A Biological Approach to Dentistry
Breathe new life into a healthy, straight smile – your way.
At Spring Oaks Dental, we treat the mouth as the gateway to overall health. Spring Oaks Dental in Spring, Texas, was founded in 2015 by Dr. Kassi Klein. While the practice began as a general dentistry family practice, it quickly evolved into North Houston’s premier biological dentistry practice. With airway and biocompatible dentistry, the Spring Oaks Dental team is always striving to care for patients and keep an eye on their overall and future health.
Our goal is to be a positive, supportive, uplifting environment for both our patients and team members. Our focus is to provide compassionate, comprehensive dental care by taking into consideration not just the mouth but the body as well. We will continually be a judgment-free, safe place for patients to start or continue their individual journeys with support. We want to empower patients to take charge of their health, working to educate patients and approaching treatment decisions with transparency.
Great office. Prompt, courteous and helpful. Both dentists take time to consider your immediate and future issues and completely answer questions. I appreciate the holistic approach to my dental health.

Kassi Klein, DDS
“When you breathe better, you sleep better, and when you sleep better, you feel better. When you feel better, you live better!” — Dr. Kassi Klein
Dr. Kassi Klein is passionate about helping people to improve their overall quality of life. She graduated from Texas Tech University with a bachelor’s in mathematics and a minor in English before moving on to study at the UTHealth School of Dentistry, where she obtained her doctorate in dental surgery in 2012. Dr. Klein was drawn to dentistry because she’s always just loved people’s smiles, and being a dentist has allowed her to help people make meaningful changes in their overall health and well-being.
Dr. Klein furthered her education and training by completing a one-year comprehensive TexMAX MaxiCourse on implant dentistry through the American Academy of Implant Dentistry. As part of this program, Dr. Klein completed over 300 hours of surgical and instructional education. After starting to practice implant dentistry, she began observing a strong connection between airway size and a wide range of health and dental issues in her patients. Following her curiosity, she began learning about airway dentistry and went on to continue her education by completing a residency program with Airway Health Solutions. She is also an ambassador for The Breathe Institute.
In 2018, Dr. Klein’s mom, Karri, had a heart attack, and the cause was never determined. After scanning and evaluating her mom’s airway, Dr. Klein discovered a considerable airway insufficiency. Her mom had numerous symptoms related to airway insufficiency, including fatigue, diabetes, fibromyalgia, and anxiety. A sleep study confirmed Dr. Klein’s findings, revealing severe obstructive sleep apnea. Seeing firsthand the effects of a restricted airway and the subsequent healing journey through dental appliance therapy has only increased Dr. Klein’s dedication to airway dentistry.
Dr. Klein maintains memberships in many dental organizations to stay current in the latest developments and to continue expanding her knowledge base. A few of those organizations include:
- Academy of General Dentistry
- American Academy of Dental Sleep Medicine
- American Academy of Physiological Medicine & Dentistry
- International Academy of Oral Medicine & Toxicology
Additionally, Dr. Klein is SMART (Safe Mercury Amalgam Removal Technique) certified and a Vivos Integrated Practice provider and a Vivos Clinical Advocate, mentoring other doctors to become airway providers as well.
Outside of the office, Dr. Klein loves spending time with her husband and children, swimming, grilling, and touring wineries.
Rachel Buckley, DDS
“I chose biological and airway dentistry because I am a huge fan of treating the body in a natural way first.” — Dr. Rachel Buckley
Born and raised in Houston, Dr. Rachel Buckley completed her undergraduate studies at Houston Baptist University, where she obtained her bachelor’s degree in biology and was awarded recognition as Biology Student of the Year. She then went on to earn her doctorate in dental surgery from UTHealth School of Dentistry and the Professional Collegiality Award from the Ninth District Dental Society. While at the University of Texas, she coordinated and led multiple events for UTHealth School of Dentistry students. These events focused on the five pillars of human wellness. Dr. Buckley has a true passion for leadership and learning.
As a child and teen, Dr. Buckley struggled with dental issues. She went to many dental offices for treatment and orthodontic care and experienced firsthand the impact a negative and a positive experience can have on an individual’s oral health. Wanting to provide others with the best possible care and dental experiences, Dr. Buckley chose dentistry as her lifelong profession. She loves working with patients of all ages, and her mission is to always create a comfortable environment for her patients and her team members. She is continually learning the latest about airway dentistry, restorative procedures, and advanced dental technology through continuing education programs.
Dr. Buckley is a member of several organizations. Some of those organizations include:
- International Academy of Oral Medicine & Toxicology
- American Dental Association
- Texas Dental Association
Dr. Buckley is also certified as a Vivos provider and is certified in laser dentistry by Solea. She has additional advanced training with sleep appliances targeted at treating sleep apnea.
When not treating patients, Dr. Buckley loves to travel to different countries, bake amazing desserts, golf on different courses in the Spring and Woodlands areas, and spend time with her husband and family.
Blake Swonke, DDS
Dr. Blake Swonke followed in his father’s footsteps into the world of dentistry. Growing up watching his dad transform patients’ smiles and lives, Dr. Swonke became inspired by the opportunity to combine science, precision, and personal care. He earned his undergraduate degree in Biology from The University of Texas at Austin before continuing his education at The University of Texas Health Science Center at San Antonio, where he graduated from dental school.
Dr. Swonke completed an Advanced Education in General Dentistry (AEGD) residency, further refining his skills in a wide range of dental procedures. This additional training allows him to handle everything from advanced restorative treatments to complex cases, enabling him to offer comprehensive care to his patients. His focus is on providing high-quality, patient-centered dental care that improves not only oral health but also overall well-being.
Professional Memberships and Organizations:

Outside of work, Dr. Swonke is newly married, and he and his wife—a fellow dentist—are embracing this exciting chapter of their lives together. While they don’t have children yet, their dog keeps them on their toes and brings plenty of joy to their household. In his free time, Dr. Swonke enjoys exploring new restaurants, working out, and experimenting with new recipes in the kitchen. He even grows his own peppers to add a fresh touch to his meals. A fan of outdoor walks with his wife and dog, he finds these moments a great way to unwind and recharge.
Dr. Swonke has a hidden talent for growing peppers and a passion for photography, often capturing the beauty of nature through his lens. When he’s not behind the camera, you might find him watching Formula 1 races or catching the latest movie releases.
