Dr. Kristin Martin, DO MS, FAAFP

Dr. Kristin Martin is an Oklahoma native and attended Southwestern College in Winfield, Kansas.  There she graduated with three undergraduate degrees: Bachelor of Science in Biology, Bachelor of Arts – Music, Piano Performance and Bachelor of Philosophy in International Studies.  She later would attend Oklahoma State University – Center for Health Sciences to complete a Master of Biomedical Science with an emphasis in Neuropharmacology (Opioid receptor research).  She performed research in a National Institutes of Health (NIH) supported lab focused on pain receptors and published several articles on the subject area. During that same time, she also attended OSU-College of Osteopathic Medical and graduated with her Doctor in Osteopathy degree in 2007. Dr. Martin moved to Arkansas for her residency training and graduated with a specialty in Family Practice from University of Arkansas Medical Sciences – AHEC Pine Bluff, AR in 2011.  


Since 2011, Dr. Martin has worked primarily as an emergency room physician and ER medical director.  She has provided ER and family practice services to multiple communities throughout Arkansas.  In 2018, Dr. Martin became the medical director for Freedom House Rehabilitation Center.  This last year she earned her medication assisted treatment (MAT) certification in order to provide pharmaceutical and medical treatment for a variety of substance abuse disorders including: Opioid use disorder, alcoholism, methamphetamine/cocaine abuse, benzodiazepine abuse, and other associated mental health disorders. 


Working in both the primary care setting and the frontlines at the ER, Dr. Martin has seen too often the devastating impact and harm that addiction and drug abuse can have on the patient and their loved ones.  Because of her previous research in opioids and the real-life circumstances she sees in the communities, she believes that providing a clinic with comprehensive and holistic care for addiction is important. 

Dr. Martin lives in Central Arkansas and has two amazing boys, 3 dogs and a cat (that acts like the boss!).  She enjoys cooking, volunteer work, OU football and anything that involves her children!
