Meet Our Team
Director & Co-Founder: Sarah Vann
Sarah Vann (previously Herr Davies), M.S., CCC-SLP is a Speech Language Pathologist for Portland Public Schools and private practice in Portland, Oregon. She has a strong interest and passion for stuttering, which has quickly become an area of specialty for her in the field. While working with clients who stutter, Sarah's mission is to provide support in helping individuals become confident as a person who stutters through treating all aspects of stuttering, including attitudes and emotions and fostering community, instead of focusing on the stuttering behaviors themselves. It is because of this belief in her treatment approach and a need for more community and social opportunities for those who stutter, that she joined forces with Kristin Mangan in late 2015 to create the inaugural session of Camp More in 2016.
Beyond camp, Sarah is actively involved in the stuttering community. After starting the process of creating Camp More and witnessing the positive impacts of Kristin's support group for teens who stutter (TOPS), she started a version for kids (KOPS), now blended together called More Meetups. Sarah participates regularly in the Portland chapter of the National Stuttering Association (NSA)-an adult support group for people who stutter, after co-leading for it for 3 years. Sarah has presented on the topic of stuttering to fellow SLPs, educators, children, and families, and is a constant resource to other area SLPs looking to further their development of skills in holistically evaluating and treating stuttering.
​
Sarah is incredibly proud of Camp More and it's success the past several years. She is beyond excited for the continued growth of Camp More including More Meetups. When not working or with her groups, Sarah is usually always kept busy by her three teenage and one toddler sons: Bryton, Maddox, Jonas, and Colton. Sarah also enjoys cooking, reading, hiking, arts and crafting, and spending time with her friends and family.
Assistant Director & Co-Founder: Kristin Mangan
Kristin Mangan, M.A., CCC-SLP is an Assistant Professor and Speech-Language Pathologist at the Institute on Development and Disability at Oregon Health & Science University (OHSU) in Portland, Oregon. She has specialized in stuttering, as well as feeding and swallowing, for the past 16 years. She is an active member in the FRIENDS, the National Association for Young People Who Stutter, as well as in the National Stuttering Association (NSA). She has presented both regionally and nationally on the subject of stuttering to children, parents, educators, and other professionals.
​
On a local level Kristin sees children, teens, and young adults who stutter for evaluations and treatment at the Child Development and Rehabilitation Center (CDRC). Given her strong beliefs that counseling, community, self-acceptance as a person who stutters, and building confidence is an imperative part of one's stuttering journey, she started a support group for teens who stutter, called TOPS: Teens Out Promoting Stuttering (now shared with kids and called More Meetups). This has been a source of tremendous joy for Kristin and has resulted in growth and excitement for the teens (and now kids) that participate regularly.
​
When not at work, Kristin greatly enjoys spending time with her family and friends, mainly her son, Sive. She also loves traveling, exercising, reading, cooking, and gardening.

Natalie Griffin
Natalie Griffin is a speech-language pathologist for Klamath Falls City Schools in Klamath Falls, Oregon. She received her Bachelor's degree in Speech and Hearing Sciences from Portland State University in 2013 and her Master's in Speech-Language Pathology from Pacific University in 2015.
​
Natalie's passion in the world of speech-language pathology is working with kids and teenagers who stutter. Natalie received speech therapy through the public school system throughout her life. She spent her teenage and young adult years searching for a reason why she was never "cured" of stuttering and returned to speech therapy many times. It wasn't until she attended the PSU Speech and Hearing Clinic and started to learn about stuttering that she began to accept and even appreciate her speech. She now believes there is nothing better for kids and teens who stutter than the chance to share life experiences and discuss stuttering openly with one another. Outside of work and stuttering, you can find Natalie baking, drinking copious amounts of coffee, spending hours in a bookstore, or kayaking with her husband, Anthony.
