Meet the Sunrise of Walnut Creek Team

We are pleased to introduce you to some of the team members who make our community a wonderful place to call home.

Walnut Creek ED - Marvin JungMarvin Jung

Executive Director

“When I work with our residents, I feel like I’m making new friends. Seeing their smiles and hearing their laughter makes each day here special. I have a deep respect for seniors and their infinite wisdom and knowledge.

I began my fascinating, wonderful journey with seniors in 1997. Assisted living has been my passion for 18 years, and I have worked at every level to better understand the needs of our residents. I have been the Executive Director of Sunrise at Walnut Creek for nearly five years and have loved every minute of it. I feel fortunate to be part of such an amazing community, working with the best residents, family members and team members around!”


Sunrise of Walnut Creek Team Member KelleyKelley Donovan

Director of Sales

After caring for her own aging loved ones, Kelley was inspired to change careers and join the senior living industry. Having worked with families in the mortgage industry for 20 years, Kelley is a seasoned professional who takes pride in helping elders and their loved ones with the transitions that come with aging.

It is most rewarding to Kelley to be a member of an organization whose mission, values, and principles of service align so closely with her own. She is a compassionate elder advocate who enjoys baseball, sailing, the theatre, and cooking with family and friends in her spare time.


Walnut Creek HCM - Kimberly AshtonKimberly Ashton

Healthcare Manager

Kim came to work at Sunrise in 2014 after achieving her lifelong dream of becoming a nurse. She began as a medication care manager, was promoted to wellness nurse and then rose to her current position as healthcare manager.

“I love working at Sunrise because the organization is very family-oriented—residents’ families are always welcome to participate in activities such as the Sunrise Luau or holiday barbecues,” she said. “In addition, the Sunrise of Walnut Creek staff is its own family, and everyone extends a helping hand to one another.”

Kim is compassionate about her residents and staff, and always puts their needs before her own. She loves working with the residents and their families because she believes in advocating for their rights, especially when they are not able to communicate.


Walnut Creek ALC - Sonya ValesSonya Vales

Assisted Living Coordinator

“When I was younger my mother was a caregiver, and I used to visit her and watch how much she enjoyed taking care of people. With her as an example, I began my own senior caregiving career when I was 15 and it has continued for the past 27 years.

Sunrise is an extended family, from the residents to the team members. During my time working with Sunrise, I have been able to successfully raise seven children and be the proud grandmother to Niko, my only grandchild. I enjoy shopping and spending time with family in my free time.”


Walnut Creek MC - Ron Havens

Ron Havens

Maintenance Coordinator

"During my 30 years of working for seniors, what I find the most rewarding is the twinkle in our residents’ eyes and the smiles that light up their faces when you have done something so simple for them. I love knowing that we give them a safe, clean and comfortable place to live.

At Sunrise, our residents are our highest priority. This is their home and we are family. Every person on our staff truly cares and it shows in all they do."


Walnut Creek RC - Rona Cristobal-Valdez

Rona Cristobal-Valdez

Reminiscence Coordinator

"My educational background includes a double major in sociology and gerontology with a minor in medical sociology and an associate degree in vocational nursing.

I was born and raised in Hawaii, and grew up with the Aloha spirit instilled in me. For me, taking care of seniors is a way of giving back and making each day a pleasant day. My residents have a wealth of knowledge, and I love to learn more about each person, their families, and their experiences each day.

In 2014, I started out as a Medication Care Manager at Sunrise, but I transitioned to become full-time Wellness Nurse. Most recently, I have received the opportunity to serve as the Reminiscence Coordinator here.

Through the years, I’ve built relationships with our residents and their families. I am especially passionate about my Reminiscence residents and caring for them in my new role. There is no feeling that compares to what I feel deep inside when providing gentle care. Sharing one on one time with the residents is what I look forward to each day.

I love working at Sunrise because I am honored to work with a fabulous, top-notch team to assist with caring for these unique people with whom I’m able to share my Aloha.”


Walnut Creek BOC - Iryn Macamay

Iryn Macamay

Business Office Coordinator

"Since 2004, I have been participating in volunteer work with seniors. It has not ever crossed my mind until now that my current career path with seniors gives me the most sense of fulfillment and purpose.

I am so privileged to be part of a team that values camaraderie and works towards a common goal of ‘championing quality of life for all seniors.'

My favorite part of what I do is being able to render my time and service—may it be a resident, family member, or a fellow team member. If I am able to extend help in any way and make it a little easier for someone, I feel like I have accomplished something.

In my spare time, I enjoy going out for hikes, and I love to cook, eat out, and try something new every time."


Walnut Creek AVC - Lucinda Smith

Lucinda Smith-Cruciani

Activity & Volunteer Coordinator

"I have had the pleasure of engaging residents in all aspects of senior care. I learned this was my passion well before I went to Chabot College to obtain my certification in Activities and Social Services Design. In order to fulfill this passion of mine, I completed the Emergency Medical technician program, but I actually found my calling within the geriatric field after an experience during clinical training. I felt I was able to help patients who needed a little something more.

Through the years, I have gained experience from caring for my family, singing to seniors as an entertainer at several communities all over the Bay area, and working as an Activity Director in skilled nursing, assisted living, and memory care communities since 2002. 

My favorite Principle of Service is ‘Celebrating Individuality.’ While getting to know our residents, we learn their life experiences and how to meet their needs. It feels great to connect and build bonds.”


Walnut Creek DSC - Louise Miloseski

Louise Miloseski

Dining Services Coordinator

“I'm Louise Miloseski, and I was born in Prilep, Macedonia. I received my business degree and came to the US in 1973, settling in the Detroit, Michigan area.

After relocating to the US, I obtained my food operator license to run my own restaurant which served a diverse international menu for many years. Eventually, I transitioned my career into dietary services by working as the Head Patient Cook at St. Mary Mercy Hospital in Livonia, Michigan. There, I was responsible for patient dietary services. I planned and initiated hospital food preparation to meet specialized meal schedules and ran a kitchen that supported over 250 patients.

I recently moved to Northern California to be near my son, daughter, and wonderful grandchildren. I started working at Sunrise of Walnut Creek to utilize my decades of dietary cooking experience and to help residents in need.

My favorite part of working at Sunrise is building relationships with many of our residents, preparing food that will make them happy and healthy, and creating a food service culture which raises our kitchen service standards to best in class."
