Jenks, OK

Dr. Jeffrey E. Chasteen is a highly experienced family medicine physician who has been providing compassionate, patient-centered care to the greater Tulsa metro for over two decades. A graduate of the OSU College of Osteopathic Medicine in 2000, Dr. Chasteen has maintained his board certification in Family Practice since 2003. His extensive background includes experience in family medicine, urgent care, hospice, and palliative care, making him well-equipped to address a wide range of healthcare needs for patients of all ages.

Dr. Chasteen’s decision to pursue medicine was driven by a desire to engage in a lifelong, intellectually stimulating career where he could make a direct impact on people’s lives. He thrives on the ongoing challenge that family medicine presents, especially the variability of cases and the deep relationships he builds with his patients. “The patient encounter itself is the thing I could never give up,” he says, reflecting on the honor of helping patients navigate their health challenges.

Dr. Chasteen believes in a collaborative approach to care, viewing himself as an advocate, interpreter, and guide for his patients. He empowers them to make informed decisions about their health while offering expert advice to help them choose the best path. This philosophy aligns perfectly with the Direct Primary Care (DPC) model, which allows him to deliver care without the restrictions of insurance-driven decision-making.

Dr. Chasteen believes his past experience in hospice and end-of-life care has given him a unique perspective on the importance of compassionate, holistic care, which he integrates into his family practice. As a family doctor he is honored to help individuals and families through all stages of life, from preventive care to managing chronic conditions.

Outside of work, Dr. Chasteen enjoys spending time with his wife, Mia, and is embracing his role as a grandparent following the arrival of his first grandchild, Margot. He is also an enthusiastic cook, channeling his former life as a short-order chef into his gourmet culinary endeavors. When he’s not in the kitchen, he can often be found indulging his passion for cars, boats, motorcycles, and other mechanical projects that may one day become part of his growing collection of “garage art.”

Dr. Chasteen is excited to be part of a practice that puts patients first and looks forward to providing the highest quality care to his community.

Dr. Corey Chamness radiates positive energy the moment she opens the door! She is most known for her ability to connect with patients and create long-lasting personal relationships. She is board-certified in family medicine and passionate about playing an active role in her patient’s overall health and well-being.

She grew up in a small town in Oklahoma where community was everything— her natural gifts and desire to help others led her to pursue a career in family medicine. She attended The University of Tulsa, where she graduated Magna Cum Laude with a B.S. in Biochemistry before earning her Doctorate of Osteopathic Medicine from Oklahoma State University College of Osteopathic Medicine. Dr. Chamness completed her family medicine residency at OSU Medical Center and directly out of training, joined St. John Clinic, where she served the Tulsa and Broken Arrow community for the first seven years of her career.

Dr. Chamness is most excited to join PHP because it will allow her patients to have more time and access to her – so she can focus on what is important to the patient, not to insurance companies. She believes in the direct primary care model because it embraces her approach to medicine by providing a laid-back and calm environment that enables her to really get to know her patients.  She enjoys taking care of the entire family and has a special interest in women’s health, medical weight loss, hormone replacement therapy, and testosterone therapy. 

When Dr. Chamness isn’t busy caring for patients, you can find her spending time with her husband and two children. She also enjoys traveling, online shopping, and being an active member of her church.
