Meet the Team

Helping people improve their quality of life by delivering excellent therapy services within a compassionate and comfortable environment.

 Sharon Assink, OTR/L,CHT


Sharon Assink is an Occupational Therapist and a Certified Hand Therapist who earned her degree from the University of Alberta at Edmonton.

She spent 15 years on the staff of the Royal Inland Hospital in Kamloops, B.C. as an occupational therapist working in the outpatient, inpatient acute care and chronic pain units, and moved to the U.S. in 2005 after meeting her husband. Shortly after moving to the US, Sharon joined ReBound and has been an amazing addition to our outstanding Hand Therapists.

“I love to see all the small changes that happen as patients come to therapy,” she says. “Some can get all excited because they can hang on to a fork. We all take for granted the things we can do, and it’s exciting to see patients gain new appreciation for the activities they took for granted before their injuries.”

Sharon is Canadian and has traveled alone to Europe, Australia, New Zealand and the Cook Islands, as well as pedaling across Canada in 2004 with a friend. The duo carried their own gear during the 10-week trip that Assink jokes was her farewell to Canada tour.   She continues to cycle, now with her husband, exploring areas such as northern New Mexico, Colorado, and the Oregon Coast.

Sharon plays piano and guitar and enjoys being a part of her church’s music ministry. She began her musical career by learning how to play the pipe organ on the largest pipe organ in Southern Alberta. She lives in Bellingham with her husband and daughter and likes to bike, hike, read and camp in her spare time and looks forward to exploring more areas in the US with her family.


Alex Bartl, OTR


Alex Bartl is an occupational therapist and a hand therapist who enjoys making new splints. While some may think it’s an odd hobby, to him, it’s a chance to see how he might be able to make them better. If you’re wearing a Hinged PIP Joint Splint, thank him. He invented it.

“I’m always tinkering,” he says. “While most people talk about thinking outside the box once in a while, I’m thinking that way all the time. When I make a splint, I’m always thinking about how something might work better if you tweak it in some way.”

Bartl grew up in a logging and farming family, lettered in four sports in high school and excelled at cutting down and felling dead trees on fire. He was a forest fire fighter in high school and college, and spent seven years in the Reserve Army Medical Corps. He received his degree in occupational therapy from the University of Puget Sound and opened the first private practice hand therapy clinic north of Seattle in 1981.

He grew his practice to three clinics in 17 years and then sold it. Bartl joined ReBound in 1999 soon after Lori Libolt and Christine Nelson opened the company.

Now with over 30 plus years of experience, Bartl still loves coming to work each day. “Each patient is unique and different even though a lot of the diagnoses are the same,” he says.

Bartl is the husband of a fantastic pediatric RN, and the father of a former college-level hockey player, and an outstanding football lineman turned power lifter. The real loves of his life are his  two  granddaughters, and one grandson. Bartl served on the board of directors for the Boys and Girls Club for 10 years, and served as its president for two.


Kevin Rupp, DPT


Born and raised in central Washington, Kevin moved to Bellingham for his undergraduate education and fell in love with the area.

Kevin  loved the synergy he experienced with a physical therapist when, as a high school high jumper, he was injured. He was also fascinated with bones, muscles and how they interacted to produce movement thus propelling him into the field of PT.

“I really enjoy the relationships we get to have with patients,” Rupp said. “In the health care world, we are unique because we see people in rehab, and see them over several weeks. We get to know them, and what they like and don’t like, and we can help them and give them tools to participate in their recovery.”

He returned to Bellingham in  2009 after graduate school to begin his career and has been working at ReBound since.  While getting his doctorate in physical therapy, Kevin assisted in research investigating functional movement patterns before and after total knee replacement and has an ongoing interest in rehabilitation of joint replacement surgery.  He treats a variety of acute and chronic musculoskeletal conditions and enjoys working closely with patients to educate and empower them to make positive changes in their lives.  Kevin has a particular interest in fall prevention in the elderly and has specific training in Vestibular Rehabilitation to treat dizziness, vertigo and other balance disorders. Kevin is the lead PT in our Bellingham clinic.

