Cody Zaiontz is an LPC in the state of Texas. He has been providing counseling services to a variety of clients, who have sought help for many different types of mental health conditions, for over 5 years. Cody completed his undergraduate education in San Marcos, Texas at Texas State University and earned his bachelor's degree in psychology.

His practicum training took place at the UT Health Science Center in San Antonio, Texas where he was trained in Cognitive Behavioral Therapy, Dialectical Behavioral Therapy, Motivational Interviewing, Solution-Focused Brief Therapy, and crisis management. Upon graduating with his master's in counseling, Cody worked for 2 years helping individuals diagnosed with a serious mental illness (schizophrenia, bipolar disorder, etc.) in an inpatient psychiatric hospital. He then learned how to provide outpatient counseling services, both in-person and through a secure telehealth platform. In his private practice, he worked with adults dealing with substance abuse, PTSD, depression, anxiety, and family issues. He also helped his clients work towards weight loss goals, learn ways to improve sleep, learn ways to increase their social support system, and learn other skills that will help them live a happier, more fulfilled life.

Her style is collaborative and goal focused, while also encouraging insight into patterns or experiences that may have been difficult to acknowledge. She values transparency and views respectful conflict and open feedback as meaningful parts of growth and the therapeutic process.

Yumi begins by gaining an understanding of the concerns that bring a patient to therapy, along with relevant personal history. Together, she and the patient identify therapy goals and develop a treatment plan, often with a 3–6 month framework. As life circumstances and challenges evolve, she works collaboratively with patients to adjust goals and approaches to best support ongoing progress.

Earl Andrew De Guzman, MD

Staff Psychiatrist

Dr. Earl De Guzman is a psychiatrist who values therapeutic partnership, working with patients to balance symptom relief with meaningful self-exploration. He earned his BS in Psychology from the University of California, Davis, and his MD from Ross University School of Medicine.

Dr. De Guzman takes a collaborative, patient-centered approach, creating a warm and nonjudgmental environment. He listens deeply, asks thoughtful questions, and encourages honest exploration of symptoms and underlying patterns. He values authenticity, curiosity, and respect for each patient’s unique experiences. While symptom relief is important, his goal is to foster self-understanding and long-term growth. He works best with patients open to collaboration and motivated for change, whether through medication management, therapy, or both.

Dr. De Guzman begins with a consultation phase to ensure a good fit, listening carefully to understand each patient’s challenges and goals. Together, he and his patients build a working alliance by clarifying difficulties, identifying realistic changes, and exploring deeper patterns. When appropriate, he prescribes medication thoughtfully, aiming to support therapy rather than replace it. Each session integrates supportive and psychodynamic elements, combining medication review with therapeutic dialogue. Treatment plans are regularly revisited, allowing flexibility and growth, with the ultimate aim of empowering patients toward lasting change.
