Emma Beck, MD
Dr. Emma Beck earned her Bachelor of Science in Biology with a Minor in Spanish from Oklahoma Baptist University. She went on to complete her medical degree at the University of Kansas Medical School, followed by residency training at Via Christi Family Medicine, where she also completed the Osteopathic Recognition Track. She is currently eligible to sit for the Family Medicine-Obstetrics boards. Dr. Beck’s clinical interests include women’s health and obstetrics, international medicine, and point-of-care ultrasound. Her passion for medicine was sparked early in life, inspired by her mother’s example as a dedicated veterinarian serving their local community. That calling grew into a desire to serve vulnerable and underserved populations—both in rural areas and abroad—with a human-focused, hands-on approach (minus the paws). 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, Tigr. When not at work, you’ll likely find her outside—playing sports, taking walks, working in the yard, or relaxing in her hammock. She’s excited to be living closer to family and looks forward to many backyard gatherings and outdoor adventures. There may even be chickens in their future!

Collin Connor, MD
Dr. Collin Connor didn’t always dream of becoming a doctor — but a year of service through AmeriCorps changed everything. While volunteering at a free medical clinic in Providence, Rhode Island, he discovered how deeply his strengths in listening, teamwork, and problem-solving could serve others through medicine. “That experience helped me realize I could combine my love for science and learning with my desire to help people,” he said. “It truly felt like a calling from God — everything just fell into place.” A native Kansan, Dr. Connor earned his biochemistry degree from Emporia State University, then went on to study at the University of Kansas Medical Center. He completed his family medicine residency at Ascension Via Christi in Wichita. Dr. Connor enjoys caring for patients of all ages and building long-term, trusted relationships with the families he serves. Outside of work, he stays active with his wife and three sons, listens to music and podcasts, plays or watches just about any sport, and spends time in the garden. He’s also looking forward to exploring more of the great outdoors — starting with an elk hunting trip next year. Dr. Connor and his family are excited to call Onaga home and are proud to be part of the CHCS community.

She and her husband, Paul, are recent empty-nesters and enjoy traveling when they can.