Out of the clinic Kevin enjoys spending time with his wife (whom he met in the seventh grade), daughter and  son.  He enjoys hiking, photography, playing guitar, cooking and cheering on the Seattle Seahawks.

Lori Libolt, OTR/L, CHT


Lori Libolt is one of the founding members of  ReBound. A certified hand therapist, Lori leads the company’s hand therapy team and is  an integral part of  pursuing excellence in Occupational and Hand therapy within the clinic. She is driven to provide top quality care with compassion for all of her patients.

A cum laude graduate of the University of Washington, Lori worked for Swedish Hospital, Kaiser Permanent, and Sunnyhill Sports Physical Therapy, and was an instructor at Chaffey College before starting ReBound.

She also sang at Carnegie Hall and the Royal Alberts Hall in London, England as part of America’s Youth in Concert, and has a recording to prove it. Today, Libolt belts out tunes on the guitar and piano as a member of her church band, writes and plays in a duet with her youngest daughter, and enjoys giving concerts, especially those that raise money for special needs. She also loves to bake cookies, pies, and cinnamon rolls among other goodies.

Libolt, whose laughter can fill a room, loves her job: “What could be better than helping someone walk through a tragic injury and come out with a smile and hope of a normal life?” she says.

When she is not at work she enjoys singing, composing music with her youngest daughter, laughing with her husband or chatting with her oldest two children and their spouses.


 Denise Dewey, PT/ATC, AT/L

Denise joined the ReBound team in 2012.  Denise returned to college while raising 4, yes 4 young children.  She became a Certified Athletic Trainer and then went on to get her PT degree from the Medical College of Ohio.  Denise has an extensive and varied background having worked in hospitals, long term care facilities as well as a variety of outpatient practices.  Denise loves “connecting” with and educating her patients on how to overcome their injuries.  She has volunteered with the Lynden Christian football team as their Athletic Trainer and still enjoys being on the sidelines on those cold and rainy Friday nights under the lights.

When Denise isn’t working with patients she enjoys spending time with her husband hiking, camping and volunteering with her church.  Her greatest joy comes from spending time with her 4 adult children and  3 grandchildren.


Christine Nelson, ATC, AT/L


With her short spiked hairdo, ever-changing colorful glasses and wide smile, you’d think ReBound owner Christine Nelson is an outgoing boisterous gal who’s very contemporary. And you’d be wrong.

Nelson, a certified athletic trainer who’s in charge of ReBounds operations, is a bit conservative – but not so much that she isn’t afraid to reveal a little wild streak. Hence the unique, colorful and funky glasses, which she began collecting in 2001. At last count, her collection totals 30+.

“Not a day goes by that someone, somewhere does not comment on my glasses,” Nelson says. “Just this morning two people stopped me in Starbucks to ask about my glasses.”  She is also known for her varied collection of unique and sometimes wild shoes.

Nelson has a BA in exercise science from Western Washington University and annually participates in professional development courses in the area of treatment and athletic performance enhancement. Her passion is making a difference in the lives of her patients and providing a fun, enjoyable work environment for the company’s 22 employees.

Christine volunteered as the Athletic Trainer for the  Lynden Christian School sporting events  for 21 years and now serves at Bellingham High School on a volunteer basis. She has also volunteered her time at Northwest Youth Services, a nonprofit that serves at-risk youth and sits on the Board of Directors for Evergreen Supported Living a non-profit agency serving the needs of  developmentally disabled adults.

In her spare time, Christine enjoys playing with her 3 large Greater Swiss Mountain Dogs, spending time with family and cheering on the Seahawks.   She  is happiest when she is outside enjoying nature, cooking and barbecuing for her friends and family  or working on a multitude of home projects.


Louise Nelson, PTA


Louise joined the practice in May of 2014.  She is a graduate of Whatcom Community College’s PTA program where she realized her passion for the field of Physical Therapy and fascination with the human body.   Prior to working at ReBound Louise worked in a private outpatient therapy practice.

