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

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.


"I found Katherine Johnson when I posted in a FB group for Moms because I knew I needed Help but had NO idea where to start. As women age we experience so many changes and Katherine is the Nancy Drew of getting to the root cause! She’s so passionate about helping others and it shows! I’m so grateful for her and her team! And I’m all about supporting local business! Thanks for everything!"



"I love love Dr Johnson. She is amazing and makes you feel at ease. I want to make that clear! The reason that I did not give a 5 star is because of a certain staff member. When I was trying to explain my reasoning of not being able to come do a follow up....was told on the phone prior to first visit that they did take carecredit and gave a totally different copay amount, she got defensive saying how it's only 3 people blah blah blah and they don't take it. Ok. I get that. But if you let me talk and finish instead of getting defensive and interrupting. Yes, maybe the person misunderstood?? Idk, but it happened. You can say it never did but it won't change the fact that yes it did. I even showed them the number at the time of visit, which was theirs that I called hrs prior to confirm copay price when the receptionist tried to say I called a different office. I didn't make it up. But don't get ugly cause you think no one could have made a mistake on your end. Maybe she thought I said something else. Idk. Either way, I'm not mad about it. I wasn't even getting nasty on the phone. I just was telling what happened. Nothing more. So don't try to talk over me on the phone cause you don't agree and want to basically say I'm lying. I just chose this place because I heard great things about Dr Johnson, which is all true and thinking they did take it which unfortunately for me, they dont. But even the copay amount that I was told originally, ended up being twice as much as well."



"Katherine Johnson is an Angel. Caring, kind, and understanding. The office staff is courteous and professional. The office is clean and beautiful."



"I had my first consultation and procedure with Katherine and staff. The staff were professional from the time I was greeted at the door from the time I left Katherine’s office . I admire the professional, kindness and knowledge that was delivered to me from Katherine and staff.. I highly recommend this entity. I will definitely refer to this entity for future procedures and treatments. Thank you Katherine and staff .."



"Katherine and her staff are the best. Always responsive and friendly. Katherine really listens to your concerns and treats the individual and not an "out of the box" treatment that is the same for everyone. She is always on time. Takes the time to have the conversation WITH you and doesn't talk AT you. I was referred to her by friends, and I continue to recommend her to others."
