Our Team

Rocky Mountain Veterinary Rehabilitation (RMVR) provides rehabilitation and pain management services to restore and maintain your pet’s quality of life. We offer a holistic view of your pet’s health, identifying particular challenges that can be solved by considering all care options: Traditional veterinary medicine (surgery, medications, and more), combined with Eastern and integrative approaches that look at complete body systems and how to improve them.

Led by Dr. Karyn Fein, our staff builds trusted relationships with your family to develop custom treatment plans administered in-office with daily home care that results in the best outcomes. Our plans treat your companion with an eye towards maintaining a lifetime of good health.

Advice + Compassion
We also serve as compassionate care advisors. Oftentimes, health options feel limited. We support your pet post-trauma or surgery, and offer non-surgical management therapies when appropriate. Senior pets get the attention and care needed to feel and function better during their golden years while pets with cancer or chronic disorders can find relief.

Our Goals for You + Your Companion
Beyond your pet’s renewed comfort and mobility, our goal is to help you assimilate information from your primary care and veterinary specialists to help you make the best decisions for your family. We work as attentive case managers, maintaining regular communications with both you and them about your pet’s health.

Jennifer Tucci, DVM, CVA, CVMMP, CVFT

Veterinarian, Practitioner of Traditional Chinese Veterinary Medicine

Dr. Jen Tucci’s clients often describe her as a calm, steady, and reassuring miracle worker. Using Traditional Chinese Veterinary Medicine methods such as acupuncture, chiropractic-style joint mobilization techniques, food therapy, herbal remedies, and more, dogs and cats that have presented with extreme pain express wiggles of wellness while under her care.

Dr. Tucci completed concurrent studies in Western veterinary care and Traditional Chinese Veterinary Medicine (TCVM). She frequently used modalities like acupuncture to treat seizures, back injuries, and other urgent conditions during her work in emergency veterinary clinics. Over time, she identified pets who weren’t thriving with Western care alone, so she dedicated her practice to TCVM, embracing its central thesis: That we can improve an animal’s overall health by assessing and treating the imbalances that result in illness.

Dr. Tucci sees powerful results with acupuncture: Dogs able to hop back onto their favorite couch, for example. Her own asthmatic kitty breathes easier and enjoys increased mobility from a regimen of Chinese herbs.

Karen Gertson

Karen Gertson

Rehabilitation Assistant / Operations Manager

Karen is a highly-skilled veterinary technician who conducts follow-up care under the supervision of RMVR’s veterinarians. She is also a steady force within the practice, making sure that everyone is familiar with their pet’s home care programs. She is also a keen listener of both animals and their humans: How is a pet parent feeling about their dog’s progress today, and what level of home exercises can be balanced within any family’s busy schedule?

Karen has worked in animal care environments for more than 20 years, embracing a wide range of functions from business management to hands-on rehabilitation therapy. She first saw the power of rehabilitation care while working at a Colorado-based manufacturer of customized veterinary orthotic braces and prosthetic solutions. She learned quickly that the innovative devices used to improve pet’s mobility required physical therapy to maximize their benefits and decided to dedicate her energy to this segment of animal wellness.

Karen has participated in dog agility competitions for decades which has given her a front row seat to the critical importance of maintaining and increasing mobility for dogs of any age or physical condition.

Sheri Mounteer, MPT, CCRT

Physical Therapist

Sheri transformed a 20-plus year career in physical therapy on humans into rehabilitation therapy for dog and cats. Her physical therapy skills, love of animals, and the additional training in small animal rehabilitation have allowed her to successfully make this shift.

Sheri appreciates working with animals because they don’t have the same limitations that people do. Without expectations, animals don’t let their ego and psyche get in the way of their recovery. Sheri sees animals respond to therapy and experience amazing recoveries.

Sheri works with referring vets to develop the best treatment plans. She also works closely with pet parents to make sure they understand their pets disease/injury, what to expect and how to incorporate home exercise plans to help their pet.
Sheri is a passionate outdoorswoman who enjoys mountain biking, trail running, skiing and camping alongside her dog, Hannah. She is also an active volunteer with the Humane Society of the South Platte.