She stays up to date with continuing education classes that focus on orthopedic conditions and hands on training.  She has studied a variety of manual therapy techniques and is constantly developing her skills.  She has extensive training in aquatic therapy and loves working with folks in the pool.  “I love helping patients develop the strategies and ability to be independent and active with fewer symptoms.”

In her spare time Louise enjoys being involved in her church,  exploring the beautiful Pacific Northwest, camping, traveling, visiting art museums, attending plays and any chance she has to be in or on the water.  She says each of these activities are made infinitely better when they include her husband,  children and grandchildren .


Sarah Kilgus, COTA

Sarah joined ReBound in July of 2014.  She joins Lori, Alex, Sharon and Katie in the OT department and has been a superb addition to our OT staff.  She graduated Summa Cum Laude from Adventist University of Health Sciences and has worked in a wide variety of clinical settings prior to landing here at ReBound.  Sarah has been an excellent addition to our staff and brings fresh and  exciting ideas to the clinic.

Sarah is a transplant from sunny Florida and is enjoying exploring the outdoors of the Pacific Northwest. Sarah loves spending time hiking, skiing and being on the water with her husband and 2 dogs (Boe & Willow) .

Jenny Simmons, LMP

Jenny grew up in Whatcom County and attended Nooksack Valley High School where she was an outstanding athlete.  She went on to play volleyball at the collegiate level in Alaska.  Upon her return to Whatcom County, she spent several years coaching volleyball and basketball at Nooksack.

When she is not doing massage or teaching yoga Jenny enjoys spending time with her husband and 2 young sons.

Nadia Chayka, OTR

Nadia  joined the team at ReBound in April of 2017.  She is a 2016 graduate of Eastern Washington University  with her Masters in Occupational Therapy. Nadia is studying for her Certification in Hand Therapy.

When asked what she likes best about being a therapist she states, “It is the best feeling when a patient can return to the activities they love that they were able to do before their injury.”

When Nadia isn’t busy working she prefers to spend time outdoors with her husband, hiking and camping. She has a large family and loves spending time with them.

Melodie Langstraat, PTA

Melodie is another home town girl.  She attended Lynden Christian schools prior to attaining her PTA degree from Whatcom Community College and joined us in 2014.

After taking several years off to care for her 2 sons, we are thrilled to have Melodie join our team.  She brings a wealth of knowledge and is loved by her patients.

When Melodie isn’t at the clinic she is busy doing Cross Fit, watching her sons athletic events and spending time with her family.

Christopher Mitchell, DPT

Chris was born and raised in Whatcom County. He attended Nooksack Valley High School and then Western Washington University for his undergraduate degree in Kinesiology. Chris was a member of WWU’s basketball and track & field teams while at Western and was an integral part of the 2012 NCAA Division II National Championship men’s basketball team. His passion for the field of health and physical therapy began while attending WWU.  Chris received his Doctorate in Physical Therapy from Pacific University. He also had the unique opportunity to participate in a clinical internship at The Maitland Cottage Children’s Orthopedic Hospital in Cape Town, South Africa while in physical therapy school. “I love to travel, and I love physical therapy. It was a great opportunity to work with children in a healthcare system that was vastly different than I was accustomed to, and it will always be one of my favorite experiences”.

Upon graduation, Chris and his wife, Ali, whom he met while attending WWU, returned home to Whatcom County, where he joined the ReBound team in the Fall of 2016. Chris enjoys treating a variety of conditions, educating people on their recovery, and enabling people to participate in the activities they love. “I enjoy the role of a physical therapist and what we promote to people.  Every individual is unique when they come in for physical therapy, and they deserve a unique experience tailored specifically to them. I like providing that”.

Outside of the clinic, Chris enjoys spending time with his wife, their new daughter and dog Lucy. He is an avid road cyclist and participates in a number of races each year.  Chris and Ali are world travelers and take every opportunity to expand their horizons and visit exciting places worldwide.
