I take great care in treating my patients with a gentle manner and enjoy teaching them about their oral health, so that they can be active participants in their care.” Dr. Mulligan and her family previously lived in Seattle, WA where she was actively involved with organized dentistry. She served on Executive Council, Membership Committee, and New Dentist Committee for the Seattle King County Dental Society.

Dr. Madeline Stead, DDS


Dr. Madeline Stead joined Grand Avenue Dental in May 2023. She completed her undergraduate studies and earned her Doctor of Dental Surgery degree from the University of Iowa in 2019. She then went on to work at a community health center in Cedar Rapids, Iowa for three years. She is happy to be back in the Twin Cities living and working very close to where she grew up. Dr. Stead loves that dentistry blends her creative and artistic abilities with her interest in the sciences, health, and wellbeing. She strives to provide each of her patients with the best individualized care possible through compassion and open communication. Being a general dentist feeds Dr. Stead’s passion because she enjoys seeing patients of all ages and loves the daily variety of patients and dental health opportunities. “Taking the time to build relationships with my patients is very important to me because I want them to feel comfortable in my care.” In her free time, Dr. Stead enjoys traveling, trying new restaurants, staying active outdoors, and spending time with her family, friends, and big Bernedoodle (Bernese Mountain Dog / Poodle), Henry.

Dr. Paul Amble, DDS

Dentist - retired
In 1985 I opened my dental practice in St. Paul’s Lowertown. Four years later, we bought our building on Grand Avenue where the practice continues to this day. The practice grew and flourished. We added on to the building twice, and my hair, or what’s left of it, turned grey. In 2019 I asked Dr. Megan Mulligan to join me as an associate. She and I shared very similar practice philosophies, and I knew her to be a skilled clinician. The association was so successful, I began to lay plans to reduce my schedule until I would eventually retire. Two years later, Dr. Mulligan purchased the practice. We did this quietly to transition with as little disruption to patient care as possible. This was important to me as I had heard so often from new patients that they transferred to me because their old practice was abruptly sold, and they felt abandoned or handed off. Early in 2023 I had a fall on the ice and this sped up my retirement, if only by a handful of months. People often ask me, “Why dentistry?”, or “What do you like most about dentistry?”. The answer is that I have always derived great satisfaction from taking care of people, and my profession afforded me the opportunity to do just that. Some of you have, amazingly, been with me since those early days, and some of you I have seen only a few times. No matter how long you have been a patient at Grand Avenue Dental, you have all been part of a very meaningful professional life for me. I appreciate you, I am grateful for you, and I thank you.
