experiencing spiritual distress. I’ve presented my research at two conferences, including the 2019 Sigma Theta Tau Biennial Convention. Although I do enjoy research and the academic setting, my heart remains in primary care.

My passion as a nurse practitioner is optimizing each person’s health and wellness. I enjoy caring for infants and taking the time to talk to new parents’ concerns as much as I love helping elderly patients stay happy, healthy and independent and everything in between. My intent is to partner with each patient to establish a realistic plan of care to meet individualized health goals.

Outside of work, I enjoy spending time with my husband and our three children and serving in the community.

Comfort Providers

Dr. Rickerhauser grew up in Lancaster, Pennsylvania and completed her undergraduate degree in pre-med at Eastern Mennonite College in Harrisonburg, Virginia in 1987. A desire to provide compassionate care and truly make a difference carried her through medical school at Temple University in Philadelphia, Family Practice Residency at Lancaster General Hospital and an Obstetrics fellowship at Harrisburg Hospital, all in Pennsylvania.

In 1996 Dr. Rickerhauser moved to Texas to join the faculty of a new Family Practice Residency
Program at Valley Baptist Medical Center in Harlingen where she taught for 12 years. During that time she married her husband Ron; their daughter Jenna joined them a few years later. Participating in the lives and training of young doctors who now practice medicine around the globe was a rare privilege.

Dr. Rickerhauser and her family moved to the Hill Country to join Cornerstone Clinic in 2008 and since then she has worked full-time at our Comfort office, providing full-spectrum care for all ages, including obstetrics. Outside of medicine, she enjoys playing violin and piano, participating in community theater, traveling and spending time with her family and their many animals. Her husband Ron is a licensed professional counselor who sees clients in Fredericksburg and her daughter Jenna is studying music at Abilene Christian University.

Dr. Rickerhauser enjoys the variety found in family medicine and believes that each day is a new adventure. Her goal is to provide excellent medical care with a personal touch to assist her patients to achieve true wellness; not just the absence of disease, but a healthy body, mind and soul, so they can reach their God-given potential. “My purpose is to know and share hope and encouragement with those God brings into my path each day.”

I love what I do!  I started late after all my children were in school. I have 3 sons and 1 daughter.  I went to UTHSCSA for my nursing degree and Texas Tech for my master’s degree. I spend my free time gardening and taking care of my dogs, cats, and horses. I previously lived in Boerne for 21 years and have lived in Comfort for 4 years.
