Dr. Lindsay Mamula-Crippen - Veterinary Center of ParkerDr. Lindsay Mamula-Crippen, DVM, MBA, CVPM

Hello all! If you are reading this then you are interested in VCPI becoming your new home for veterinary care. Here’s a little information about me.

I am a native of Colorado. In high school I was an avid athlete playing volleyball, basketball, and soccer. I, also, loved the piano and started playing at the age of five. For as long as I can remember I have aspired to be a veterinarian. My animal care career started in high school. I worked as a kennel “kid” at our family veterinarian. Even though my role was small, I learned firsthand the importance the client places on feeling confident and comfortable with their pet care provider.

I attended Colorado State University (CSU) in Fort Collins studying Biology and Zoology. During college I worked at Lambspun of Colorado, a fiber arts gallery. While working there it was a necessity to acquire the skills of knitting, spinning, weaving and crocheting, but I, also, learned and saw first hand how important it is to manage a business. Those three years provided me the confidence and determination to become a veterinarian and a business owner. Upon graduation from CSU, I applied and was accepted at the University of Illinois College of Veterinary Medicine. I graduated in May 2003 with a Doctorate of Veterinary Medicine (DVM) and returned to Colorado. To enhance my entrepreneurial knowledge, I decided to continue school and graduated with a Master of Business Administration degree (MBA) from the University of Colorado at Denver.

My doctor career started soon after my return to Colorado as an emergency and critical care veterinarian on the overnight shifts for a large Castle Rock practice. Since I was the only veterinarian present at night I learned a lot of practical experience quickly. I worked my way onto the day shift as a general practitioner. After five years of practicing medicine there, I advanced in my career by becoming part owner of a practice in Castle Pines. I was a general practitioner as well as the primary manager of the multi-doctor practice for the next six years.

I moved to Parker in August 2014 and love it. I am calling my new home Veterinary Center of Parker, Inc. aka VCPI.

The final tidbit about me is my family. I married my wonderful husband in 2007. We have a charming and beautiful 6-year-old daughter and, of course, the furry family members are Black Diamond, Jack, Chloe, and Everett (all cats), Bucky (dog), Elsa (hamster) and Zoey (fish). I have a passion for photography, crafts, nutrition and CrossFit.

I look forward to meeting you and am excited to be a part of a dynamic team that offers compassionate care for your beloved furry or scaled family members!

P.S. We work as a team; you rely on my staff and me, the doctor, to prevent and heal, and I rely on you to tell me their story. We hope to gain your trust and confidence as your veterinary care provider to love and protect your pet.


Dr. Lindsay Mamula-Crippen - Veterinary Center of ParkerDr. Tiffany Colglazier, DVM, cVMA

I am a 4th generation Colorado native. I am new to the VCPI family but not new to the Parker area. I grew up in Parker and spent the majority of my childhood on the back of a horse or hanging out at the barn as a true “barn rat.” This experience fueled my love for animals both large and small as well as taught me hard work and dedication.

I received both my Doctor of Veterinary Medicine degree and B.S. in Environmental Health from Colorado State University. Although my initial interest after graduation was in equine medicine, I have since found a love for small animal medicine with a particular interest in improving the quality of life of our aging four-legged friends. In an effort to better manage pain I pursued acupuncture training through the Medical Acupuncture for Veterinarians course and am now certified in veterinary medical acupuncture (cVMA). By combining acupuncture and laser therapy with conventional western medicine we can keep our furry friends going strong into their senior years.

In my free time I enjoy spending time with my family and pets, hiking, gardening, skiing, and riding my horse. I am married to the most wonderful man and we have a daughter and of course the furry family… a cat, dog, and horse.

I look forward to meeting you and providing the compassionate care that your pet deserves.


Amy Rathbun - Certified Veterinary Technician - Veterinary Center of ParkerAmy Rathbun – Certified Veterinary Technician

Hi my name is Amy Rathbun. I was born outside of Chicago and moved here to Colorado when I was still very young and have loved it ever since! I have always had a love for animals and knew from a very young age that working with them was the right career for me. I attended the Bel-Rea Institute where I completed my schooling in March 2007 with an Associates of Applied Science in Animal Technology and from there went on to get my state Certification in June of 2007. I have had the pleasure of working in small and large animal clinics, a specialty clinic specializing in neurology and even enjoyed a brief stint in the pet insurance industry. I am happy to now call Veterinary Center of Parker, Inc. my home!

