Marcia Cavan

Marcia Cavan has been actively training and competing with multiple breeds of dogs since 1980 when she completed the requirements for an AKC Companion Dog (CD) title on her first Pharaoh Hound, Rohirrm's Kestrel. Kestrel was one of the first of her breed to achieve this obedience title. Since then, Marcia has completed numerous obedience titles on 4 different Pharaoh Hounds along with a Whippet, a rescued mix breed, and a German Shepherd Dog.
Marcia and her Pharaoh Hound Bristol (Ch. Galadrial's Dream Weaver UD SC FCh CGC) became the first in her breed in AKC history to obtain a Utility Dog (UD) title. To this date, Bristol is still the only Pharaoh Hound with a UD. Marcia also competed at the 2001 World Series of Dog Obedience with her rescued mixed breed, Jazzabelle, who went on to get her UKC CDX and multiple agility titles. Over the years Marcia has also competed and titled a number of dogs in many other areas of dog training, including tracking and conformation, and has had multiple nationally ranked lure coursing dogs. Marcia participated in many events with her German Shepherd Dog, Navarre, (B'Navarre zu Treuen H�nden BH JJ). Navarre completed his national Dock Dog Junior Jumper title. Marcia and Navarre also enjoyed skijoring during the winter and did some herding as well.
Marcia has had dogs certified as Therapy dogs that made frequent visits to local nursing homes. She currently shares her home with Falke, Navarre's grand nephew, who turned a year old in June 2014. Time will tell what wonderful adventures she and Falke will share.
Marcia teaches Puppy Kindergarten and our CGC classes, and she very much enjoys helping people get off to a wonderful start with their puppies.

Raissa Hinman

Raissa first came to Adele and Northfield Dog Training in the early 1990s with her first Alaskan malamute, Cody. He was not a particularly nice dog, but Adele graciously worked with them, and Raissa became hooked on the �conversation�. In 1997, Sister, another Alaskan malamute, was sent to Raissa, but she was not at all like Cody. Sister was happy and good natured and they had as much fun as a dog and person can have in the obedience and agility rings. Sister earned her MACH and had two litters. Since Sister, Raissa has earned 15 MACHs with Sister's progeny. Her granddaughter Aura, and her son Bootstrap are the first Alaskan malamutes to have earned OTCH pts as well. They also love to sled, and cart and occasionally, weight pull. Over the years, Raissa has taught many classes at the Ann Arbor Dog Training Club as well. She loves to train the dog and looks forward to sharing her experience with you.

Terry Jacobus

Terry Jacobus is owned by three shelties. Having had prior shelties, she looked forward to taking these three everywhere she went, as she did her others. When she brought home a puppy with behavioral problems, that all changed.
Rambo (Shades of Rapscallion AX, AXJ, NF, CGC) put Terry on the path to working with fearful, anxious dogs. Upon attending a working seminar presented by Behaviorist Brenda Aloff she learned that Rambo was not hard wired correctly and would require extensive work and a lifelong commitment to helping him feel safe. She took on that commitment and set out to learn as much as she could to give Rambo a comfortable life.
Rambo has been a working dog at numerous seminars and has worked as a demo dog for various classes. He has competed in agility and has titles in both AKC and CPE. Rambo also holds titles in Rally, Obedience and Musical Freestyle. Rambo has also earned a Canine Good Citizen (CGC).
Terry has attended numerous seminars on behavior and she continues to educate herself about behavior problems. She loves to learn and now holds a certificate as a Veterinary Assistant and is working on Diet and Nutrition.
Terry is a certified agility instructor and CATT (Certified American Treibbal Trainer). Terry holds classes for foundation/management of reactive dogs as well as fun classes such as Treibball and K9 Freestyle.

