Meet Our Team

Jessica Dorrington - Bethany Physical Therapy

Jessica Dorrington, PT, MPT

Clinic Director | Physical Therapist
  • Board Certified Clinical Specialist in Orthopaedic Physical Therapy
  • Certified Manual Physical Therapist
  • Certified Strength and Conditioning Specialist
  • Pelvic Rehabilitation Practitioner Certification

Your body has incredible power to overcome many physical challenges and heal. The human body is complex; it is fascinating how every component is related. We must look at your body as a whole when addressing an injury. We must look at every system and find the driving source behind the issue to truly resolve that issue and prevent recurrence.

If you are an individual with a complex history, unclear answers, or you have frequently struggled with chronic and long-standing issues, then you are where my passion truly lies. In daily practice, I see the combination of my advanced orthopedic training and breadth of knowledge on pelvic floor health bring answers and improved outcomes to so many patients when looked at as a whole person. Throughout my career tenure, I have been able to combine my interests of orthopedics, pelvic floor rehabilitation, manual therapy, and sports therapy.

Through extensive training and advanced clinical experience as a pelvic floor specialist since 2002, my practice has evolved into treating all types of patients, including urologic, gynecologic, obstetric, and colorectal conditions. My clinic focus includes treating men, women, and children for pelvic rehabilitation through collaboration with multiple medical providers. To ensure advanced competency, I have passed rigorous testing to reach a Pelvic Rehabilitation Practitioner’s Certification, which only 150 individuals have received nationwide. I have been given the opportunity to be the primary mentor for pelvic health in not only my clinic, but within Therapeutic Associates, and I love to teach my colleagues. I am one of less than 70 PTs in the country to be educated in intrapartum pelvic care. This has allowed me opportunities to take part in patient deliveries and assist with patient’s successful pelvic health, a healthy baby, and a healthy mom. I combine pelvic rehabilitation education with advanced training in ultrasound imaging to provide a more extensive treatment option for anyone dealing with low back, abdominal, or pelvic issues.

Over the years, it has been a pleasure to participate in extensive education for both the general public and the medical community. I have been honored with the role of key speaker for several years at the Oregon Podiatry Association, as well as teaching about the complexity of the foot in its relation to the entire body. I have served as a speaker for both the National Conference for American Medical Assistants and the Oregon Chapter (for AMA), teaching providers how much influence the pelvic floor has on continence, low back, and hip pain. I have recently been invited to speak at the United Nations Platforms on the topics of ‘reducing motherhood mortality through pelvic floor education’ and ‘how we can use birthing positions and proper pushing techniques to reduce cesarean delivery and pelvic floor trauma’ (Spring 2017).

As a collegiate cross country and track & field athlete, I found my passion for the body, which helped me pursue and receive my Master of Physical Therapy from the University of North Dakota in 2002. Through my own injuries and continued competition in road races of 5K to marathon distance, I have a special passion for helping athletes. From recreational level to elite athletes, I enjoy helping them reach their maximum rehab goals, including properly fitting them on bicycles and analyzing their gaits. I have had the honor to work with several professional skiers and runners and am on consultative status for the Nike Oregon Project working with female athletes to ensure their lumbopelvic region is in optimum function. Each year, I help out the Westview and Sunset High Schools by providing free injury screens to their athletes.

In the realm of orthopedics, I am a Board Certified Orthopedic Clinical Specialist through the American Physical Therapy Association. While less than 2 percent of physical therapists obtain these credentials, I believe it is important to test our knowledge and improve our skills as providers. I have also obtained my advanced certification in manual therapy through the North American Institute of Orthopaedic Manual Therapy and am a Certified Strength and Conditioning Specialist (CSCS). I have been an active member of the American Physical Therapy Association (APTA) since 2002 and believe in the continued support of our important profession. I am trained and certified in the Augmented Soft-Tissue Mobilization System and have specialized training and education in bike fitting and gait analysis for runners. I have had the opportunity to receive advanced training in the neuroscience of pain as well as learn the newest research on how our body interprets pain.

Since 2005, it has been an honor to be the director of Bethany Physical Therapy. Because I believe every individual has potential, I lead my team in the commitment to make exceptional results accessible through compassionate therapeutic care and injury prevention. I believe in leading a family-oriented, servant-led business of integrity, where we pursue our vision using our talents and strengths and make a positive contribution to the lives of our employees, patients, and referral sources.
In my leisure time, I enjoy spending time with my husband and sons. As recreational enthusiasts, you can find us skiing, snowboarding, running Forest Park, doing yoga, or enjoying arts and crafts with our children, Caleb and Henley. As my accolades display, I am an education junkie who continues to live my life’s passion through over 1200 combined hours of post-graduate clinical education. I take pride in ensuring you the most up-to-date, research-based treatment to improve your physical therapy results.

I would be honored to be a part of your medical team and look forward to hearing about your story. Let’s work together to get you back to what you love to do.

Good health is not a static state of being, like life it is ever-changing and evolving. It requires conscious and constant effort to maintain.

Lisa Sullivan, BSN

Certified Health Coach & Registered Nurse*

Lisa Sullivan is a RN, Certified Health Coach, and Certified Food for Life Instructor. She decided to become a health coach after 24 years of practicing nursing and seeing the increase in obesity and chronic diseases in pediatric and adult populations. Healthcare focuses on symptom management with medications and invasive procedures as the treatment of choice, with less focus on nutrition and lifestyle management. A plant-based diet and active lifestyle, along with stress management can change the course of these chronic diseases and improve and/or eradicate them completely. Lisa is passionate about prevention and wants to share this with people who want to improve their health by losing weight, lowering their cholesterol, decreasing their need for diabetes medication, and ultimately feeling more energized and full of life…a healthy life.

Health and wellness are our most valuable assets. Over two years ago, Lisa and her husband had their annual physical and found out their cholesterol was well over 200 and triglycerides were above normal. This was after she completed three Ironman competitions, so exercise was not her limitation! After completing an eight-hour course called Enhancing Health with Plant-based Nutrition, Lisa and her husband decided to incorporate a plant-based diet into their daily lives, including fruits and vegetables, grains, legumes, nuts, and seeds. She did her homework, and it took a month to really understand how to make the switch, but she did it and learned a lot through the process. After just six months they went back to their physician and found that her cholesterol dropped from 252 to 168 and her husband’s dropped from 212 to 149. Both of their triglycerides dropped 20 points. Lisa was astounded and convinced that she could help others improve their health with diet and lifestyle. And it can be done in a fun and tasteful way!

Ultimately, Lisa was energized. This method of eating cured her IBS and improved her allergies dramatically. Nutrient dense, whole foods are the key to unlocking a life of good health. Are you ready to start the journey? She is ready to be your guide on the side in the journey of everlasting health. Come catch wellness and live a life of joy.

Lisa is a Certified Food for Life Instructor and decided to add this very reputable certification to her resume because she truly believes in plant-based nutrition as ‘food for life’ for prevention and treatment of chronic diseases. She feels confident that this evidence-based program will provide her with the added skills and science backing to get her out into the community to teach this important message. Lisa began this journey in July 2014. She is available to teach classes in Portland, Oregon and any outlying areas in Oregon, as well and Vancouver, WA. Her favorite low-fat vegan recipe is the Tempeh Broccoli Saute’.
