M. Celeste McKean, MS, APRN, FNP-C

Celeste grew up in Kansas and took an educational journey before eventually finding her calling as a Family Nurse Practitioner.  While working in laboratory sciences in endocrinology, general lab, and microbiology, the faceless lab tests awakened an interest in meeting and supporting patients face to face, so she enrolled in nursing school.  She discovered a passion for caring for and educating people while working in stroke, trauma, and ICU. This passion grew from not only caring for them at their worst, but helping them reach their best health, so she pursued her Family Nurse Practitioner degree.

She has been married to her husband, Brian, for 20 years.  They have a daughter and son, both in high school.  She adores watching her children at swim meets, softball games, and theatre events.

She loves to cook and try new foods, traveling around the world with her family, participating in mission trips, having lunch with friends, and going to the movies.  She enjoys reading books about women in the WWII era, and following Star Wars and Marvel.

She enjoys helping people live life to the fullest and is excited to educate her patients on how to pursue optimal health at Southlake Integrative Wellness Center.

Alison Wensrich, MS, PA-C, HHC, AFMCP

Alison Wensrich is a board-certified Physician Assistant with over 20 years of experience across family medicine, oncology, and functional medicine. She holds certifications from the Institute for Integrative Nutrition and the Institute for Functional Medicine (AFMCP), blending a strong foundation in traditional medicine with a personalized, root-cause approach to healing.

 Alison’s passion for functional medicine is deeply personal. Diagnosed with cancer at age 20, she was inspired to pursue a career in healthcare. A decade later, facing anxiety and autoimmune thyroid issues, she turned to functional medicine to search for answers. Through restoring her gut health and addressing the underlying causes of her symptoms, she experienced firsthand the power of integrative healing—and has been committed to helping others do the same ever since.

 She is especially passionate about supporting individuals with gut health issues, including IBS (Irritable Bowel Syndrome) and IBD (Inflammatory Bowel Disease). Currently pursuing a specialized certification in the integrative and functional approach to IBD, Alison brings both clinical expertise and a deep sense of empathy to her work. She understands how overwhelming a diagnosis can be, and she’s dedicated to empowering patients through education, personalized care, and lifestyle-based strategies to improve symptoms and long-term outcomes.

 Outside the clinic, Alison is a wife and proud mother of two. She enjoys traveling with her family, cooking nourishing meals at home, walking with her two doodle dogs, and keeping up with her kids’ busy schedules—including percussion, scouts, cross country, gymnastics, soccer, and choir.

Kim Williamson, MMS, PA-C, HHC, AFMCP

Kim Williamson is a Board-Certified Physician Assistant with over two decades of experience in the medical field.  She is additionally trained and certified in both Functional Medicine and Holistic Health.  Her journey into integrative care began more than a dozen years ago when she was diagnosed with an autoimmune disease—an experience that reshaped both her personal health and professional path.

 Having battled a brain tumor, miscarriages, and a range of chronic health challenges—including hormonal imbalances, fatigue, digestive disorders, infections, and unexplained symptoms—Kim understands firsthand the frustration of being told “everything looks normal” while still feeling unwell.  After years of searching for answers without relief, she turned to her own research, study, and training in integrative and functional medicine.  By uncovering the root causes of her conditions, Kim was able to restore her own health—and now helps others do the same.

 Beyond her work, Kim is a wife and mother of three.  She loves spending time with family and friends, traveling, experiencing new cultures and cuisines, exploring nature, and capturing life’s moments through photography.
