Meet Our Veterinarians

Dr. Mary Williams


Originally from Alberta, Canada, Mary was born in Edmonton and moved to Lethbridge with her family when her father took a faculty position at the University of Lethbridge. She graduated from high school in 2008 and began her undergraduate education at the University of Lethbridge. She then transferred to the University of Saskatchewan in Saskatoon where she completed her pre-veterinary requirements and graduated with a B.S. in Biology in 2012.

Mary began her journey in veterinary medicine at Ross University on the Caribbean island of St. Kitts. After completing the pre-clinical courses on the island, she finished her last year of veterinary school at Oklahoma State University in Stillwater and graduated in May, 2017.

Mary enjoys the variety and excitement that veterinary medicine involves. Every case is a new puzzle to be solved and she is enthusiastic about continuing to learn and grow as a new doctor. She has always had a passion for animals ranging from dogs and cats to horses. She grew up riding horses and is hoping to pick up that hobby again now that she has finished school. Right now she shares her home in Bartlesville with one dog, a yellow lab named Hammer who is a retired duck hunting dog.

Dr. Merrijean Becker


Dr. Becker is a lifelong Bartlesville girl.  Though her father worked in the International division of Phillips Petroleum Company, and she spent many of her early years in São Paulo, Brazil, and Caracas, Venezuela, her family moved back to Bartlesville when she was in 9th grade and she has always considered Bartlesville her home.

When Merrijean turned 16 she joined the Bartlesville Animal Hospital staff, working after school, summers and holidays, as a veterinary assistant for Dr. Grogan.  After graduating from Bartlesville High School in 1988, Dr. Becker attended Oklahoma State University where she completed her degree in Biomedical Science in 1992.  With glowing recommendations from both Dr. Grogan and Dr. Johnson, Dr. Becker continued her education with OSU, earning a coveted spot in their School of Veterinary Medicine.  In 1996, she graduated in the top 10% of her class earning her Doctor of Veterinary Medicine degree.  Throughout all her years at college, she made the commute back to Bartlesville to work summers and weekends at Bartlesville Animal Hospital. 

After graduation, Dr. Becker married a fellow classmate and began her career in Tulsa.  In conjunction with practicing medicine, she took on the role of Channel 8 Veterinarian for KTUL and was the “on air” veterinary expert in TV segments with Teri Bowers and Frank Mitchell.  In 2005, she was named “Young Veterinarian of the Year” by the Oklahoma Veterinary Medical Association.  While working full time and raising two small children, Dr. Becker pursued 10 years of additional study and in 2007 attained Board Certification with the American Board of Veterinary Practitioners. She is currently working on recertification.  Additionally, she was an active member of the Tulsa SE Rotary Club and dedicated to giving back to her community.

After inheriting her childhood home, Dr. Becker returned to Bartlesville and assumed the role of Manager for the Bartlesville Boarding Kennel.  She waited a year and a half for a position as a Veterinarian to become available here at Bartlesville Animal Hospital, and on January 1, 2018 Dr. Becker’s career came full circle back to where her dreams began…at her “Home”.

Dr. Becker has a passion for difficult medical cases, especially in geriatric pets and we could not be happier that she has joined our outstanding team of Veterinarians.

Dr.  Jeffery A.  Williams


Jeff Williams grew up on a small ranch in southeastern Oklahoma which allowed him the unique opportunity to be involved with animals for most of his life.

Beginning at the age of seven, he has been an avid participant in the sport of team roping.  He enjoys training horses and seeing the development from a green broke colt to a horse that can compete on a winning level. He enjoys the competition, excitement, friendships, and atmosphere that surrounds rodeo and team roping.   A coveted invitation to participate in the World Series of Team Roping in Las Vegas Nevada was extended to Dr. Williams in both 2017 and 2018.  Along with this sport, he also enjoys leather tooling, woodworking, fishing, hunting, playing basketball, and spending time with family and friends.

Upon graduating high school in McAlester, Oklahoma, Jeff decided to pursue his childhood dreams of becoming a veterinarian.  He selected Oklahoma State University and began the process of obtaining his Bachelor of Animal Science degree with an emphasis in Pre-Veterinary medicine. During his undergraduate years, he was a two-time recipient of the Wentz Research Award, which is one of the most prestigious scholarships available at OSU for student leaders who have engaged in campus and community service.  He continued his postgraduate work in Stillwater, achieving his Doctor of Veterinary Medicine degree in May of 2017.

Along with his skills in wellness, internal medicine, small animal soft tissue, and orthopedic surgeries, Dr. Williams is also certified with the American Veterinary Chiropractic Association and is skilled in both small and large animal chiropractic services.

Before joining our staff in September 2018, Dr. Williams remarked that he is “humbled daily to know that [he] is involved in a profession that as a group contains honest and truly caring individuals, and [he is] proud to identify with those same people that [he] has looked up to throughout [his] childhood”. He wanted “to be a part of a soundly managed practice that harbors and supports positive and hard-working people that have the client’s as well as the patient’s best interests in mind”; this desire has lead him to proudly be a part of the Bartlesville Animal Hospital staff.
