Meet Katherine

PractitionerA proud graduate of Texas Woman's University, Dallas, Katherine Johnson feels privileged to care for her patients. She is skilled in treating multiple chronic medical conditions, acute illnesses, and also helping patients achieve their wellness goals in a truly individualized and compassionate manner. Before becoming both an oncology nurse and a family nurse practitioner (FNP), Katherine graduated from Oklahoma State University in 2010, earning a degree in nutrition with an emphasis in dietetics. Her combined classroom instruction and clinical experience over seven years allowed her to become well-versed in helping patients heal from their multiple chronic conditions, including weight gain, from a biologic and metabolic perspective.

Experience and Certifications

Through her experience within both internal medicine and family medicine, Katherine became passionate about her pursuit of helping those seeking wellness, weight loss, and chronic care management solutions different from other clinics; thus, Johnson Family Medical came to be. She is a board-certified family nurse practitioner through the American Academy of Nurse Practitioners and is a member of the Texas Nurse Practitioners. Katherine is also a founding member of NP Axxess, the only Independent Practice Association for nurse practitioners in Texas.

Personal Interests

Beyond her passion for caring for her patients, Katherine is also a family-oriented wife and mother, a daughter to her loving parents, and a sister to her wonderful brother and sister-in-law. She enjoys reading, is an avid sports fan, and also enjoys traveling. Katherine grew up in Frisco, TX and appreciates the "smallest big town" culture that Frisco offers today.


"My experience has been Exceptional!!! Listen, if you seriously need a PCP that actually cares, listens and offer the best solutions, then JFM is where you belong. Katherine blew me awayyyy, just by the fact that she actually CARES about her patients on another level. Her staffs are phenomenal, so warm and so kind. I recommend her to everyone I meet! Extremely happy to have her in my life now."



"I absolutely Love Dr. Johnson, Alma and Ledi. Great office personnel and you won’t find a more caring Doctor anywhere in Texas. They have helped me through tough health situations. I am forever grateful and appreciative! My husband loves them too!"



"What a wonderful experience I had at Johnson Family Medical. Katherine not only took the time to discuss my treatment options and plan but her compassion and professionalism was exceptional. I would highly recommend her to everyone. Her staff as well is friendly, kind and accommodating. The experience I had here far exceeds experiences I have had in other primary care offices where you are just a number.... and this is coming from a fellow RN."



"Katherine and her staff is amazing. She treats you as a patient with total concern and care. You do not feel like just a number being called for a check up as some PCP's make you feel. I'm so glad that I found JFM and I highly recommend them. 🥰"



"The staff was pleasant and made me feel welcomed during my first visit to Johnson Family Medical. Katherine was personable, thorough in her questions and exam, and made me feel comfortable discussing my medical background and current issue. ... and my blood draw didn't hurt!"
