Whitney is a native of Arkansas City, KS, who made Stillwater her home in 1998. She graduated summa cum laude from Oklahoma State University with a B.A. in Psychology in 2000, and went on to earn her M.S. in Marriage and Family Therapy from OSU in 2005.
Whitney started a private practice in Stillwater in 2008, where she continues to practice. She currently owns and manages the Warren Alexander Group, a cooperative network of therapists with a variety of interests and specialties.
Whitney is a licensed Marital and Family Therapist and an EMDRIA-certified EMDR therapist, specializing in work with teens and adults facing phobias, anxiety, depression, dissociative disorders, and complex trauma. Her EMDR approach is rooted in somatic and attachment-focused principles, helping clients connect with their healing process on a deeper level. She also incorporates an IFS-informed (Internal Family Systems) lens when working with both clients and consultees, offering a compassionate, parts-aware perspective. Whitney also works with Obsessive Compulsive Disorder (OCD) using Inference-based Cognitive Behavioral Therapy (I-CBT) combined with IFS parts work.
Currently, she’s an EMDRIA-approved Consultant, offering guidance to EMDR-trained therapists working toward certification or navigating challenging cases, especially those combining complex trauma and OCD. She also offers consultations to Consultants-in-Training with EMDRIA primarily utilizing an IFS lens. Clinicians interested in consultation can reach her at whitneylmft@gmail.com.
Whitney is also an AAMFT-Approved Supervisor and licensed supervisor for LMFT candidates in the state of Oklahoma. She loves mentoring the next generation of therapists and provides supervision to both graduate and undergraduate interns at her practice.
Laci moved to Stillwater in 1998 to pursue a Masters degree in community counseling. She completed an internship at Oklahoma Lions Boys Ranch where she conducted groups and individual sessions for adolescent males in a group-home setting. While in graduate school, she also worked at Payne County Family Practice, Inc. as a child advocate, workshop presenter, and therapeutic mediator for families in the divorcing process. While there, she completed alternative dispute resolution training under the Oklahoma Bar Association, advanced mediation training, and assisted in forensic interviewing for court-referred family and divorce cases.
After graduating in 2000, she continued her work at PCYS and concurrently completed a certification in school counseling. Post graduate work also included work in therapeutic foster care, work at Payne County Youth Services, and internships at OSU drug and alcohol clinic and Payne County Counseling. She left OSU to return to PCYS as a clinical director.
Motherhood has presented an opportunity for her to work on a contract basis with PCYS as a therapist focusing on school settings and focusing on cases with Oklahoma Juvenile Authority until August 2014. In joining this private practice, her interest areas are depression and anxiety treatment, family and divorce adjustment, drug and alcohol treatment for individuals and families, infertility counseling and trauma.
Zachary is a therapist dedicated to delivering evidence-based mental health care across the lifespan. He holds a graduate degree in Counseling Psychology from the University of Central Oklahoma, where his training emphasized the use of empirically supported treatments. His approach is grounded in Cognitive-Behavioral Therapy (CBT) and includes specialized interventions.
Zachary has extensive experience working with children, adolescents, and adults. With younger clients, he frequently utilizes Parent Management Training (PMT) to support caregivers in addressing oppositional behavior, inattention, and mood dysregulation. He is also trained in Comprehensive Behavioral Intervention for Tics (CBIT)—the gold-standard, non-medication treatment for tic disorders, including Tourette’s Disorder. For clients experiencing Obsessive-Compulsive Disorder (OCD) and Anxiety conditions, he implements Exposure with Response Prevention (ERP), a structured and highly effective treatment that helps individuals gradually confront feared situations while reducing compulsive responses. ERP is widely regarded as the most effective intervention for OCD and is adaptable for use with phobias, health anxiety, and other avoidance-based concerns. He takes a collaborative and individualized approach to care, using structured, measurable interventions that align with each client's goals. He provides inclusive, secular treatment to clients of all backgrounds and belief systems.
In addition to individual therapy, Zachary facilitates group-based interventions for both parents and youth. He has led PMT groups that help caregivers apply consistent, evidence-based strategies to manage challenging child behaviors in a supportive, skills-focused environment. For adolescents and adults struggling with excessive worry, social anxiety, or panic, he also leads CBT-based anxiety groups that incorporate psychoeducation, exposure exercises, and cognitive restructuring to build lasting change.
Outside of clinical work, Zachary is an active member of the U.S. Chess Federation. He plays and coaches competitive chess and has helped direct multiple tournaments across Oklahoma. In his free time, he and his wife enjoy fishing, cooking, gardening, and reading or listening to science fiction and fantasy novels.

Ruth is a bilingual (Spanish and English) therapist based in Oklahoma who works with people who are tired of pretending and ready for something more honest.
Her clients are often parents, teens, and young adults who feel stuck, overwhelmed, or emotionally shut down. Many are navigating life transitions, trauma, anxiety, or seasons of uncertainty where nothing feels clear and everything feels heavy. Ruth creates space for those who are used to holding it all together to finally exhale.
Her approach to therapy is grounded in authenticity and connection. She believes the therapy room should be a place where you don’t have to perform, fix everything, or have the “right” answers, it’s just a place where you get to be fully human. With a warm, down-to-earth style, Ruth helps clients move toward clarity, emotional connection, and a deeper understanding of themselves.
Ruth is especially passionate about creating a space where clients feel safe to show up as they are ( messy, unsure, healing) and to explore their experiences without judgment. Because therapy isn’t about having it all figured out; it’s about having a place where you can be real.
If you’re interested in working with Ruth you can schedule a 15 minute consultation through contacting the Whitney Alexander Group or emailing directly at ruth.chapman@schustercounseling.com

At Warren Alexander Group, Tiffany C. Poe, MMFT, LMFT Candidate, offers a counseling space that feels both grounded and genuine, where clients can show up honestly without feeling like they have to have everything figured out first. Tiffany works with couples, families, teens, and young adults who are longing for deeper connection, healing, and a better understanding of themselves and the relationships that matter most to them.
Tiffany’s approach is relational, collaborative, and deeply rooted in the belief that people are shaped by their experiences, relationships, and attachment stories. She integrates Emotionally Focused Therapy (EFT), Internal Family Systems (IFS), and attachment-focused therapy to help clients slow down, make sense of painful patterns, and move toward healthier ways of relating to themselves and others. Her style is warm, client-led, and conversational while still providing intentional direction and care throughout the therapeutic process.
Tiffany has experience working with couples across many seasons of relationship, from newly married couples learning how to build a life together to long-term partners carrying years of hurt, disconnection, resentment, or transition. She welcomes couples in all stages and circumstances and strives to create a space where both partners feel heard, understood, and emotionally safe enough to engage in meaningful change together.
Before becoming a therapist, Tiffany spent years serving in campus ministry and youth ministry, experiences that continue to shape the way she connects with people today. Her background fostered a deep appreciation for walking alongside others through uncertainty, pain, growth, and life transition with empathy, authenticity, and compassion.
Tiffany values creating a counseling environment that feels human, not clinical or one-sided, and where clients can feel supported while doing the difficult but meaningful work of healing, reconnecting, and growing forward.