I have my own pets, which include a Bichon Friese named Ava (also known as “The Diva”) and a Quarter Horse named Shanti. In my free time you will likely find me outdoors hiking, horseback riding, camping; enjoying all Colorado has to offer, and of course spending time with my “fur babies”.

My true passion is working with animals and their families and I look forward to meeting you and your pets!


Katie Dandurand – Certified Veterinary Technician

I grew up in the sunny state of California as an outdoors girl, spending many days in mud puddles and climbing trees. I have my parents to thank for fostering my love of animals, teaching me that there is no greater gift to receive than the love of a pet – and we had many! Dogs, birds, and too many pocket pets to count, our family zoo was founded on love, and fostered with compassion. 

After receiving my bachelor’s degree from the University of Pennsylvania in 1999, I spent many years working in the human resources field but ultimately my love of animals called me to pursue a second career in veterinary medicine. I graduated from Bel-Rea in 2009 with top honors, and am very proud to be a CVT! I have a passion for surgery, dentistry, and anesthesia, and love caring for your pets as if they were my own. 

I currently live in Parker with my husband Dale and our four legged children including our Samoyed Misha, an Australian Shepherd named Choss, and our two cats, Hufflepuff and Luna Lovegood. During my time off I enjoy the outdoors of Colorado snow skiing, being a gym rat, and running endurance and obstacle course races. 


Alice Parker, Certified Veterinary Technician

Hi! My name is Alice Parker, I am from Charleston, South Carolina and moved to Colorado in 2015. After graduating from the Bel-Rea Institute as a certified veterinary technician, I joined the amazing team at Veterinary Center of Parker. I live in east Denver with my roommate, my French Bulldog Beans and our cats Butters, Phoebe, and Phineas. In my free moments, I enjoy going to concerts, exploring the mountains, and spending time with friends. I am so happy to be a part of the VCPI team and look forward to meeting you and your pets!


Lacey Vine, Certified Veterinary Technician (pending)

Hi, my name is Lacey Vine. I was born in Colorado and have lived here all my life. I’ve always had a huge passion for animals and half way through nursing school I realized I truly belong in a career where I can help animals and be happy every day I come into work. That is when I left nursing school and decided to pursue my education in veterinary medicine. In 2016, I attended Pima Medical Institute where I obtained my Veterinary Assistant certification. I then went to work as a vet assistant for about a year and then made the choice to further my education and go back to school to become a CVT. I just recently completed school and started my job at Veterinary Center of Parker. I absolutely love learning new things every day and getting to know the wonderful clients. I have an adorable pug named Sydney and two little squeaky guinea pigs named Bo and Benny. I look forward to being part of the VCPI family for a long time.


Lesley Perry - Veterinary Center of ParkerLesley Perry – Veterinary Assistant

Aloha! My name is Lesley Perry. I am a Native Hawaiian, born and raised on the island of Oahu. Though I miss the beautiful sandy beaches and lush green mountains of Hawaii, I have happily called Colorado my home since 2007. I am a graduate of the University of Hawaii at Manoa with a BA degree in Zoology. I have worked in the veterinary field as a Veterinary Technician/Assistant since 2005. My experience in the veterinary field has been with both general practice clinics as well as emergency hospitals. The hours that I have spent communicating with clients and helping to treat their pets, have taught me the importance of compassion, empathy, strength, knowledge and trust. All of which I strive to bring to each individual case.

When I’m not working, I enjoy simple pleasures such as taking my dogs on long walks/hikes, going on bike rides and relaxing in front of a movie. I share my life with my loving husband Chad, crazy anxious American Cocker Spaniel named Bosco, handsome German Shepherd named Max and sneaky Maine Coon/Tabby mix named Atticus.


JC Kaufman – Veterinary Assistant

My name is JC Kaufman and I was born and raised in Colorado. I grew up in Denver, then moved to Castle Rock in 4th grade. I grew up playing baseball, basketball, and soccer, but decided to pursue club soccer competitively with the Men’s 1986 Olympic developmental program. I graduated from Highlands Ranch high school in 2004 then went on to play 2.5 years of collegiate Div. II soccer for Cal State Chico in northern California. I earned my bachelors degree with a double major in Psychology/Sociology from the University of Colorado at Denver in 2011. After graduation I began volunteering/working at a local vet clinic where I found my love and passion for animals. I have three dogs: Sydney (9.5yr old cairn terrier), Koda (6yr old shepherd/husky mix), Haley (9yr old shepherd/Labrador mix); as well as two cats at home of which I love spending my free time with taking them for hikes, walks, camping, etc. I also enjoy traveling, going to the gym, hanging out with friends/family, and anything outdoors. I also still continue to play competitive soccer for the Denver Kickers and a few other leagues during the week to stay active and busy. I look forward to meeting you and your furry family here at Veterinary Center of Parker!


