The Green Country Endodontics Team

We really eat, live and breathe endodontics and taking care of our patients. We can only do this as part of a well orchestrated team where everyone knows their role. Amy Johnson-Rener runs the front office, meeting and greeting patients and handling billing. Dr. Johnson is the clinician performing compassionate root canal treatment.


All team members at Green Country Endodontics have combined their years of caring for patients in pain and made a commitment to excellence and personal care and compassion for each and every patient.

From the minute you schedule your appointment with Amy, through the care you receive from her assistant and the treatment Dr. Johnson provides, the team at Green Country Endodontics wants to know you are in good hands.

Our mission is to provide the highest quality, compassionate care in a peaceful, state-of-the-art environment. It is our unconditional philosophy to provide individualized treatment.

We strive to be the best endodontic office and bring our years of experience and diversity to provide Tulsans with the care they deserve.

Amy Johnson-Rener / Front Office Coordinator


Amy was raised in Tulsa and graduated from Jenks High School. Endodontics run in her blood; being the daughter of retired endodontist, Dr. Wm Ben Johnson. Amy has been involved in endodontics since she first worked for her father in Jr High. She started working at Green Country Endodontics as an insurance coordinator in 2014 and now she is our front office super star. Amy communicates with our patients, coordinates their treatment, and explores financial options available to them. She also communicates with our referring dentists and their staff so that we are providing the best experience for each patient. 

In her spare time, Amy enjoys being outdoors in the sunshine. She is the mother of three amazing kiddoes ages 14, 21, and 29. 

With the ability to provide sedation dentistry to the most fearful patient, nervousness should not interfere with getting your dental needs to complete health. From IV sedation to general anesthesia, we can perform our work in the same office you have come to trust and where you expect quiet compassionate care.

Ask Dr. Johnson or Amy about sedation dentistry and whether you are a good candidate for the treatment.

“Green Country Endodontics is very caring, gentle and their attention to detail is paramount. Dr. Eugenia Johnson and staff are amazing. Total care and extremely satisfied. Dr. Eugenia Johnson and staff take pride in their work and I couldn’t ask for better care.”


“Just so happy Dr. Johnson could save my tooth. I really didn’t want it pulled for an implant.”



“Was I lucky to be seen by Dr. Johnson or what? My dentist recently crowned a tooth and I had major pain for the next 3 days and he wasn’t working on Friday. A friend recommended Dr. Johnson and I was seen that same day as an emergency. I was so comfortable when I was being treated I actually dozed off. The folks at this office are so compassionate and caring. I will recommend Dr. Johnson to any friend who needs a root canal.”