Karen Tudor

Karen has always had a passion for dogs. Her experience began when she purchased two dominant male puppies that did not get along. This inspired her to research dog behavior and training which quickly became her favorite activity. Karen loves a challenge. She became interested in volunteering with a local rescue where the staff quickly realized she had a talent for training the more difficult to adopt dogs. She has spent many hours working with and fostering dogs to help them find forever homes.
In 2004, Karen purchased a Boxer puppy, Archer, who absolutely loved to jump, causing her to look for something they could do together and have fun. That is when she met Denise Tarby at NDT. While training with Denise, Archer the boxer went on to earn titles in AKC and CPE. Archer became the first boxer in CPE to earn the Agility Trial Extraordinaire Title, CS-ATE. Archer has since been retired and Karen continues to compete with her other dogs in agility, all have been successful in earning titles. She has been training with Denise for over 11 years and has been assisting with beginning agility classes for the last year. Karen truly believes Agility is a Team Sport and both team members must be happy to be successful. She is looking forward to helping her students reach their goals, while having fun with their teammates.

Debbie Harrison

Debbie entered the world of agility back in 1992 with her first Dalmatian, �Autumn� and became hooked on the teamwork and energy of the sport. Since then she has loved, trained and competed with another Dalmatian, 2 Jack/Parson Russell Terriers and 5 Border Collies for a total of over 350 (and growing) titles.
These titles serve to represent the joyous, interactive and FUN relationship Debbie has with each of her dogs. This is also demonstrated by the dog�s work ethic, speed and genuine desire to team with Debbie in whatever dogsport they are training or trialing.
Debbie believes that relationship value, relationship building and TLC (Trust, Leadership and Confidence/Communication) key building blocks in a solid training program. Her goal is to build a dog/handler team (with her own dogs and for her students) that is confident, communicating, connected and collaborative (synergized!).
This is achieved via positive reinforcement training and techniques coupled with motivation/drive, enthusiasm, understanding, clarification, and most of all FUN!!! She enjoys working with all breeds/types of dogs and analyzing the training methods/techniques that most benefit each dog, handler and dog/handler team.
Debbie has attended numerous Clean Run Agility Camps and trained/studied agility with the top trainers and educators in the sport (Linda Mecklenburg, Nancy Gyes, Ann Braue, Karen Holik, Julie Daniels, Jaakko & Janita Leinonen (One Mind Dog), Rachel Sanders, Sylvia Trkman, Stacy Peardot Goudy, Stuart Mah and Pati Hatfield Mah, Jen Pinder, Wendy Pape, Dana Pike, Steve Frick, Webb Anderson, etc. Debbie considers continuing education in the field a must and continues to annually attend multiple seminars/conferences/workshops, etc. to stay updated on the latest training methods and techniques that could benefit her students and their canine partners.
Debbie is a certified Agility Instructor from Julie Daniels� White Mountain Agility School.

Kathryn Gordon

Kathryn Gordon, M.S.W., CPDT-KA has enjoyed training dogs since childhood. Since 2011, she has focused on training and handling search and rescue (SAR) dogs, primarily in the area of human remains detection, although she has also trained trailing dogs and helped to train air scent and disaster dogs. She stays current on research related to scent detection and canine behavior and training, and is active in the scent detection community.
Since her social work days, Kathryn has enjoyed helping people learn new skills, so it was a good fit when she started teaching people dog training in 2012. She has taught weekly puppy and basic manners classes, as well as scent detection classes, ever since—developing one of the first and most successful nose work programs in Michigan before moving to the Ann Arbor area. Kathryn’s students have had success at shows, winning many titles and awards. Over the past few years, Kathryn has been invited to give multiple full- and half-day seminars on scent detection and canine olfaction in Michigan and Ohio.
Kathryn currently trains and works with two human remains detection dogs, a German Shepherd named Hexerei and a Border Collie rescue named Angus. Both her dogs are nationally certified in land cadaver and Hexi is also a certified crime scene detection dog. Kathryn and her two dogs have deployed on various cases in Michigan and Indiana. Kathryn has also mentored others seeking to train detection dogs for SAR, and has acted as an outside evaluator for SAR teams conducting detection certification testing. Kathryn has also been called on to evaluate a variety of pet dogs, taught reactivity management, and worked one-on-one with people seeking to manage a variety of problem behaviors. Kathryn offers private lessons and behavior consults upon request. She is also a certified CGC evaluator.