Karen Mullins - Client Care Representative - Veterinary Center of ParkerKaren Mullins – Client Care Representative

Ever since my first kitten at the age of 6, I have had a love and a need for animals in my life, and could not imagine a home without one (or 4!).

I grew up in southern Florida and moved to attend college in Charlotte, North Carolina, where I received a BA in Psychology. It was there I met my husband and best friend, and over the years we grew our family to include 2 daughters, 3 cats and a lovable, Lab mix, grand-dog named Bailey.

Our life path brought us to Colorado in 2000, and I soon found my niche in Client Care in the Veterinary field.

I am very excited to be a part of the front office team of the Veterinary Center of Parker, and couldn’t ask for a more compassionate group of highly skilled people to be working with. I look forward to getting to know you and all the members of your pet family!


Barb O’Connor – Client Care Representative

I’m fairly new to the Veterinary Center Family, but feel I have found a new home. I had worked for 12 years previously at a clinic in Centennial, and before that worked with a mobile veterinarian in Franktown. I grew up in northeastern Ohio, moved to Washington DC with United Airlines and met my husband there. He was originally from Montana and wanted to move west, so we settled on Denver. We have lived in Douglas County since 1978. Living on a bit of acreage, we’ve had horses, dogs, cats, birds, bunnies, rats and reptiles. Thanks to one of my now grown daughters, we got involved with raising Guide Dog pups through 4H with Guide Dogs for the Blind in 1990 and I’ve been doing it ever since. Once our children left home, I was still hooked on the process and am now on puppy number 28 but have switched organizations to Guiding Eyes for the Blind in New York. We get the pups at about 8-10 weeks old and keep them until they are 16-18 months old. It’s my job to teach them basic obedience skills, good house manners, and socialize them to just about anything they might encounter in the world with a blind partner. It’s always rewarding to see the light bulb come on as they mature and every dog teaches me something new.

When I’m not training a pup or working, I enjoy my 4 grandchildren when they visit, reading when I can, and spoiling my two forever dogs, Zorba and Mufasa (I didn’t name them) who were released from the guide dog program for health issues. Living on 5 acres requires a lot of outside maintenance time, which I love also.

I am looking forward to meeting the pets and people who come to The Veterinary Center of Parker for the loving, supportive and expert care we are able to provide. I feel the team I have joined is dedicated to giving each pet and owner the benefit of experience and compassion and I am eager to participate in the process.


Ayshei Castillo – Client Care Representative

My name is Ayshei Castillo and I was born and raised in Southern California.  I moved to Colorado in late September of 2016 and I am in love with my new home. I live with my boyfriend Scott and we have a fur baby named Murphy that we adopted from the Humane Society of South Platte River.  When I am not working I can be found going to the gym, hiking, or eating hot Cheetos while watching a movie on Netflix. I am currently attending CCD and in the process of completing my prerequisites to apply to the Vet Tech program at CCD. I am new to the Veterinary Center of Parker family and am looking forward to growing with this wonderful company!


Rachael Lesperance, Client Care Representative

I was born in Tucson, AZ and moved around quite a lot as a child because my father was in the Air Force. I have lived in 7 states and 2 countries. I moved to Colorado during the summer of 2017 and couldn’t be happier here!

I have a lifelong passion for animals passed on from my grandmother and mother, both of whom have been involved with several pet charities and rescues (not to mention all the family pets we had growing up!). I started working in the veterinary field 15 years ago. I spent some time working as an animal behaviorist and have even had some luck teaching my 9-year-old cat some tricks (he can shake, high-five, and beg, among other things). I find working with animals and the people that love them to be a truly rewarding experience and I look forward to it every day!

I live here in Parker with my husband, our dog Mac, and our cat Mister D. Outside of my work I enjoy hiking in the mountains, road trips to visit our Arizona family, and just relaxing with the critters while watching movies or reading a good book. I look forward to meeting you and your pets here at VCPI!
