What Dr. Beck loves most about practicing medicine is getting to know each patient’s unique story. She values the opportunity to partner with individuals and families on their path to wellness, celebrating their milestones and helping them achieve health goals based on what matters most to them. She also appreciates the ever-changing nature of medicine and the learning that comes with every patient encounter. She is also bilingual in Spanish, which enhances her ability to care for diverse patient populations. Originally from Eudora, Kansas, Dr. Beck chose to stay in-state to give back to the place that played such a key role in her education and training. She now lives in Mayetta with her husband, four children, and their Husky, Tiggr.
